 Chao Hick Tin JA (delivering the judgment of the court):
Introduction
1       In our recent decision in The
 Royal Bank of Scotland NV (formerly known as ABN Amro Bank NV) and 
others v TT International Ltd (nTan Corporate Advisory Pte Ltd and 
others, other parties) and another appeal [2015] 5 SLR 1104 ("TT International”)
 at [185] and [215], we explained that the principle of finality is an 
integral part of justice. Judicial decisions, if they are to mean 
anything at all, must confer certainty and stability. People must be 
able to order their affairs according to the settled conviction that the
 last word of the court is the last word, and that the last 
full stop in a written judgment is not liable to be turned into an 
open-ended and uncertain ellipsis. As Harlan J said in Mackey v United States 401 US 667 (1971) at 690–691:
…
 It is, I believe, a matter of fundamental import that there be a 
visible end to the litigable aspect of the criminal process. Finality in
 the criminal law is an end which must always be kept in plain view. … 
If law, criminal or otherwise, is worth having and enforcing, it must at
 some time provide a definitive answer to the questions litigants 
present or else it never provides an answer at all. Surely it is an 
unpleasant task to strip a man of his freedom and subject him to 
institutional restraints. But this does not mean that in so doing, we 
should always be halting or tentative. No one, not criminal defendants, 
not the judicial system, not society as a whole is benefited by a 
judgment providing [that] a man shall tentatively go to jail today, but 
tomorrow and every day thereafter his continued incarceration shall be 
subject to fresh litigation on issues already resolved.
2       However,
 the cost of error in the criminal process is measured not in monetary 
terms, but in terms of the liberty and, sometimes, even the life of an 
individual. For this reason, where criminal cases are concerned, the 
principle of finality cannot be applied in as unyielding a manner as in 
the civil context, and it seems that the court should, in exceptional cases, be able to review its previous decisions where it is necessary
 to correct a miscarriage of injustice. The question would then be this:
 when do these conditions obtain? In the present criminal motion ("the 
Present Application”), we confront this very issue.
The facts
3       In
 2010, the applicant in the Present Application, Jabing Kho ("the 
Applicant”), was tried and convicted of the offence of murder, and was 
sentenced to suffer the then mandatory punishment of death: see Public Prosecutor v Galing Anak Kujat and another [2010] SGHC 212 ("HC (Conviction)”)
 (the said Galing Anak Kujat in this case report was the Applicant’s 
co-accused at the trial). The Applicant’s appeal against his conviction 
was dismissed in 2011 (see Kho Jabing and another v Public Prosecutor [2011] 3 SLR 634 ("CA (Conviction)”)).
 Following the enactment of the Penal Code (Amendment) Act 2012 (Act 32 
of 2012) ("the 2012 Amendment Act”), all persons who commit the offence 
of murder, save for those who commit murder within the meaning of s 300(a)
 of the Penal Code (Cap 224, 2008 Rev Ed) ("the PC”), may be sentenced 
to a term of life imprisonment and caning instead of being sentenced to 
death. Crucially, the 2012 Amendment Act also provided that all persons 
who were convicted of murder before the entry into force of the Act 
could apply to be re-sentenced under the new sentencing framework.
4       The
 Applicant duly applied to be re-sentenced. On 30 April 2013, the Court 
of Appeal clarified that he was guilty of murder within the meaning of 
s 300(c) of the PC and remitted the matter to the High Court 
for a fresh sentence to be passed. On 14 August 2013, a High Court judge
 ("the Re-sentencing Judge”) re-sentenced the Applicant to a term of 
life imprisonment and 24 strokes of the cane (see Public Prosecutor v Kho Jabing [2014] 1 SLR 973 ("HC (Re-sentencing)”)).
 The Prosecution appealed and the matter came before us. On 14 January 
2015, we allowed the Prosecution’s appeal by a majority of 3:2, and 
substituted the sentence of life imprisonment and caning with a sentence
 of death (see Public Prosecutor v Kho Jabing [2015] 2 SLR 112) ("CA (Re-sentencing)”)).
 The Applicant then petitioned the President of the Republic of 
Singapore for clemency, but his application was rejected, and on 
19 October 2015, the President ordered that the sentence of death be 
carried into effect on 6 November 2015.[note: 1]
5       On
 3 November 2015, Mr Ravi s/o Madasamy filed Criminal Motion No 23 of 
2015 ("CM 23/2015”) seeking to have the Applicant’s conviction set aside
 on the ground that it was unconstitutional. On 4 November 2015, the 
Applicant applied by way of the Present Application to set aside the sentence of death
 imposed on him. The Attorney-General was named as the respondent in 
CM 23/2015, while the Public Prosecutor was named as the respondent in 
the Present Application. Both applications were scheduled for hearing 
before us on an urgent basis, and we heard them on the morning of 
5 November 2015. At the start of the hearing, counsel for the Applicant,
 Mr Chandra Mohan K Nair, informed us that he had only been instructed 
the day before and therefore had not had sufficient time to prepare his 
client’s case. In the circumstances, we thought it fair and prudent to 
adjourn both applications, and ordered that the sentence of death 
imposed on the Applicant be stayed pending their determination.
6       At
 the resumed hearing of the applications on 23 November 2015, Mr Ravi 
applied to withdraw CM 23/2015. We granted that request, but clarified 
that as a result of the withdrawal, the issue of whether Mr Ravi had the
 locus standi to bring the application (the Public Prosecutor 
contended that he did not) did not arise for decision, and further, that
 we expressed no views on that issue. We then heard Mr Mohan on the 
merits of the Present Application and reserved judgment.
The issues
7       In
 broad terms, the Present Application raises two issues. The first is 
whether, and in what circumstances, the Court of Appeal may reopen its 
previous decision in a concluded criminal appeal, which was to have been
 final. The second is whether it should do so in the present case. We 
will discuss each issue in turn.
When should the Court of Appeal reopen its decision in a concluded criminal appeal?
8       Applications
 to reopen concluded criminal appeals have burgeoned. In 2015, 11 
criminal motions of this nature were filed by accused persons in the 
Court of Appeal alone: six seeking leave to appeal against the outcome 
of Magistrate’s Appeals[note: 2]
 and five seeking to move this court to re-examine its own decisions in 
concluded criminal appeals arising from decisions made by the High Court
 at first instance.[note: 3]
 Of these 11 criminal motions, eight were dismissed summarily for being 
wholly without merit (oftentimes without the respondent in the 
application concerned being called on to respond);[note: 4] one was withdrawn;[note: 5] one has yet to be heard;[note: 6]
 while the last (the Present Application, which was also the last 
criminal motion of this nature filed in this court in 2015), we reserved
 to consider more carefully. This figure does not include the 
innumerable criminal motions filed in the High Court, some of which, we 
have no doubt, also sought to have the High Court reopen its previous 
decisions in concluded Magistrate’s Appeals, there being no avenue for a
 further appeal against a decision made by the High Court in the 
exercise of its appellate criminal jurisdiction.
9       We do not think the present state of affairs conduces to justice. As Jackson J candidly remarked in Brown v Allen
 344 US 443 (1953) at 537, "[i]t must prejudice the occasional 
meritorious application to be buried in a flood of worthless ones”. We 
are still paradigmatically a one-appeal jurisdiction. The filing of 
unmeritorious applications to reopen concluded criminal appeals takes up
 valuable resources which can and should go towards the 
disposal of cases which are coming up on appeal for the first time. For 
this reason, we propose to lay down some guidelines to explain when, and
 in what circumstances, this court should reopen a concluded criminal 
appeal. First, we will examine the way in which this issue has developed
 in our jurisprudence. Second, we will consider the position in other 
jurisdictions in search of guiding principles which may be used to 
develop a coherent system in Singapore. Finally, we will gather up the 
threads of our analysis and distil certain guidelines for application in
 future cases.
The development of the Court of Appeal’s power of review
10     Prior
 to 2010, this court held, in a quartet of decisions, that once it had 
delivered its judgment in a criminal appeal, it was functus officio and had no jurisdiction to reopen the matter and reconsider its substantive merits: see Abdullah bin A Rahman v Public Prosecutor [1994] 2 SLR(R) 1017 ("Abdullah”), Lim Choon Chye v Public Prosecutor [1994] 2 SLR(R) 1024, Jabar bin Kadermastan v Public Prosecutor [1995] 1 SLR(R) 326 and Vignes s/o Mourthi v Public Prosecutor [2003] 4 SLR(R) 518 ("Vignes”). These cases will be collectively referred to hereafter as "the Vignes
 line of decisions”. The reason given was that once this court had heard
 and disposed of an appeal, its statutorily-conferred appellate 
jurisdiction ceased; and as a creature of statute, it did not, in the 
absence of specific statutory authorisation, have any jurisdiction to reopen the case to entertain further arguments on the merits of the matter (see Vignes at [4]). We will refer to this line of argument as "the functus officio argument”.
The exception laid down in Koh Tony
11     In Koh Zhan Quan Tony v Public Prosecutor and another motion [2006] 2 SLR(R) 830 ("Koh Tony”), an important gloss was added to the above position. The applicants in Koh Tony
 were charged with murder, but were convicted by the High Court of the 
lesser offence of robbery with hurt. Upon appeal by the Prosecution in 
Criminal Appeal No 2 of 2005 ("CCA 2/2005”), the Court of Appeal 
reversed the High Court’s decision, substituting the convictions for 
robbery with hurt with convictions for murder. The applicants then filed
 criminal motions arguing that the Court of Appeal did not have the 
jurisdiction to hear CCA 2/2005 because the Supreme Court of Judicature 
Act (Cap 322, 1999 Rev Ed) (we will hereafter refer to this Act and its 
legislative successors generically as "the SCJA”) only permitted the 
Prosecution to appeal against the acquittal of an accused, which, the applicants argued, was not the position in their case because they had in fact been convicted, albeit of a lesser offence. The Prosecution argued that the criminal motions should be dismissed in limine on the basis that the Court of Appeal, having already disposed of the substantive merits of CCA 2/2005, was functus officio and therefore had no jurisdiction to consider the motions.
12     The Court of Appeal took the objection in two parts. First, it considered whether it had the jurisdiction – in the sense of "authority … to hear and determine a dispute that is brought before it” (see Muhd Munir v Noor Hidah and other applications [1990] 2 SLR(R) 348 ("Muhd Munir”)
 at [19]) – to hear the criminal motions. The court held that it did. 
The gist of the criminal motions was whether the court had the 
jurisdiction to hear CCA 2/2005 in the first place. The court held that 
this was a matter which ought to have formed part of CCA 2/2005, and 
thus, "[the] court remains properly seised of the present case in so far
 as the question of jurisdiction is concerned” [emphasis in original] (see Koh Tony at [23]). Second, the court considered whether it had the power
 – in the sense of the "capacity to give effect to its determination by 
making or granting the orders or reliefs sought by the successful party”
 (see Muhd Munir at [19]) – to determine the issue raised in 
the criminal motions. The court likewise held that it did because 
s 29A(4) of the SCJA gave it "full power to determine any question 
necessary to be determined for the purpose of doing justice in any case 
before the Court”, and there was no doubt that the question of whether 
the court even had the jurisdiction to hear CCA 2/2005 to begin with 
satisfied this criterion.
13     Having
 concluded that it had both the jurisdiction and the power to hear the 
criminal motions, the court then went on to say that even though the 
matters presented in the criminal motions "ought, ideally, to have been 
raised and considered during the hearing of [CCA 2/2005]” [emphasis in 
original omitted] (see Koh Tony at [19]), two factors weighed 
in favour of hearing the criminal motions. The first was the importance 
of the legal issue raised, which, the court observed, was one that "would have a potentially significant impact on future cases” [emphasis in original] (see likewise Koh Tony at [19]); the second was the gravity of the matter, viz, "[it was] a criminal
 appeal involving a final appellate court where life and liberty are at 
stake” [emphasis in original] (at [24]). However, the court clarified 
that its decision was "confined to the precise question of whether the court has the jurisdiction and power to consider if the earlier court had the jurisdiction to entertain [CCA 2/2005]” [emphasis in original] (at [29]). The court also clarified that it remained functus officio
 as far as the substantive merits of CCA 2/2005 were concerned as it had
 "already heard and ruled on the issues associated therewith” (at [22]).
14     Even though the Court of Appeal in Koh Tony took pains to maintain fidelity with the Vignes line of decisions, it also ameliorated the strictness of that line of authorities. The position after Koh Tony
 was that if an application to reopen a concluded criminal appeal was 
premised on a challenge to the Court of Appeal’s jurisdiction to hear 
the appeal in the first place, the court would still be seised 
of jurisdiction to hear the matter even though it had already ruled on 
the merits of the appeal. Although the position taken by this court in Koh Tony was framed as a narrow exception to the Vignes line of decisions, it was in effect a significant departure. Prior to Koh Tony, the position had been that the Court of Appeal’s jurisdiction was completely exhausted by the disposal of the criminal appeal before it, and thus, the court did not have any residual jurisdiction to entertain any
 further applications in relation to the matter, be it a further appeal,
 an application to adduce further evidence, an application for a review 
or otherwise. That was no longer the case after Koh Tony.
The decision in Yong Vui Kong (Jurisdiction) 
15     It did not take long for the inroads made by Koh Tony to flower. In Yong Vui Kong v Public Prosecutor [2010] 2 SLR 192 ("Yong Vui Kong (Jurisdiction)”),
 the applicant had earlier been convicted of trafficking in a quantity 
of drugs that attracted the death penalty. He had filed a notice of 
appeal, but had subsequently elected to withdraw his appeal. Sometime 
later, he filed a criminal motion petitioning the Court of Appeal to 
treat his previous withdrawal of his appeal as a nullity and to restore 
his appeal for hearing. The Prosecution argued that the Court of Appeal 
had no jurisdiction to hear the criminal motion because the applicant’s 
appeal, once withdrawn, was deemed to have been dismissed on its merits,
 and thus, the court was functus officio and could not hear any further appeal against the applicant’s conviction.
16     On
 the facts, the Court of Appeal held that the applicant had been 
labouring under a fundamental mistake when he withdrew his appeal. He 
had been under the impression then that he would have to lie to the 
court in order to pursue his appeal (which would have run counter to his
 settled religious convictions), but this was incorrect because it was 
open to him to challenge his conviction and sentence solely on legal 
grounds. Thus, the court held that the applicant’s withdrawal of his 
appeal was a nullity and allowed him to proceed with his appeal (at 
[28]). For present purposes, what is more important is that the court 
went on, in a lengthy obiter dictum, to express its view that even if
 the substantive merits of the appeal had already been heard and 
decided, it might still have the jurisdiction to hear further arguments 
on those substantive merits. At [16], Chan Sek Keong CJ, who delivered 
the grounds of decision of the court, said:
Another
 argument which this court should take into account (but which has never
 been addressed to the court), is that Art 93 of the Constitution [of 
the Republic of Singapore (1985 Rev Ed, 1999 Reprint)] vests the 
judicial power of Singapore in the Supreme Court. The judicial power
 is exercisable only where the court has jurisdiction, but where the 
SCJA does not expressly state when its jurisdiction in a criminal appeal
 ends, there is no reason for this court to circumscribe its own 
jurisdiction to render itself incapable of correcting a miscarriage of 
justice at any time. … [emphasis added]
17     The passage just quoted represented the quietus of the functus officio argument. There is no question that jurisdiction (in the sense of authority) can only be conferred by statute (see Re Nalpon Zero Geraldo Mario [2013] 3 SLR 258
 at [14]–[20]). However, whenever a matter before the Court of Appeal 
concerns an appeal against a decision made by the High Court in the 
exercise of its original criminal jurisdiction, this court is already 
properly seised of jurisdiction pursuant to s 29A(2) of the SCJA. The 
only issue is whether this statutorily-conferred jurisdiction comes to 
an end once a decision is made on the substantive merits of the appeal. 
On this, the SCJA is silent. However, if one accepts the central premise
 in Koh Tony – viz, that the Court of Appeal’s jurisdiction in respect of a criminal appeal is not exhausted by the rendering of a decision on the substantive merits (which is the antithesis of the functus officio argument) – then the demise of the functus officio argument is inevitable.
18     Even though it did not say so explicitly, the Court of Appeal in Yong Vui Kong (Jurisdiction) appeared to accept the premise of Koh Tony. It was on this basis that the court held that the operative question was not whether it could reconsider its previous decision in a concluded criminal appeal (in the sense of whether it had the jurisdiction to do so), but whether it should (in the sense of whether it should exercise its power to do so). At [14]–[15] of Yong Vui Kong (Jurisdiction), the court said:
14    It is not uncommon in other jurisdictions, such as the United States, for new exculpatory evidence to be discovered, eg,
 DNA evidence which can show almost conclusively that the blood found at
 the scene of the crime or on the body of the deceased (in murder cases)
 was not that of the accused. There may be other types of evidence which
 could have the same effect, eg, new documentary evidence which was not discovered during the trial or the appeal. In such cases, it would be in the interest of justice that the court should have the power to correct the mistake, rather than rely on the Executive to correct what is essentially an error in the judicial process. In our context, this
 court should consider or reconsider whether it has the power to review 
its own decisions which are demonstrably found to be wrong. …
15    …
 Suppose, in a case where the appellate court dismisses an appeal 
against conviction and the next day the appellant manages to discover 
some evidence or a line of authorities that show that he has been 
wrongly convicted, is the court to say that it is functus and, therefore, the appellant should look to the Executive for a pardon or a clemency? In circumstances where there is sufficient material on which the court can say that there has been a miscarriage of justice, this court should be able to correct such mistakes.
[emphasis added in italics and bold italics]
19     We
 thus see a gradual shift in the attitude of the Court of Appeal where 
reviews of its previous decisions in concluded criminal appeals are 
concerned. Whereas it once confined reviews to the specific question of 
whether it even had the requisite jurisdiction to hear the appeal to 
begin with, it now indicated (albeit obiter) that it was prepared to review the merits of its earlier decision if it would be in the interests of justice to do so. The principle stated by Chan CJ in Yong Vui Kong (Jurisdiction)
 was that the Court of Appeal should engage in a review of the merits 
"where there is sufficient material on which the court can say that 
there has been a miscarriage of justice” (at [15]).
Post-Yong Vui Kong (Jurisdiction) cases
20     After the decision in Yong Vui Kong (Jurisdiction), there were three instances where this court reconsidered the substantive merits of a concluded criminal appeal: Ramalingam Ravinthran v Attorney-General [2012] 2 SLR 49 ("Ramalingam”), Yong Vui Kong v Public Prosecutor [2012] 2 SLR 872 ("Yong Vui Kong (Prosecutorial Discretion)”) and Quek Hock Lye v Public Prosecutor [2015] 2 SLR 563 ("Quek Hock Lye”).
 These cases share three common features: (a) first, all these cases 
involved attempts by an accused person to reopen a criminal appeal which
 had been decided against him (see Ramalingam at [16], Yong Vui Kong (Prosecutorial Discretion) at [1(a)] and Quek Hock Lye
 at [22]); (b) second, all three cases involved constitutional issues 
which had not been considered at the hearing of the appeal and which, 
depending on how they were resolved, could have an impact on the outcome
 of the appeal; and (c) third, all of them involved the imposition of a 
capital sentence.
21     In Ramalingam,
 the applicant was convicted and sentenced in 2009 for trafficking in a 
quantity of drugs which attracted capital punishment, and his appeal was
 dismissed by the Court of Appeal in 2011. Thereafter, he filed a 
criminal motion in the Court of Appeal arguing that his right to equal 
treatment under Art 12(1) of the Constitution of the Republic of 
Singapore (1985 Rev Ed, 1999 Reprint) ("the Constitution”) had been 
violated by the Attorney-General’s decision to prosecute a co-offender 
involved in the same criminal enterprise on a non-capital charge. On 
that basis, the applicant sought to set aside the sentence of death 
imposed on him and have it replaced with a non-capital sentence. The 
Prosecution argued that the Court of Appeal, having already delivered 
its judgment on the applicant’s appeal, was functus officio and no longer had the jurisdiction to hear his criminal motion.
22     The
 court disagreed, and in the process, made a number of observations 
about the juridical basis of its authority and power to reopen concluded
 criminal appeals. The court began by distinguishing between two 
distinct but related concepts. The first was the principle of functus officio, which, it stated, applied to the court and related to the exhaustion of the court’s jurisdiction (at [10]); the second was the principle of finality, which was a broader concept that applied to prevent parties
 from re-litigating issues that had already been decided by the court 
(at [11]). The court went on to explain that in the criminal context, 
the line between the two was blurred. At [12]–[13], the court stated (per Chan CJ):
12    In Yong Vui Kong (Jurisdiction), this court recognised that the principle of functus officio, as laid down in the Vignes line of decisions, was based on the policy considerations underlying the principle of finality. In the criminal context, the functus officio principle is a self-limiting principle applied
 by this court so as not to open the floodgates to frivolous and 
unmeritorious applications for previous criminal judgments to be 
reviewed. However, the relevant statutory provisions governing 
criminal appeals (previously Pt V of the [SCJA] and now Div 1 of Pt XX 
of the Criminal Procedure Code 2010 (Act 15 of 2010)) do not expressly 
state when the court is functus officio.
13    In this light, it was observed in Yong Vui Kong (Jurisdiction) that where this court, being the final appellate court in this jurisdiction, had made a mistake of fact or law which had caused a person to be convicted and punished, it must have the power to correct its own mistake so as to avoid a miscarriage of justice. …
[emphasis added in italics, bold italics and underlining]
23     In
 the criminal context, the bar to reopening a concluded appeal is 
premised more on policy concerns over finality rather than on the ground
 of the Court of Appeal’s lack of jurisdiction. Thus, following Koh Tony and Yong Vui Kong (Jurisdiction), the question is one of whether the court’s power to review a concluded criminal appeal should be exercised. On the facts of Ramalingam, the court decided to hear the applicant’s criminal motion because the substantive issue in contention – viz,
 the relationship between the prosecutorial discretion conferred on the 
Attorney-General under Art 35(8) of the Constitution and the right to 
equality before the law under Art 12(1) of the same – was one which 
"need[ed] to be examined in greater detail and clarified in the public 
interest” (at [17]).
24     In 
summary, the approach taken in Singapore thus far has been one of 
incremental development. At present, the position seems to be that this 
court has the inherent power to reopen a concluded criminal appeal to 
correct mistakes "in circumstances where there is sufficient material on
 which the court can say that there has been a miscarriage of justice” 
(see Yong Vui Kong (Jurisdiction) at [15]). This power, which 
we will refer to as the power of "review” to distinguish it from both 
the usual appellate function of this court and the quite different 
revisionary jurisdiction which the High Court exercises over inferior 
tribunals, is one whose ambit has yet to be fully explored.
The position in other jurisdictions
25     We
 now turn to consider the position in some other jurisdictions. Before 
we proceed, we ought to point out that many jurisdictions have pursued a
 solution through legislation. For obvious reasons, some of the 
solutions which they have fashioned through legislative intervention are
 not available to this court. However, the principles which undergird 
their operation are. And it is to these principles that we turn in order
 to derive some guidance.
England and Wales
26     Until
 recently, the position in England and Wales was that no appeal could be
 reopened once it had been decided on the merits, save for a limited 
exception which applied only to decisions of the House of Lords (see 
K R Handley, Spencer Bower and Handley: Res Judicata (LexisNexis, 4th Ed, 2009) at para 5.06). This rule also applied to criminal appeals, even where there was fresh evidence (see Regina v Pinfold [1988] QB 462).
 In the criminal context, this absolute bar admitted of only two 
exceptions. The first was where the decision of the court was a nullity;
 the second was where there had been a defect in procedure which had 
occasioned injustice (see Regina v Daniel [1977] 2 WLR 394 ("R v Daniel”)).
27     The law in England and Wales underwent a sea change with the decision of the English Court of Appeal in Taylor and another v Lawrence and another [2002] 3 WLR 640 ("Taylor”). The issue in Taylor
 was whether an appeal should be reopened on the ground that there was 
new evidence which disclosed that the appellate court’s decision might 
have been tainted by apparent bias. Although the application to reopen 
the appeal in question was dismissed on its merits, the English Court of
 Appeal held, as a matter of law, that it had the power to reopen a 
concluded appeal "to avoid real injustice in exceptional circumstances” 
(at [54]). This power, the court explained, arose out of its character 
as a court of justice and was "necessary to achieve the dual objectives 
of an appellate court” (at [50]), which were, first, to ensure justice 
between the litigants and, second, to ensure public confidence in the 
administration of justice by remedying wrong decisions as well as by 
clarifying and developing the law and setting precedents (at [26]).
28     The ruling in Taylor
 was soon codified by the introduction of r 52.17 of the Civil Procedure
 Rules 1998 (SI 1998 No 3132) (UK) ("the English CPR”), which provided 
that the English Court of Appeal and the English High Court had the 
power to reopen a final determination of an appeal where the following 
three cumulative conditions were met (see r 52.17(1)):
(a)     it was necessary to do so in order to avoid real injustice;
(b)     the circumstances were exceptional and made it appropriate to reopen the appeal; and
(c)     there was no alternative effective remedy.
29     In the later case of In re Uddin (A Child) [2005] 1 WLR 2398 ("Uddin”),
 the central question related to the circumstances in which it could be 
said that the facts were so "exceptional” that recourse to r 52.17 of 
the English CPR was appropriate. In Uddin, the English High 
Court had earlier held that a mother had attempted to cause serious 
injury to her child. The mother applied to the English Court of Appeal 
for leave to appeal against the English High Court’s decision, but was 
unsuccessful. A few months later, the mother applied to the English 
Court of Appeal to reopen her application for leave to appeal on the 
ground that there was new evidence that cast doubt on the expert 
evidence upon which the English High Court’s decision had been based.
30     The
 English Court of Appeal dismissed the mother’s application to reopen 
her earlier leave application. Dame Elizabeth Butler-Sloss P, delivering
 the judgment of the court, started by considering the threshold that 
had to be met before a concluded "appeal” (which is defined in 
r 52.17(2) of the English CPR as including an application for leave to 
appeal) would be reopened – ie, "how exceptional is exceptional?” (see Uddin
 at [16]). In her view, the case had to be one "where it is demonstrated
 that the integrity of the earlier litigation process, whether at trial 
or at the first appeal, has been critically undermined” (at [18]). The 
reason for this, she explained, was that a court exercising its 
jurisdiction under r 52.17 was not "solely concerned with the case where
 the earlier process has or may have produced a wrong result [that being
 the domain of an appeal] … but rather, at least primarily, with special
 circumstances where the process itself has been corrupted” (at [18]). 
According to Dame Elizabeth, it was this "corruption of 
justice” [emphasis in original] (at [18]) that, as a matter of policy, 
was "most likely to validate an exceptional recourse; a recourse that 
relegates the high importance of finality in litigation to second place”
 and justified the reopening of a concluded appeal (at [18]).
31     It
 is important to note that Dame Elizabeth did not go so far as to say 
that the introduction of fresh evidence could in no circumstances 
justify the reopening of a concluded appeal in the absence of some other
 factor which had corrupted the litigation process. She held that while a
 case where the litigation process had been corrupted was "the paradigm 
case”, it was not necessarily the only case (at [20]). She 
explained that it might be possible for the discovery of fresh evidence 
to justify reopening a concluded appeal if "the injustice that would be perpetrated if the appeal is not reopened [is] … so grave as to overbear the pressing claims of finality in litigation”
 [emphasis added] (at [21]). In this regard, it was not sufficient to 
show a "real possibility” that the previous decision was wrong; instead,
 the party seeking to reopen the appeal had to go further to show that 
there was a "powerful probability” that an erroneous result had in fact been arrived at (at [22]). In closing, Dame Elizabeth succinctly summarised the position in the following manner (at [22]):
…
 That test [of whether the earlier litigation process has been 
critically undermined] will generally be met where the process has been 
corrupted. It may be met where it is shown that a wrong result was earlier arrived at. It will not be met where it is shown only that a wrong result may have been arrived at. [emphasis added in italics and bold italics]
32     In the recent case of Regina v Yasain [2015] 3 WLR 1571 ("Yasain”),
 the Criminal Division of the English Court of Appeal had occasion to 
consider whether it likewise had the power to reopen a concluded 
criminal appeal. We will return to the facts of the case at a later 
stage (see [72] below), but the point to be made for now is that the 
court held (at [38] of Yasain) that although Taylor 
was a civil case, the principles articulated therein were also relevant 
in the criminal context, and the Criminal Division of the English Court 
of Appeal likewise had the power to reopen a concluded criminal appeal. 
However, the court observed that this power would not be exercised in 
the same way in the criminal context because of the differences between 
civil and criminal cases, and opined that it would be best if a separate
 set of rules similar to those in r 52.17 of the English CPR could be 
formulated for criminal cases (at [40]). On the facts, the court held, 
applying Taylor, that the case before it was one where the appeal in question ought to be reopened.
33     Before
 we leave the English position, we should say a few words about the 
Criminal Cases Review Commission ("the CCRC”). The CCRC was set up in 
the wake of the public outcry over the conviction (and later 
exoneration) of the so-called "Birmingham Six” (see David Kyle, 
"Correcting Miscarriages of Justice: The Role of the Criminal Cases 
Review Commission” (2004) 52 Drake L Rev 657 at pp 660–662). It is an 
independent body which, although not itself able to quash convictions or
 reduce sentences (that remains the exclusive preserve of the courts), 
is nevertheless able to refer cases to the English Court of Appeal to be
 reheard in appropriate cases. Section 13(1) of the Criminal Appeal Act 
1995 (c 35) (UK) provides that a reference is not to be made unless:
(a)     the
 CCRC considers that "there is a real possibility that the [decision in 
question] would not be upheld were the reference to be made” (see 
s 13(1)(a)); and
(b)     the CCRC takes this view because of, inter alia,
 "an argument, or evidence, not raised in the proceedings which led to 
[the decision] or on any appeal or application for leave to appeal 
against it” (see s 13(1)(b)(i)); and
(c)     all
 avenues of appeal have already been exhausted, be it by the 
determination of an appeal or by the refusal of leave to appeal (see 
s 13(1)(c)).
In our view, this is very much in keeping with the raison d’ĂȘtre of the CCRC – it is intended only as a line of last defence to detect cases which would otherwise slip through the cracks.
Hong Kong
34     Until recently, the position in Hong Kong mirrored that which existed in England and Wales before Taylor.
 After the order of an appellate court in a criminal appeal (be it an 
order allowing the appeal or one dismissing it) had been perfected, the 
court could only reopen its decision and recall or vary its order if the
 order was a nullity or if there was a procedural error which had 
occasioned an injustice (see Secretary for Justice v Mak Wai Hon [2000] 1 HKC 498). However, in HKSAR v Tin’s Label Factory Ltd [2008] HKCU 1899, the Hong Kong Court of Final Appeal reviewed the developments that had taken place in England post-Taylor and remarked, obiter,
 that the approach adopted there "merits serious adoption in Hong Kong”,
 although it also cautioned that "the residual discretion is a wholly 
exceptional jurisdiction and the occasions when it may properly be 
invoked would be extremely rare” (at [56]).
35     In Brian Alfred Hall v HKSAR [2014] 4 HKC 500 ("Hall”),
 the Hong Kong Court of Final Appeal had to consider whether it had the 
power to reopen an appeal that had been allowed due to fraud on the part
 of the accused. The accused had earlier been convicted of common 
assault of prison officers after a trial in the Magistrates’ Court, and 
had been sentenced to six months’ imprisonment. On appeal, he adduced 
statements of certain prison officers which differed materially from the
 prosecution witnesses’ statements and their testimony at the trial. 
Upon production of those statements, the Prosecution conceded the appeal
 and the accused’s common assault conviction was quashed. Subsequently, 
it turned out that those statements had been forged on the accused’s 
instructions. The accused was then separately charged with four counts 
of perverting the course of justice, and sentenced to a total of six 
years and nine months’ imprisonment. Thereafter, the Prosecution applied
 to the Hong Kong Court of Final Appeal to reopen the appeal in respect 
of the accused’s common assault conviction with a view towards 
reinstating his conviction and sentence.
36     The Hong Kong Court of Final Appeal said at [11]:
…
 [I]t is clear that the court has an implied power exceptionally to 
order an appeal to be re-opened where justice so demands, such power 
being reasonably required for the effective exercise of the judicial 
power granted by the Basic Law.
The 
court emphasised that in deciding whether to exercise its power to 
reopen an appeal, it had to "take all relevant considerations into 
account” (at [12]). In particular, it was "necessary first to consider what purpose would be served by reopening the appeal”
 [emphasis added] (likewise at [12]). Given the already substantial 
sentence imposed on the accused for perverting the course of justice, 
the Hong Kong Court of Final Appeal held that reopening the appeal in 
respect of his common assault conviction would only have symbolic value,
 and that the judicial and public resources which would have to be spent
 were the appeal to be reopened would be wholly disproportionate to the 
object to be achieved. In the circumstances, the court declined to 
exercise its power to reopen the appeal.
Australia
37     In
 Australia, the approach is bifurcated. It has long been held that 
intermediate appellate courts (pertinently, for present purposes, the 
Courts of Criminal Appeal of the various Australian States) are unable 
to reopen a concluded appeal (see Burrell v R (2008) 248 ALR 428 ("Burrell”)
 at [22]). By contrast, where the High Court of Australia is concerned, 
it is now well established that it has the power "as the final national 
court of appeal, in exceptional circumstances, to repair its own 
mistakes and oversights that would otherwise occasion a serious and 
irremediable injustice, despite the fact that its orders have been 
formalised” (see Burrell at [105]). Given that only one tier of
 appeal is available in respect of criminal cases in Singapore, the 
distinction between intermediate and final appellate courts is not 
relevant, and we do not propose to dwell on it.
38     Although,
 as we have just mentioned, an intermediate appellate court in Australia
 has no power to reopen a concluded appeal, a further appeal against the
 court’s decision may lie if the High Court of Australia grants special 
leave for an appeal to be brought. That said, the High Court of 
Australia rarely grants such leave, and thus, the final avenue for 
review in a criminal matter usually lies in a petition for mercy (see R v GAM (No 2) [2004] VSCA 117
 at [11]). Legislative developments in some Australian States have, 
however, introduced a new dimension to the legal landscape. In 2013, the
 State of South Australia passed the Statutes Amendment (Appeals) Act 
2013 (No 9 of 2013) (SA) to insert a new s 353A into its Criminal Law 
Consolidation Act 1935 (SA) so as to provide accused persons with an 
opportunity for a "second or subsequent appeal” in limited 
circumstances. The relevant provisions of the new s 353A read:
(1)    The
 Full Court [of the Supreme Court of South Australia] may hear a second 
or subsequent appeal against conviction by a person convicted on 
information if the Court is satisfied that there is fresh and compelling evidence that should, in the interests of justice, be considered on an appeal.
(2)    A convicted person may only appeal under this section with the permission of the Full Court.
(3)    The Full Court may allow an appeal under this section if it thinks that there was a substantial miscarriage of justice.
…
[emphasis added]
39     Of
 particular interest are the definitions of "fresh” and "compelling” 
evidence in s 353A(6). In order to be "fresh”, the evidence in question 
must not have been adduced at the trial, and must be something which 
"could not, even with the exercise of reasonable diligence, have been 
adduced at the trial” (see s 353A(6)(a)). And in order to be 
"compelling”, the evidence concerned has to be "reliable”, "substantial”
 and "highly probative in the context of the issues in dispute at the 
trial of the offence” (see s 353A(6)(b)). In 2015, Tasmania passed the 
Criminal Code Amendment (Second or Subsequent Appeal for Fresh and 
Compelling Evidence) Act 2015 (No 41 of 2015) (Tas). Section 9 of that 
Act, which is modelled after the South Australian statute, likewise 
permits a second appeal to be brought (with leave) only if there is 
"fresh and compelling” evidence.
Malaysia
40     In Malaysia, in Dato’ See Teow Chuan & Ors and others v Ooi Woon Chee and others and other applications [2013] 4 MLJ 351,
 Arifin Zakaria CJ, delivering the unanimous judgment of the Federal 
Court of Malaysia, stated definitively that the Federal Court had the 
inherent power to review any matter already decided by the court where 
it was necessary "to do justice and to prevent an abuse of process” (at 
[10]). The court clarified that "[t]his power springs not from 
legislation but from the nature and constitution of the court as a 
dispenser of justice … [and] can only be taken away by express provision
 in any written law” (likewise at [10]). The court cautioned, however, 
that this power was to be exercised only in "special and exceptional” 
circumstances and could not be used as an avenue for a further appeal 
(at [15]).
41     Earlier, in Asean Security Paper Mills Sdn Bhd v Mitsui Sumitomo Insurance (Malaysia) Bhd [2008] 6 CLJ 1 ("Asean Security Paper Mills”),
 Abdul Hamid Mohamad CJ explained the difference between an application 
for a review and an appeal in the following way (at [4]):
In
 an application for a review by this court of its own decision, the 
court must be satisfied that it is a case that falls within the limited 
grounds and very exceptional circumstance in which a review may be made.
 Only if it does, that the court reviews its own earlier judgment. Under
 no circumstances should the court position itself as if it were hearing
 an appeal and decide the case as such. In other words, it is not for 
the court to consider whether this court had or had not made a correct 
decision on the facts. That is a matter of opinion. Even on the 
issue of law, it is not for this court to determine whether this court 
had earlier, in the same case, interpreted or applied the law correctly 
or not. That too is a matter of opinion. An occasion that I can think of
 where this court may review its own judgment in the same case on [a] 
question of law is where the court had applied a statutory provision 
that has been repealed. I do not think that review power should be 
exercised even where the earlier panel had followed certain judgments 
and not the others or had overlooked the others. Not even where the earlier panel had disagreed with the court’s earlier judgments. If
 a party is dissatisfied with a judgment of this court that does not 
follow the court’s own earlier judgments, the matter may be taken up in 
another appeal in a similar case. That is what is usually called 
"revisiting”. Certainly, it should not be taken up in the same case by 
way of a review. That had been the practice of this court all these
 years and it should remain so. Otherwise, there will be no end to 
litigation. A review may lead to another review and a further review. … 
[emphasis added]
42     Abdul 
Hamid Mohamad CJ then went on to give five non-exhaustive instances in 
which the Malaysian Federal Court’s power of review might be exercised. 
These included circumstances where the court was inquorate, where the 
applicant had been denied the right to be heard, where the decision had 
been procured by fraud, where the court had applied a law which had 
since been repealed, or where bias had been established (see Asean Security Paper Mills
 at [7]–[11]). These examples were endorsed by Zaki Tun Azmi PCA, who 
delivered the other reasoned judgment in that case. On the facts, the 
Malaysian Federal Court dismissed the application for review because it 
fell outside the limited scope of the court’s review jurisdiction.
Summary of the position in other jurisdictions
43     Gathering up the threads of the foregoing analysis, several propositions can be distilled:
(a)     First,
 a final appellate court has the inherent power, by virtue of its 
character as a court of justice, to correct its own mistakes in order to
 prevent miscarriages of justice or, to use a cognate expression 
favoured in England, "real injustice”.
(b)     Second,
 this power of review is to be exercised sparingly, and only in 
circumstances which can be described as "exceptional” and which 
therefore override the imperative of finality.
(c)     Third,
 a review by a final appellate court is distinct from and should not be 
confused with an appeal. In conducting a review, the court is primarily 
concerned not with the correctness of the decision under review, but 
with whether there has been a miscarriage of justice. These concepts are
 not the same. The paradigm case of a miscarriage of justice is where 
there has been a breach of natural justice.
(d)     Fourth,
 the substratum of an application for review should be new material that
 was not previously canvassed in the proceedings leading to the decision
 under challenge. The material in question must demonstrate a "powerful 
probability” that there has been a miscarriage of justice which warrants
 invoking the court’s review jurisdiction.
(e)     Finally,
 this power of review is available in both civil and criminal cases, 
although the rules governing its exercise might differ depending on the 
context.
A restatement of the Court of Appeal’s inherent power of review
44     Having
 reflected on the various tests which a final appellate court may adopt 
to decide whether it should review a case which has already exhausted 
the appeal process, we are satisfied that for a criminal matter, the 
general test enunciated by this court in Yong Vui Kong (Jurisdiction) at [15] – viz,
 that there must be "sufficient material on which the court can say that
 there has been a miscarriage of justice” – should be the touchstone 
where this court is concerned. In our view, this test captures pithily 
the essence of the five principles which we have distilled from the 
foreign cases and set out in the preceding paragraph. Analytically, we 
see this test as comprising two essential components:
(a)     The
 first is the evidential requirement of "sufficient material”. The court
 must be satisfied that the material adduced in support of the 
application for review is both "new” and "compelling” before it will 
consider the application. If the material presented does not satisfy 
these two indicia, then the application fails in limine and the inquiry stops there. The burden of production rests on the applicant.
(b)     The
 second is the substantive requirement that a "miscarriage of justice” 
must have been occasioned. This is the threshold which must be crossed 
before the court will consider that a concluded criminal appeal ought to
 be reopened. The burden of proving this likewise rests on the 
applicant.
45     We will 
examine each of these two components in detail below. But, before we do 
that, we think it important to identify and understand the policy 
tensions which operate in this area of the law.
Truth, finality and justice
46     The
 importance of truth in the criminal process is so axiomatic that it 
almost does not need to be stated. There is "searing injustice and 
consequential social injury … when the law turns upon itself and 
convicts an innocent person” (see Van Der Meer and Others v R (1998) 82 ALR 10 at 31 per
 Deane J). For this reason, criminal law accords primacy to the 
determination of the truth. But, the reality, and we do not shy away 
from admitting this, is that all human institutions are fallible, and 
any finding made by any court on a contested fact may be imperfect and 
may not necessarily arrive at the truth (see Lee Chez Kee v Public Prosecutor [2008] 3 SLR(R) 447 at [124]).
47     That
 said, this does not mean that society should stand paralysed with 
indecision, or that every legal finding must be open to continual 
challenge because of perpetual anxiety over the possibility of an error.
 The perfect, as they say, cannot be allowed to be the enemy of the 
good. Finality is also a function of justice. It would be impossible to 
have a functioning legal system if all legal decisions were open to 
constant and unceasing challenge, like so many tentative commas appended
 to the end of an unending sentence. Indeed, in the criminal context, 
challenges to legal decisions are very likely (and are also likely to be
 continuous and even interminable), given the inherently severe nature 
of criminal sanctions and the concomitant desire on the part of accused 
persons to avoid them as far as they can. The concern here is not just 
with the saving of valuable judicial resources (vital though that is), 
but also with the integrity of the judicial process itself. Nothing can 
be as corrosive of general confidence in the criminal process as an 
entrenched culture of self-doubt engendered by abusive and repetitive 
attempts to re-litigate matters which have already been decided.
48     The
 tension between truth and finality is a perennial one, and the key, as 
in so many other things, is balance. We cannot incline so much in favour
 of one that we neglect the other. As Kirby J observed in Burrell
 at [72], "we can love truth, like all other good things, unwisely; 
pursue it too keenly; and be willing to pay for it too high a price, so 
we can also love finality too much”. Truth and finality are both vital, 
and their competing demands must be held in balance. In The Ampthill Peerage [1976] 2 WLR 777, Lord Wilberforce put it in these terms (at 786H–787B):
…
 Any determination of disputable fact may, the law recognises, be 
imperfect: the law aims at providing the best and safest solution 
compatible with human fallibility and having reached that solution it 
closes the book. The law knows, and we all know, that sometimes fresh 
material may be found, which perhaps might lead to a different result, 
but, in the interest of peace, certainty and security it prevents 
further enquiry. It is said that in doing this, the law is preferring 
justice to truth. That may be so: these values cannot always coincide. 
The law does its best to reduce the gap. But there are cases where the 
certainty of justice prevails over the possibility of truth … and these 
are cases where the law insists on finality. For a policy of closure to 
be compatible with justice, it must be attended with safeguards …
49     The
 question for us in the present context is whether we have struck the 
right balance between the prevention of error (which demands some degree
 of corrigibility) and the according of proper respect to the principle 
of finality (which necessitates a policy of closure). It is axiomatic 
that this balance will have to be struck differently at different stages
 of the criminal process. As we venture further along the criminal 
process, we must give greater presumptive weight to the veracity of the 
findings already made and accord greater prominence to the principle of 
finality. An appeal is an avenue for error correction. For this reason, 
in an appeal, the decision of the trial court must be examined for 
error, but due deference must be accorded to that court’s findings, and 
new evidence cannot be admitted, save in limited circumstances. A review
 is an avenue for the correction of miscarriages of justice. Thus, it is
 only in exceptional cases that a matter will be reopened on its merits,
 and the instances in which the Court of Appeal’s inherent power of 
review will be exercised must be few and far between.
50     In
 our judgment, the principle of finality is no less important in cases 
involving the death penalty. There is no question that as a modality of 
punishment, capital punishment is different because of its 
irreversibility. For this reason, capital cases deserve the most anxious
 and searching scrutiny. This is also reflected in our laws. Division 1A
 of Part XX of the Criminal Procedure Code (Cap 68, 2012 Rev Ed) ("the 
CPC”) provides that a sentence of death imposed by the High Court has to
 be reviewed by the Court of Appeal even where no formal appeal has been
 filed, and the court must be satisfied of the correctness, legality and
 propriety of both the accused person’s conviction and his sentence 
before the sentence is carried into effect. But, once the processes of 
appeal and/or review have run their course, the legal process must 
recede into the background, and attention must then shift from the legal
 contest to the search for repose. We do not think it benefits anyone – 
not accused persons, not their families nor society at large – for there
 to be an endless inquiry into the same facts and the same law with the 
same raised hopes and dashed expectations that accompany each such 
fruitless endeavour.
51     Against
 this background of competing considerations, we now turn to the first 
component of the test set out at [44] above for determining when it is 
appropriate for this court to exercise its inherent power of review – viz, the evidential requirement of "sufficient material”.
The evidential requirement of "sufficient material”
52     When may it be said that there is "sufficient material” (which, in this context, encompasses both
 new factual evidence as well as new legal arguments) to warrant the 
Court of Appeal exercising its inherent power of review? In our 
judgment, for the material tendered in support of an application for 
review to be "sufficient”, it must satisfy two cumulative conditions: 
(a) it must be "new”; and (b) it must be "compelling”. Collectively, 
these conditions form a fine mesh filter that sieves out unmeritorious 
applications for review while allowing justice to be done in deserving 
cases. We will examine each condition in turn below.
(1)   The material must be "new”
53     "New”
 material is that which: (a) has hitherto not been considered at any 
stage of the proceedings leading to the decision under challenge; and 
(b) could not, even with reasonable diligence, have been adduced in 
court prior to the filing of the application for review. In adopting 
this position, we align ourselves with the approach taken in South 
Australia, where the presence of "fresh” evidence is a jurisdictional 
precondition that must be satisfied before "a second or subsequent 
appeal” may be brought (see [39] above and also R v Keogh (No 2) [2014] SASCFC 136 at [98]). The difference is that in our context, we accept that new legal arguments can – if they satisfy the twofold criteria stated at the outset of this paragraph (viz, of not having been considered at an earlier stage of the proceedings and
 of being material which could not, even with reasonable diligence, have
 been presented to the court before the filing of the application for 
review) – form the basis for an application for review.
54     The first limb of the requirement of "new” material – viz,
 that the material must be something which has previously not been 
considered – is a corollary of the fact that a review is neither an 
appeal nor a rehearing. As has been emphasised in many of the cases 
cited above, the purpose of a review is to correct a miscarriage of 
justice, and not to allow the applicant a second chance to rehash the 
same issues in the hope of achieving a different outcome. If the 
applicant is relying solely on evidence and/or legal arguments that have
 already been put forward (in the hope that the court will change its 
mind at the second time of asking), then the application for review, 
without more, cannot succeed. In order to justify this court’s exercise 
of its inherent power of review, the material tendered in support of the
 application must be genuinely novel – it will not suffice if that 
material is merely old wine in new wineskins. The applicant cannot 
merely seek to put a new spin on old evidence which has already been 
considered by the court or take a new position on material which has 
already been analysed by the court.
55     The second limb of the requirement of "new” material – viz,
 that the material must be something which could not, even with 
reasonable diligence, have been obtained for use prior to the filing of 
the application for review – is familiar to us as the Ladd v Marshall [1954] 1 WLR 1489
 requirement of "non-availability”. There are two reasons for this. 
First, it seems to us that if an accused has of his own volition not 
called evidence which was available to him and which, bearing in mind 
his circumstances as an accused (including the fact that he might have 
been in remand), he could reasonably have been expected to obtain and 
adduce in court, then there cannot be any basis for saying that there 
has been a miscarriage of justice. The accused must accept the 
consequences of his decision as to the calling and treatment of evidence
 (see Ratten v The Queen (1974) 131 CLR 510 at 517–518 per
 Barwick CJ). Second, it is in the wider public interest that there be 
an efficient and economical allocation of court resources. Parties who 
come before the court (and this includes accused persons) must present 
all their evidence at the time of the hearing in order that it may be 
properly weighed and evaluated, instead of introducing their evidence in
 a piecemeal and haphazard fashion.
56     At this point, a comparison with applications to admit additional evidence in criminal appeals is instructive. In Soh Meiyun v Public Prosecutor [2014] 3 SLR 299 ("Soh Meiyun”),
 the High Court favoured a less restrictive approach towards the 
admission of further evidence in criminal appeals. It stated that an 
appellate court exercising criminal jurisdiction "should generally hold 
that additional evidence which is favourable to the accused person and 
which fulfils the Ladd v Marshall conditions of relevant and reliability is ‘necessary’ and admit such evidence on appeal” (at [16]).
57     There is, however, a crucial difference between the scenario in Soh Meiyun and that in the Present Application – namely, the former concerned an appeal against a first-instance decision, whereas the Present Application (and other similar applications for review) is a post-appeal
 application. The wastage of judicial resources that would accompany the
 reopening of a case which has already been decided on its merits (which
 the requirement of non-availability is designed to prevent) is 
therefore concomitantly greater. For this reason, we are of the view 
that greater stringency is warranted in an application for a review of a
 concluded criminal appeal, and the requirement of non-availability must
 be strictly adhered to in respect of such an application.
58     We
 appreciate that this means that it will be rare for this court to 
entertain an application for review which is premised on new legal 
arguments alone because it will normally be difficult for the applicant 
in such a case to show that the legal arguments in question could not, 
even with reasonable diligence, have been raised prior to the filing of 
the application for a review. It seems to us that in respect of new 
legal arguments, the criterion of "non-availability” will ordinarily be 
satisfied only if the legal arguments concerned are made following a 
change in the law (for examples of "change in the law” cases, see Regina v Cottrell and another appeal [2007] 1 WLR 3262 at [42]–[46] and Regina v Jogee and another appeal [2016] 2 WLR 681). We also observe that this is the position taken in civil proceedings in relation to the so-called "Arnold exception” to issue estoppel (see Arnold v National Westminster Bank plc [1991] 2 AC 93 ("Arnold”)). In Arnold,
 Lord Keith of Kinkel held that there should be an exception to issue 
estoppel "in the special circumstance that there has become available to
 a party further material relevant to the correct determination of a 
point involved in the earlier proceedings”, provided that the further 
material in question "could not by reasonable diligence have been 
adduced in those [earlier] proceedings” (at 109B). As we emphasised in TT International
 at [189] and [190(c)], the "further material” in question must be 
material which shows that "the error in the court’s decision stemmed 
from some point of fact or law relevant to the decision [which] was not 
taken or argued before the court which made that decision and could not reasonably have been taken or argued on that occasion” [emphasis in original]. In Arnold,
 the "further material” consisted of subsequent judicial decisions 
which, Lord Keith held, could "not inappositely be described as a change
 in the law” (see Arnold at 109C).
(2)   The material must be "compelling”
59     "Compelling”
 material is that which is reliable, substantial and powerfully 
probative; it must be capable of showing almost conclusively that there 
has been a miscarriage of justice (see [31] and [39] above). The 
threshold is a high one. In Yong Vui Kong (Jurisdiction), 
Chan CJ gave the following examples of the kind of material which he 
considered might justify the exceptional recourse of a review (at [14]):
It is not uncommon in other jurisdictions, such as the United States, for new exculpatory evidence to be discovered, eg, DNA evidence which
 can show almost conclusively that the blood found at the scene of the 
crime or on the body of the deceased (in murder cases) was not that of 
the accused. There may be other types of evidence which could have the same effect, eg, new documentary evidence which was not discovered during the trial or the appeal. … [emphasis added in italics and bold italics]
60     There
 are two dimensions to the requirement that the material in question 
must be "compelling”. First, the material must be "reliable” in the 
sense that it possesses a high degree of cogency, and is credible and 
trustworthy in respect of the matters to which it pertains. It is 
notable that all the examples given by Chan CJ in Yong Vui Kong (Jurisdiction) at [14]–[15] related to material of an objective character: eg,
 DNA evidence, documentary evidence or a new line of authorities. The 
reason for this is that objective evidence is quintessentially reliable 
since, in general, it may be independently verified and is based on 
facts which may be apprehended by analysis, measurement and observation.
 While we would not go so far as to dogmatically exclude all subjective 
evidence, we would imagine that such evidence would not ordinarily 
suffice to show "almost conclusively” that a miscarriage of justice has 
been occasioned. Thus, evidence from witnesses who have taken the stand,
 particularly that of co-accused persons who now seek to resile from 
their earlier testimony (see, eg, Abdullah), cannot in itself be considered "reliable” evidence unless it is substantiated by other objective evidence.
61     The
 second dimension of the requirement of "compelling” material is that 
the material in question must be "substantial” and "powerfully 
probative” in the sense that it is logically relevant to the precise 
issues which are in dispute. The mere fact that material is reliable 
does not necessarily mean that it is relevant. For example, the presence
 of a person’s DNA on an object is almost conclusive evidence of the 
fact that that person touched the object. However, that piece of 
information might be of little or no utility in determining whether that
 person committed the crime in question. This applies with even greater 
force to new lines of legal argument. The imposition of criminal 
punishment almost invariably involves the deprivation of life and 
liberty, and therefore, by definition, Art 9(1) of the Constitution, 
which provides that "[n]o person shall be deprived of his life or 
personal liberty save in accordance with law”, is tangentially involved 
in all criminal cases. But, it does not follow that Art 9(1) will be 
relevant in every criminal case. Much will depend on the precise issues 
which fall to be decided on the facts of the case.
62     At
 the end of the day, the inquiry into whether the material tendered in 
support of an application for review is "compelling” is directed towards
 the quality of the material presented as assessed against the precise 
issues in dispute. A useful summative question is whether, taken as a 
whole, the material is capable of showing "almost conclusively” that 
there has been a miscarriage of justice, and is therefore "compelling” 
enough to warrant the exercise of the Court of Appeal’s inherent power 
of review. This is a question of fact which calls for an exercise of 
judgment of the kind that judges are called on to perform on an almost 
daily basis.
The substantive requirement of a "miscarriage of justice”
63     We
 turn now to the substantive requirement that a "miscarriage of justice”
 must have been occasioned (see [44(b)] above). The expression 
"miscarriage of justice” is one of those protean expressions that is 
incapable of an exhaustive and stipulative definition. At its core, it 
connotes that there must be a manifest error and/or an egregious 
violation of a principle of law or procedure which strikes at the very 
heart of the decision under challenge and robs it of its character as a 
reasoned judicial decision. Based on our survey of the cases, a 
miscarriage of justice is chiefly (but not exclusively) to be found in 
one of the following two situations:
(a)     The
 first is where a decision on conviction or sentence is "demonstrably 
wrong”. In this regard, it is not sufficient to show that there is a 
real possibility that the decision is wrong; instead, it must be shown 
that there is a powerful probability that it is wrong. Generally, this 
plea may be raised only by the accused and not by the 
Prosecution, save in an exceptional case where the Prosecution has 
uncovered material new evidence which it seeks to rely on to set aside 
an unsafe conviction or an excessive sentence premised on a fundamental 
misapprehension of the applicable law or facts.
(b)     The
 second situation is where there has been fraud or a breach of natural 
justice. This arises where, in the words of Dame Elizabeth in Uddin at [18], there has been a "corruption
 of justice” [emphasis in original], such that the integrity of the 
judicial proceedings itself has been impugned. An application for a 
review on this ground is available to both the Prosecution and the 
accused.
We will discuss each of these situations in turn below.
(1)   Where the decision on conviction or sentence is "demonstrably wrong”
64     There is no doubt that the conviction of an innocent person is an injustice – perhaps the
 ultimate substantive injustice, proof of which would justify reopening a
 concluded criminal appeal. However, as we have discussed at [46]–[48] 
above, absolute certitude is never available. This is so even in the 
case of DNA evidence, the utility of which is highly context-specific. 
The question, therefore, is: how certain does the court have to be that 
its previous decision (be it on conviction or sentence) is wrong before 
it decides to reopen a matter? In Yong Vui Kong (Jurisdiction) at [14], Chan CJ opined that an appropriate test was whether the decision in question was "demonstrably found to be wrong” [emphasis added].
65     In
 our judgment, where the decision under challenge is a decision on 
conviction, it is not sufficient to show that there is a real 
possibility that the decision is wrong. Instead, it must be shown, based
 on the material tendered in support of the application for review alone
 and without the need for further inquiry, that there is a powerful 
probability that the decision concerned is wrong. There are two reasons 
for this rigorous standard. First, the higher standard properly 
distinguishes the function of an appeal, which is a means for the 
correction of error, from that of a review, which is about the 
protection of the integrity of the judicial process. This point was 
amply made in Uddin and Asean Security Paper Mills. 
Second, it would better vindicate the importance of the principle of 
finality by allowing intervention only in truly exceptional cases. This 
approach accords due recognition to the fact that the decision under 
challenge has already undergone at least two rounds of separate and 
independent scrutiny – once by the court exercising original criminal 
jurisdiction and another by the Court of Appeal in its appellate 
capacity – and these courts’ findings must be given great presumptive 
weight. Such findings should only be displaced where they can be proved 
to be "demonstrably wrong”.
66     Where
 the decision under challenge is a decision on sentence, given that 
sentencing involves an exercise of discretion, it will be even more 
difficult for the applicant to demonstrate that the decision concerned 
is "demonstrably wrong”. It would not be sufficient for the applicant 
merely to allege that the sentence imposed is manifestly excessive, or 
that the court failed to appreciate the material before it, or even that
 the court relied on the wrong test or the wrong precedent. These are 
the standards for intervention applicable to an appeal (see Public Prosecutor v Mohammed Liton Mohammed Syeed Mallik [2008] 1 SLR(R) 601 ("Mohammed Liton”)
 at [82]). In our judgment, in order for a decision on sentence to be 
considered "demonstrably wrong”, the applicant would have to show that: 
(a) the decision was based on some fundamental misapprehension 
of the law or the facts, thereby resulting in a decision that can, 
without exaggeration, be described as blatantly wrong; and (b) the error
 must be plain on the face of the record. We venture to think that 
instances of this nature will be exceedingly rare. It may occur, for 
example, where the court imposed a sentence in excess of its sentencing 
jurisdiction (see, eg, Public Prosecutor v Louis Pius Gilbert [2003] 3 SLR(R) 418), where it failed to impose the statutorily-prescribed punishment (see, eg, Public Prosecutor v Loo Kun Long [2003] 1 SLR(R) 28) or, conversely, where it imposed a sentence above the statutorily-prescribed maximum (see, eg, Chiaw Wai Onn v Public Prosecutor [1997] 2 SLR(R) 233).
67     An
 application for a review on the ground that a decision, whether on 
conviction or sentence, is "demonstrably wrong” is usually available 
only to the accused and not to the Prosecution (see [63(a)] above). This
 is because when the State prosecutes a criminal matter, it wields an 
awesome power. Therefore, it has concomitant interests and duties which 
are not simply those borne by an ordinary litigant (see TT International at [128]). One corollary of this is that once a person has been acquitted of an offence, the doctrine of autrefois acquit
 prevents him from being tried again for the same offence (see Art 11(2)
 of the Constitution). The purpose of this doctrine is to protect 
individuals from oppression, and to allow accused persons who have had 
their cases disposed of to move on with their lives without fear that 
they will once again be subject to the machinery of criminal justice in 
respect of the same offence (see Regina v Humphrys [1976] 2 WLR 857 at 877B per
 Lord Hailsham of St Marylebone). In our judgment, this principle is 
equally applicable to an application for a review even though, strictly 
speaking, no "retrial” might be involved. Thus, even if the Prosecution 
is of the view that an acquittal is unjustified or that a sentence, 
being based on a fundamental misapprehension of the law or the facts, is
 unjustifiably lenient, it would still be absolutely precluded from 
applying for a review of the decision.
68     Conversely, however, if the Prosecution elects to bring an application for a review in the accused’s favour (eg,
 to set aside an unsafe conviction or an excessive sentence premised on a
 fundamental misapprehension of the applicable law or facts), then it 
would not be precluded from doing so. As the High Court observed (albeit
 in a slightly different context) in Public Prosecutor v Lim Choon Teck [2015] 5 SLR 1395,
 the Public Prosecutor has a crucial role to play in the fair and 
impartial administration of criminal justice. To this end, it should be 
able to correct egregious errors in the judicial process by bringing the
 appropriate applications for review where necessary.
(2)   Where there has been fraud or a breach of natural justice
69     Where
 the decision under challenge has been tainted by fraud or a breach of 
natural justice which has an adverse effect on the accused, that alone –
 even in the absence of proof that the decision is "demonstrably wrong” –
 would usually suffice to establish that a miscarriage of justice has 
been occasioned. This was the position in England even pre-Taylor
 (see [26] above), and it is also the position taken in all the 
jurisdictions which we surveyed. We give three illustrative examples 
below:
(a)     In R v Daniel,
 the applicant pleaded guilty to burglary and was sentenced to 
18 months’ imprisonment. Before a sole judge, he sought leave to appeal 
against his sentence out of time, but was unsuccessful. He then renewed 
his application for leave to appeal, this time before the Full Court, 
and engaged counsel for this purpose. However, due to an administrative 
oversight, his counsel were not informed of the hearing, and the English
 Court of Appeal heard and dismissed his leave application in the 
absence of counsel. When this oversight was discovered, counsel sought 
to have the application re-listed for hearing. However, the English 
Court of Appeal, holding itself to be functus officio, 
dismissed the application. The Secretary of State then intervened and 
referred the matter back to the English Court of Appeal for a rehearing 
pursuant to the powers given to him under s 17 of the Criminal Appeal 
Act 1968 (c 19) (UK). At the restored hearing of the application for 
leave to appeal, the court acknowledged that it had initially acted per incuriam
 in holding that it had no jurisdiction to rehear the matter, but 
stressed that even in such a case, a matter would be re-listed for 
hearing only if it could be shown that there was a likelihood of 
injustice.
(b)     In Ramanathan a/l Chelliah v Public Prosecutor [2009] 6 MLJ 215,
 the applicant was convicted by the trial court of two counts of 
outraging the modesty of the victim. His conviction was later quashed by
 the Malaysian High Court on two grounds: excessive delay on the part of
 the trial court in rendering written reasons, and an error of law on 
the applicable standard of proof. The Prosecution appealed to the 
Malaysian Court of Appeal and only those two points were argued. The 
court agreed with the Prosecution and, without first giving the 
applicant an opportunity to resist the appeal, reinstated the 
conviction. On an application for a review, a differently-constituted 
Malaysian Court of Appeal held that the applicant’s right to a fair 
hearing had been violated and ordered that the appeal be reheard.
(c)     In Regina v Bow Street Metropolitan Stipendiary Magistrate and Others, ex parte Pinochet Ugarte (No 2) [1999] 2 WLR 272,
 the House of Lords set aside one of its own decisions on the ground of 
apparent bias. The applicant, a former head of state, had been arrested 
pursuant to international warrants which alleged the commission of 
various crimes against humanity. When the matter came before the House 
of Lords for the first time, the validity of the international arrest 
warrants was upheld despite the argument that the applicant enjoyed 
sovereign immunity. Subsequently, it transpired that one of the law 
lords in the panel had links with a party involved in the proceedings. 
That factor alone – even in the absence of any indication of actual bias
 – was held to be a sufficient basis for a rehearing to be ordered.
70     An application for a review on the ground of fraud or breach of natural justice is available to both
 the Prosecution and the accused (see [63(b)] above) because of the 
wider public interest considerations involved. Where a decision in an 
individual criminal case is wrong, the impact on the public interest is 
comparatively limited. Consequently, the public interest in the 
reopening of the case (even where the decision might arguably be 
"demonstrably wrong”) is outweighed by the policy considerations in 
favour of finality in litigation, as well as the compelling interest in 
protecting an accused person from double-prosecution. However, where 
considerations of fraud or natural justice are involved, public 
confidence in the integrity of the very criminal justice process itself 
is at stake, and this suffices to outweigh the considerations of 
finality and the protection of an accused from double prosecution.
71     This
 does not necessarily mean, however, that the court will treat an 
application for a review from the Prosecution in the same manner as it 
does an application from an accused person: ie, that the application will be granted almost as a matter of course. On this point, a comparison between Yasain and Hall is instructive.
72     In Yasain,
 the accused had earlier been convicted of a number of offences 
including rape and kidnapping. The sentences imposed for the rape charge
 (six years) and the kidnapping charge (one and a half years) had been 
ordered to run consecutively, making a cumulative sentence of seven and a
 half years’ imprisonment. When the accused appealed, it was noticed 
that no verdict had been recorded in respect of the kidnapping charge 
even though the accused had been sentenced on it. The English Court of 
Appeal therefore ordered that the conviction in respect of the 
kidnapping charge be expunged. Subsequently, it was discovered that a 
verdict on the kidnapping charge had in fact been returned by the jury, 
but had not been recorded because of an error. The Prosecution then 
applied for the court to reopen the appeal and reinstate the accused’s 
conviction and sentence in respect of the kidnapping charge. The 
application was allowed because the error had resulted in an unwarranted
 18-month reduction in the accused’s sentence. The court observed that 
what had taken place was the product of "a rare coincidence of 
circumstances”, and that the "very substantial public interest in those 
properly convicted serving the sentence imposed” justified the 
extraordinary recourse of reopening the appeal (at [49]).
73     By contrast, in Hall,
 it will be recalled that the accused had already been sentenced to 
nearly seven years’ imprisonment for perverting the course of justice, 
whereas the sentence which he had received for assaulting prison 
officers, which had been set aside because of the fraud that he 
perpetrated, was only six months’ imprisonment (see [35]–[36] above). 
The Hong Kong Court of Final Appeal noted that should the appeal 
pertaining to the accused’s common assault conviction be reopened, much 
time and resources would have to be devoted to its disposal. The court 
concluded that such an expenditure of resources would not be justified, 
given that the interests of justice had already been served by the 
imposition of a separate and lengthy custodial sentence on the accused 
for perverting the course of justice, and thus, there was no need to 
reopen the appeal. It seems to us that the reason given by the Hong Kong
 Court of Final Appeal for not reopening the appeal makes good practical
 sense. That said, we have not heard the Public Prosecutor on this 
question as the issue did not arise in the present case, and we 
therefore express no concluded view on it.
A clarification: new legal arguments involving constitutional points
74     As
 a final point before we conclude our discussion of when it is 
appropriate for the Court of Appeal to reopen its decision in a 
concluded criminal appeal, we think it is important to clarify this 
court’s earlier comments in Ramalingam (at [17]) and Quek Hock Lye
 (at [23]–[24]) that the criminal motions in those cases were heard 
because they concerned new legal arguments involving constitutional 
points in relation to capital offences. In our judgment, Ramalingam and Quek Hock Lye
 should be confined to their facts. Both were cases in which this court 
saw the need to clarify important legal points in the public interest. 
These two cases should not be interpreted to mean that there is an 
automatic right of review whenever new legal arguments involving 
constitutional points are raised in a capital case. Indeed, it is 
evident that in Ramalingam, this court did not think that the 
raising of new legal arguments involving constitutional points was in 
itself a sufficient ground for a review. At [16], it noted that the 
applicant had had ample opportunity to raise, at an earlier stage, the 
constitutional points which he now sought to advance in his application 
for review, and therefore "could have had no cause to complain if we had declined to hear this Motion
 on the basis that he had exhausted all his rights to due process …” 
[emphasis added]. We would clarify that the touchstone, at the end of 
the day, is still whether the applicant has produced sufficient material
 upon which the court may conclude that there has been a miscarriage of 
justice. For the purposes of determining if this test has been 
satisfied, it does not matter, where the material relied on consists of 
new legal arguments, whether or not those legal arguments involve 
constitutional points – the same criteria still apply.
75     This can be seen most clearly in Yong Vui Kong (Prosecutorial Discretion).
 The issue in that case was whether the applicant’s constitutional right
 to equal treatment had been violated by the Public Prosecutor’s 
decision to charge him but not one "Chia”, who was alleged to be the 
kingpin of the drug syndicate for which the applicant worked. (Chia was 
detained under the provisions of the Criminal Law (Temporary Provisions)
 Act (Cap 67, 2000 Rev Ed) instead.) The applicant argued, on the basis 
of the principles articulated in Ramalingam (which was decided 
just two weeks prior to the filing of his application for review), that 
the Court of Appeal should reopen its decision on his conviction and 
sentence (in Yong Vui Kong v Public Prosecutor [2010] 3 SLR 489).
 In explaining why it decided to reconsider the matter even though no 
novel constitutional points were involved, the court said that the case 
presented itself as a more compelling instance in which there might have
 been unequal treatment since Chia "appear[ed] to be a more culpable 
offender than [the applicant]” (see Yong Vui Kong (Prosecutorial Discretion)
 at [19]). Further, the court noted that the issue of possible unequal 
treatment was one which had arisen solely as a result of its decision in
 Ramalingam, and therefore, the argument was "new” both in the 
sense that it had hitherto never been considered before the filing of 
the application for review and could not, even with reasonable 
diligence, have been raised in court prior to that (see likewise Yong Vui Kong (Prosecutorial Discretion) at [19]). Thus presented, it can be seen that the court applied the usual criteria (viz,
 the production of sufficient material to establish that there has been a
 miscarriage of justice) in deciding whether to entertain the 
application, even though the material relied on by the applicant 
consisted of new legal arguments involving constitutional points.
76     To
 reiterate, the raising of hitherto unconsidered points of 
constitutional law is not in itself sufficient to show that the Court of
 Appeal ought to review a concluded criminal appeal. Much would depend 
on the merits of the constitutional points concerned and whether they 
would, having regard to the factual context of the case in question, 
affect the outcome of the case and thus show that a miscarriage of 
justice has been occasioned. We would reiterate that litigants who pray 
in aid of the Court of Appeal’s inherent power to reopen a concluded 
criminal appeal must show that there is sufficient material upon which it may be concluded that there has been a miscarriage of justice.
Summary of the applicable legal principles
77     This
 concludes our discussion on the law relating to the Court of Appeal’s 
inherent power of review. From this, the following key propositions can 
be distilled:
(a)     The 
Court of Appeal, as the final appellate court in Singapore, has the 
inherent power to reopen a concluded criminal appeal in order to prevent
 a miscarriage of justice. This power is a facet of the judicial power 
which is vested in the Court of Appeal by virtue of Art 93 of the 
Constitution. When the court exercises this power of review, it is 
acting within the scope of its statutorily-conferred appellate 
jurisdiction, which is not completely exhausted merely by the rendering 
of a decision on the merits of the appeal.
(b)     A
 review of a concluded criminal appeal is not to be confused with an 
appeal. In reviewing a case, the Court of Appeal is primarily concerned 
not with the correctness of the decision under review, but with the 
question of whether there has been a miscarriage of justice. To justify 
the exercise of the court’s inherent power of review, the applicant must
 satisfy the court that there is sufficient material on which it may 
conclude that there has been a miscarriage of justice. In this regard, 
the mere fact that the material relied on by the applicant consists of 
new legal arguments involving constitutional points does not, without more, suffice.
(c)     In
 deciding whether to exercise its inherent power of review, the Court of
 Appeal will consider the following two matters (as set out at 
sub-paras (d) and (e) below).
(d)     The
 first is whether the applicant has discharged his burden of producing 
"sufficient material” to warrant the court exercising its inherent power
 of review. The material put forward must possess two signal features in
 order to be considered "sufficient”: (i) it must be "new” – ie,
 it must not previously have been canvassed at any stage of the 
proceedings prior to the filing of the application for review, and it 
must be something which could not, even with reasonable diligence, have 
been adduced in court earlier; and (ii) it must be "compelling” – ie,
 it must be reliable, substantial, powerfully probative, and therefore, 
capable of showing almost conclusively that there has been a miscarriage
 of justice.
(e)     The 
second condition is whether the applicant has discharged his burden of 
proving that there has been a "miscarriage of justice”. Generally, the 
court will only find that there has been a "miscarriage of justice” in 
one of the following two situations:
(i)       The
 first is where a decision of the court on conviction or sentence is 
shown to be "demonstrably wrong”. In relation to a decision on 
conviction, it is not sufficient for the applicant to show that there is
 a real possibility that the decision concerned is wrong; instead, it 
must be apparent, based on the evidence tendered in support of the 
application alone and without the need for further inquiry, that there 
is a powerful probability that the decision is wrong. In relation to a 
decision on sentence, it must be shown that the decision under challenge
 was based on some fundamental misapprehension of the law or the facts, 
thereby resulting in a decision that is blatantly wrong on the face of 
the record. An application for a review on the ground that a decision 
(whether on conviction or sentence) is "demonstrably wrong” is usually 
available only to the accused.
(ii)       The
 second scenario is where the decision under challenge is tainted by 
fraud or a breach of natural justice, such that the integrity of the 
judicial process is compromised. An application for a review on the 
ground of fraud or breach of natural justice is available to both the 
accused and the Prosecution.
Should this court’s decision in CA (Re-sentencing) be reopened?
78     In
 our judgment, applying the legal principles which we have just outlined
 to the Present Application, this application is misconceived in 
principle and must fail. For the most part, the Applicant merely 
traverses the same grounds as those which he covered in his submissions 
before this court at the hearing of CA (Re-sentencing). There 
is very little in the way of "new” material, let alone material which is
 "compelling” and which justifies the exceptional recourse of a review. 
The Applicant has never suggested that there was any fraud, and in his 
amended notice of motion, the allegation that there was a breach of 
natural justice has been dropped. It has always been his core case in 
the Present Application that this court’s decision in CA (Re-sentencing)
 was wrong; but, as will be plain from our analysis of the evidence, he 
fell short of showing that the sentence which this court imposed was 
"wrong”, let alone "demonstrably wrong”. In truth, the Present 
Application is not a genuine application for a review, but an attempt to
 re-litigate a matter which had already been fully argued and thoroughly
 considered.
79     Given the 
acute importance of this case to the Applicant and his family, and 
because this is the first time we have articulated the principles 
governing the exercise of the Court of Appeal’s inherent power of 
review, we propose to examine the material which the Applicant has put 
forward in some detail. However, we must clarify that, moving forward, 
such a detailed analysis will not be appropriate in every application 
for review, particularly where it is clear that the application is 
plainly without merit. We are doing so in this case only for 
illustrative purposes.
The grounds relied on by the Applicant
80     In
 his submissions, counsel for the Applicant, Mr Mohan, has laid out a 
number of "grounds” in support of his argument that there is a need for 
this court to exercise its inherent power to reopen its decision in CA (Re-sentencing). For ease of exposition, we will refer to each of these "grounds” as "Ground 1”, "Ground 2”, and so on.[note: 7]
 As there is some degree of overlap in the various "grounds”, we have 
merged and reorganised them into four principal contentions. Broadly 
summarised, Mr Mohan argues that this court’s decision in CA (Re-sentencing):
(a)     was premised on an error of law;
(b)     was based on the wrong factual premise;
(c)     breached the requirement of unanimity; and
(d)     breached the Applicant’s right to a fair trial.
We will deal with each of these principal contentions in turn below.
Was the decision in CA (Re-sentencing) premised on an error of law?
81     Mr Mohan’s
 first principal contention, which embraces Grounds 1, 2, 6 and 7 of his
 submissions, is that this court erred in law in sentencing the 
Applicant to death. As a preliminary point, Mr Mohan first argues that 
the Prosecution has no right of appeal against a sentence of life 
imprisonment and caning imposed by the High Court (in lieu of a sentence
 of death) pursuant to an application for re-sentencing under the 2012 
Amendment Act, and for that reason, this court acted without 
jurisdiction in CA (Re-sentencing) when we substituted the 
death sentence in place of the sentence of life imprisonment and 24 
strokes of the cane imposed by the Re-sentencing Judge.[note: 8]
 Apart from this jurisdictional argument, Mr Mohan also submits that 
this court’s decision was wrong in law for the following reasons:
(a)     There was no basis for appellate intervention in CA (Re-sentencing) because the sentence imposed by the Re-sentencing Judge was not manifestly inadequate.[note: 9]
(b)     The test applied by this court to decide whether a sentence of death should be imposed – viz, whether the actions of the offender would "outrage the feelings of the community” (also referred to hereafter as "the CA (Re-sentencing)
 test” where the context so warrants) – is not appropriate for the 
offence of murder. In relation to this offence, Parliament’s intention 
is that a wide ambit of considerations, and not only those relating to 
the circumstances of the offence, should be taken into account to 
determine the appropriate sentence.[note: 10]
(c)     The
 imposition of a sentence of death offends the principle of consistency 
since there are cases, both decided before and after CA (Re-sentencing), which are more serious than the Applicant’s case, but which did not attract the death penalty.[note: 11]
No right of appeal
82     It is important to remember that CA (Re-sentencing)
 was the Prosecution’s appeal against sentence. Therefore, based on the 
principles we have articulated above, in order for a review to lie, the 
Applicant needs to show that this court’s decision in that appeal was 
based on a "fundamental misapprehension” of the applicable law or facts 
and was therefore "blatantly wrong”. Of all the arguments raised by 
Mr Mohan in support of his first principal contention, the only one that
 could conceivably satisfy this standard is the argument that this court
 acted without jurisdiction in CA (Re-sentencing) because the Prosecution had no right of appeal against the decision in HC (Re-sentencing).
 In our judgment, however, this argument is plainly without merit. The 
relevant provisions of s 4(5) of the 2012 Amendment Act in this regard 
read as follows:
Where on the appointed day,
 the Court of Appeal has dismissed an appeal brought by a person for an 
offence of murder under section 302 of the Penal Code, the following 
provisions shall apply:
…
(h)    the
 provisions of Division 1 of Part XX of the Criminal Procedure Code 
relating to appeals shall apply to any appeal against the 
[re-sentencing] decision of the High Court under paragraph (g) 
with the modification that any appeal must be lodged by the appellant 
with the Registrar of the Supreme Court within 14 days after the date of
 the re-sentencing by the High Court …
…
83     Division 1
 of Part XX of the CPC relates to appeals, and s 374(3), which falls 
within it, states that the Public Prosecutor may appeal against "the 
acquittal of an accused or the sentence imposed on an accused or an order of the trial court” [emphasis added]. The purport of s 4(5)(h)
 of the 2012 Amendment Act (read with Division 1 of Part XX of the CPC) 
is that the sentence passed by the High Court upon an application for 
re-sentencing is to be treated as if it were the sentence originally 
passed by the High Court following the accused person’s trial. Such a 
decision is undoubtedly appealable, and there is nothing in either the 
2012 Amendment Act or the CPC which indicates that the decision is final
 and non-appealable. The Public Prosecutor submitted – and we agree – 
that it is plain and obvious that the High Court’s decision in a 
re-sentencing application is to be treated like any other sentencing 
decision made by the High Court in the exercise of its original criminal
 jurisdiction, and is therefore appealable to this court.[note: 12] In light of the foregoing, we hold that this court did have the jurisdiction to hear CA (Re-sentencing).
84     The
 remaining errors of law which the Applicant alleged had occurred do not
 really warrant any serious consideration and do not even come close to 
establishing that this court committed a blatant error in CA (Re-sentencing).
 This alone is sufficient to dispose of Mr Mohan’s first principal 
contention; but, for completeness, we will go on to discuss briefly 
below each of the "grounds” which Mr Mohan has advanced under this 
particular contention.
No basis for appellate intervention
85     In Mohammed Liton at [81]–[82], we explained that appellate courts would intervene to correct sentences in one of the following four situations:
(a)     where the sentencing judge erred in respect of the proper factual basis for the sentence;
(b)     where the sentencing judge failed to appreciate the material before him;
(c)     where the sentence was wrong in principle; or
(d)     where the sentence was, in all the circumstances, manifestly excessive or manifestly inadequate.
Mr Mohan’s submission that "the Court of Appeal can only increase the sentence where the original penalty imposed was manifestly inadequate”[note: 13] [emphasis in original omitted; emphasis added in italics] is therefore clearly incorrect.
86     This court’s decision in CA (Re-sentencing)
 is justifiable on at least two of the four aforementioned bases for 
appellate intervention. First, it may be said that the Re-sentencing 
Judge erred in respect of the proper factual basis for the sentence. At 
[58]–[59] of CA (Re-sentencing), the majority of this court 
noted that the Re-sentencing Judge erred in holding that there was 
insufficient evidence to conclude that the Applicant had approached the 
deceased from behind. That the Applicant had indeed done so was a 
finding which the minority accepted as well (see CA (Re-sentencing) at [91]–[103]). Second, it may be said that the Re-sentencing Judge erred on a matter of principle. The cases of Sia Ah Kew v Public Prosecutor [1974–1976] SLR(R) 54 and Panya Martmontree v Public Prosecutor [1995] 2 SLR(R) 806 were both cited to him (see HC (Re-sentencing) at [13]–[14]), but he did not adopt the test articulated therein: viz, that a sentence of death would be appropriate where the offence outraged the feelings of the community. In CA (Re-sentencing),
 this court unanimously adopted that test as the correct legal test for 
determining whether it would be appropriate to impose the death sentence
 for the offence of murder. Accordingly, the Re-sentencing Judge’s 
decision was erroneous as a matter of principle.
Wrong test applied
87     Before us, Mr Mohan argued impassionedly that the test which this court unanimously endorsed and applied in CA (Re-sentencing) in determining whether the Applicant ought to be sentenced to death – viz,
 whether his actions "outrage the feelings of the community” (at [44], 
[86] and [203]) – was wrong. According to Mr Mohan, this test should be 
confined in its application to only the offence of kidnapping, in 
respect of which it was originally promulgated. He submits that it is 
too blunt a test in the context of the offence of murder because all 
instances of murder, by definition, involve violence and result in 
death, and are bound to outrage the feelings of the community. Thus, to 
apply this test to the offence of murder would be to consign all persons
 convicted of murder to death. Mr Mohan also criticises this test for 
its inflexibility, arguing that it permits the sentencing court to 
consider only the manner in which the offence was committed, but not the
 accused’s motives or concerns of general deterrence.[note: 14]
 In lieu of this test, Mr Mohan suggests, we should adopt the position 
taken by the Indian Supreme Court and the courts of some of the 
Caribbean States: viz, that the death penalty should be reserved for cases which are the "rarest of the rare”.[note: 15]
88     In
 our view, this argument does not even begin to get off the ground. The 
points made by Mr Mohan, including the Indian and the Caribbean 
authorities to which he referred, had been considered extensively by 
this court in CA (Re-sentencing) (at [38]–[43]) and are clearly
 not "new”. This court had carefully reviewed those points and those 
authorities, and had given reasons for rejecting the Indian and the 
Caribbean approach. We do not propose to reprise the analysis here.
89     More
 troubling, however, is the fact that Mr Mohan appears to have 
completely misunderstood what the test of whether the offender’s actions
 "outrage the feelings of the community” involves. This test does not 
entail that the court is to sentence by public opinion, with the 
sentence of death being imposed for the offence of murder whenever a 
preponderance of the members of the public express sufficient distaste 
for the accused’s actions. We completely abjure such a 
suggestion. That is not the way this court or, for that matter, any 
court elsewhere would administer justice. The test that this court 
adopted in CA (Re-sentencing) sets out, instead, a reasoned normative standard
 which future courts are to apply when deciding whether to impose the 
death penalty for the offence of murder. At [44], this court said:
In our judgment, a more appropriate principle to follow would be that laid down by the Court of Appeal in Sia Ah Kew [v Public Prosecutor [1974–1976] SLR(R) 54], which is, whether the actions of the offender would outrage the feelings of the community. Undoubtedly,
 capital punishment is an expression of society’s indignation towards 
particularly offensive conduct, and the fact that the death penalty 
continues to be part of our sentencing regime is an expression of 
society’s belief that certain actions are so grievous an affront to 
humanity and so abhorrent that the death penalty may, in the face of 
such circumstances, be the appropriate, if not the only, adequate 
sentence. It would therefore, in our judgment, be correct to 
consider the strong feelings of the community in deciding whether or not
 to impose the death penalty. [emphasis in original in italics; emphasis
 added in bold italics]
90     Determining
 whether an offender’s actions so "outrage the feelings of the 
community” and are "so grievous an affront to humanity and so abhorrent”
 that the death penalty is justified is an exercise in ethical judgment 
in which the sentencing court expresses the collective conscience of the
 community through the selection of a condign punishment. In performing 
this exercise, contrary to what Mr Mohan submitted, the remit of the 
sentencing court’s inquiry is not circumscribed. This court specifically stated in CA (Re-sentencing) that the sentencing court was to look widely, and that "all
 the circumstances and factors of the case must be taken into 
consideration in meting out an appropriate sentence” [emphasis added] 
(at [37]), thus also ensuring that the inquiry would be an objective
 one. Furthermore, at [51(d)], this court expressly highlighted that 
"the motive and intention of the offender at the time he committed the 
offence” was an important sentencing factor which must form part of the 
sentencing matrix. In the circumstances, we see no warrantable basis for
 concluding that this court applied the wrong test in CA (Re-sentencing).
Inconsistency in sentencing
91     In
 support of his argument based on inconsistency in sentencing (see 
[81(c)] above), Mr Mohan tendered a diagram in which he arranged five 
cases in ascending orders of severity.[note: 16] These cases are: Public Prosecutor v Kamrul Hasan Abdul Quddus [2014] SGHC 4, Public Prosecutor v Gopinathan Nair Remadevi Bijukumar (Criminal Case No 40 of 2011),[note: 17]Public Prosecutor v Ellary bin Puling and another (Criminal Case No 40 of 2009),[note: 18]Public Prosecutor v Wang Wenfeng [2014] SGHC 23 and Public Prosecutor v Micheal Anak Garing and another [2015] SGHC 107 ("Micheal Garing”)
 (a case involving two offenders). Of the six offenders sentenced in 
these five cases, only one received the death penalty; the rest received
 terms of life imprisonment and between ten and 24 strokes of the cane. 
Mr Mohan argued that the Applicant’s case was less serious than two 
others in which the death penalty was not imposed, and was therefore not
 one which should attract the death penalty.
92     The material which Mr Mohan relied on is not new. All the cases mentioned in the preceding paragraph, save for Micheal Garing, which was decided only after CA (Re-sentencing), had already been cited to this court in argument at the hearing of CA (Re-sentencing) and were fully considered.[note: 19]
 We will not delve into the details of these cases, save to say that 
they do not give us any further reasons to conclude that this court’s 
decision to impose the sentence of death in CA (Re-sentencing) 
was, on the basis of the principle of consistency in sentencing, 
"blatantly wrong”. By its very nature, sentencing is a fact-sensitive 
exercise in judicial discretion which involves balancing a myriad of 
considerations (see Mohammed Liton at [81]). To arrange cases along a "spectrum” necessarily involves making a value judgment on the importance of some factors vis-Ă -vis
 others. This is an exercise in respect of which even reasonable persons
 may differ. For this reason, it would ordinarily be very difficult to 
demonstrate that a sentencing decision is "blatantly wrong” on the basis
 of inconsistency alone, and we certainly do not think that such an 
argument can sensibly be maintained in the present case, given that this
 court had already considered the aforesaid precedent cases (except for Micheal Garing).
Was the decision in CA (Re-sentencing) based on the wrong factual premise?
93     Mr Mohan’s
 second principal contention, which comprises Grounds 3, 4 and 5 of his 
submissions, is that this court erred in imposing the sentence of death 
in CA (Re-sentencing) as it based its decision on incorrect 
findings of fact. The thrust of Mr Mohan’s argument in this regard is 
that the majority erred in relying on the findings made in CA (Conviction)
 – which, he submits, are open to serious question – to hold that the 
Applicant assaulted the deceased multiple times from the back.[note: 20]
 Mr Mohan argues that the question of whether the Applicant struck the 
deceased at least three times from the back is critical because the 
sentence of death would not be justified if it cannot be proved
 that the Applicant was the one who caused the majority of the 
deceased’s skull fractures. He contends that the proper interpretation 
of the evidence is that "there were at least 2 blows caused by the Applicant (one sufficient to fracture the skull), however, there could have been more” [emphasis in original].[note: 21]
94     In
 our judgment, this argument is a non-starter because the point is not 
new, and had already been thoroughly considered and analysed in CA (Re-sentencing).
 But, before we explain our reasons for rejecting this argument, we 
think it is necessary to address an important preliminary point. This 
concerns Mr Mohan’s contention that at the hearing of CA (Re-sentencing), this court ought, of its own motion, to have remitted the matter to the High Court for further evidence to be taken at a Newton hearing (see R v Robert John Newton
 (1982) 4 Cr App R (S) 388) in order to clarify the alleged 
"ambiguities” relating to the manner in which the Applicant attacked the
 deceased. Mr Mohan argues that a Newton hearing was necessary because the sentence of death which this court imposed in CA (Re-sentencing)
 was premised on an assessment of the Applicant’s culpability made on 
the basis of facts which the Applicant did not have an adequate 
opportunity to challenge either at first instance (in HC (Conviction)) or on appeal (in CA (Conviction)) as those facts were not relevant then since the death penalty was mandatory for the offence of murder at the time.[note: 22]
Should this court have remitted the matter for a Newton hearing?
95     We think it is important to set the record straight. The short answer to the question as to why this court did not, in CA (Re-sentencing), order a Newton
 hearing to be convened is simply this: the Applicant elected not to 
lead further evidence. Before the Re-sentencing Judge, the Applicant 
(through his then counsel, Mr Anand Nalachandran and Mr Josephus Tan) 
consistently maintained that he did not think further evidence needed to
 be led, nor did he wish to make the requisite application to do so. The
 following two exchanges took place during the hearing of the 
Applicant’s re-sentencing application. The first exchange was between 
Mr Nalachandran and the Re-sentencing Judge:[note: 23]
| 
Court: | 
… [I]f you look at [CA (Conviction)] …, they seem to set out various versions but I don’t see any exact finding as to what was the exact sequence of events. | 
| 
… |  | 
| 
Court: | 
… [N]one of you were involved in the defence – at the trial, right? | 
| 
Nalachandran: | 
No, Sir. None of us was in the trial for the [Applicant]. | 
| 
Tan: | 
No. | 
| 
Court: | 
Okay.
 So I don’t suppose I can derive much help from you insofar as what were
 the exact findings of [the trial judge] or the Court of Appeal, other 
than what appears on record. | 
| 
Nalachandran: | 
Sir, I think for the purposes of this [re]- sentencing, we are – | 
| 
Court: | 
Sorry. Could you just turn the mic to your side? | 
| 
Nalachandran: | 
Sorry, Sir. Perhaps
 for the purposes of this [re]-sentencing hearing, I think we are 
limited by the findings in the judgments of the High Court and the Court
 of Appeals [sic]. | 
[emphasis added]
The second exchange was between Mr Tan and the Re-sentencing Judge:[note: 24]
| 
Tan: | 
Your
 Honour, if I may move on to the point of intoxication. … I found this 
information on the internet. This is a island-wide recall notice by the 
AVA dated 26th of August 2009. And Your Honour, if we look at the dates,
 that were –actually means that prior to this recall, that alcohol – 
that particular brand of alcohol consumed by the five accused person[s] 
contained excessive methanol which will cause alcohol poisoning, and of 
course, the effects of alcohol poisoning, we have already put it in our 
written submissions, dizziness, blurr[ing] of the vision – | 
| 
Court: | 
But that would contradict the findings of the trial [j]udge as well as the affirmation by the Court of Appeal, right? | 
| 
Tan: | 
Yes, Your Honour. All this information [was] not available then at both instances. | 
| 
Court: | 
 But you are not suggesting further evidence now, are you? Or you are just saying?  | 
| 
Tan: | 
 No, Your Honour, we are not. We are – we are not disturbing –  | 
| 
Court: | 
 You are just asking me to extrapolate, right?  | 
| 
Tan: | 
 Yes, Your Honour. We are just saying that – | 
[emphasis added]
96     Mr Mohan’s submission that the two exchanges quoted above on the leading of further evidence concerned only the question of whether the Applicant was intoxicated at the time he attacked the deceased is incorrect.[note: 25] As is clear from the first extract, the fact in issue during the first exchange was the exact sequence of events relating to the assault,
 and it was in relation to that precise question that the Applicant’s 
then counsel accepted that he was limited by the findings which had 
already been made by the High Court in HC (Conviction) and by the Court of Appeal in CA (Conviction).
 While it is true that the second exchange took place in relation to the
 defence of intoxication, read in context, it is clear that the 
Applicant’s then counsel accepted that he was bound by the findings made
 in CA (Conviction), and therefore, as a general point, did not
 seek to introduce further evidence. Of course, it was always open to 
the Applicant to change his mind when the Prosecution appealed against 
the Re-sentencing Judge’s decision, and he could have made the requisite
 application at the hearing of CA (Re-sentencing) to adduce 
further evidence, but he did not do so. Given the way that events have 
developed, it does not, in our judgment, lie in the Applicant’s mouth to
 now say that this court ought to have intervened and ordered a Newton hearing to be held.
97     As
 a matter of principle, the court should not descend into the arena and 
instruct parties on the proper way to conduct their case. That is not 
the way our adversarial system works. In all cases, and crucially in 
criminal cases, the role of the court is to maintain a posture of 
impartiality and approach the matter disinterestedly. There are times 
when the court must step in to ensure that justice is done, particularly
 where an accused person is conducting his defence without the aid of 
counsel. But, where an accused person is represented, it is not for the 
court to question or second-guess the decisions which he makes upon the 
advice of his counsel. The court would also not know what further 
evidence an accused person might adduce. Had this court directed, in CA (Re-sentencing), that a Newton
 hearing be carried out, and had the result of the inquiry been 
unfavourable to the Applicant, we can well imagine that this court would
 now be faulted for having intervened instead of not having intervened.
The number of blows inflicted by the Applicant
98     As
 we said at [94] above, none of the material cited by Mr Mohan in 
support of his argument that the Applicant inflicted only two blows on 
the deceased is "new”. The material presented – chiefly, the allegedly 
inconclusive nature of the medical evidence relating to the number of 
blows inflicted on the deceased’s head – was before this court at the 
hearing of CA (Re-sentencing), and was carefully considered by both the majority (at [63]–[68]) and the minority (at [124]–[126] per Lee Seiu Kin J; and at [151]–[152] per
 Woo Bih Li J). While the majority and the minority may have reached 
divergent conclusions, there is no basis for suggesting that the 
material in question was not adequately argued by counsel and examined 
by this court.
99     A further problem with this argument is that it rests on the incorrect premise that the majority in CA (Re-sentencing) had concluded that the sentence of death was warranted only because the Applicant had inflicted at least three blows on the deceased’s head. That was not in fact the position. The majority never thought that the number of blows – while certainly relevant – was decisive. In CA (Re-sentencing), those in the majority said:
63    In our opinion, the
 exact number of blows that the [Applicant] inflicted on the deceased 
and the manner in which they were carried out while certainly relevant 
to our inquiry are not necessarily decisive. …
…
71    We
 have focused thus far on the exact number of blows the [Applicant] had 
inflicted on the head of the deceased, although that is not the defining
 question that needs to be answered. The key question which we must 
answer is – did the [Applicant] act in a manner which showed a blatant 
disregard for human life? While, as we have stated above, … the question
 as to the number of blows which the [Applicant] had landed on the head 
of the deceased is not decisive, it remains very relevant to the key 
question. The following considerations are critical to our decision:
(a)    First,
 we find that the [Applicant] had approached the deceased from behind, 
and struck him without any warning. Whether or not this was prefaced 
with a struggle, between Galing [the Applicant’s co-accused] and the 
deceased, is of little significance to the [Applicant]’s culpability. After the first blow was inflicted which caused the [deceased] to fall to the ground, there was effectively no more struggle.
(b)    Second, after
 the deceased fell to the ground after the first blow and then turned 
around to face upwards, the [Applicant] struck him once more. It is not 
disputed that the [deceased] was not retaliating. …
(c)    In any case, even
 if the [Applicant]’s assertion that he had only struck the deceased 
twice is to be believed and accepted, … the force he exerted in the two 
blows must have been so great as to cause fracturing of such severity 
and magnitude, so much so that a fall, or a strike with Galing’s belt buckle, could have caused further fracturing.
…
78    … Even
 if we were to accept the position that it was unclear as to how many 
times the [Applicant] had struck the head of the deceased, what is vitally important to bear in mind is that what we have here was a completely shattered skull. Bearing in mind the fact that the alleged intention of the [Applicant] and Galing was merely to rob the deceased, what the [Applicant] did underscores the savagery of the attack which was characterised by needless violence that went well beyond the pale.
[emphasis in original omitted; emphasis added in italics and bold italics]
100    Read
 fairly and in its proper context, it is clear from the above extract 
that even if the Applicant’s account had been accepted, and even if the 
majority had proceeded on the basis that the Applicant had struck the 
deceased only twice on the head (see CA (Re-sentencing) at [60]), the majority would still have concluded that the sentence of death was warranted. The three critical factors which the majority relied on in deciding to impose the death penalty were the following:
(a)     the
 Applicant first struck the deceased from behind on the head without 
warning, causing the latter to fall to the ground (at [71(a)]);
(b)     the
 Applicant inflicted at least one more blow on the deceased while the 
latter was laying on the ground defenceless (at [71(b)]); and
(c)     even
 if only two blows had been inflicted on the deceased by the Applicant, 
it would be fair to infer that the two blows must have been of such 
force that they caused extensive fractures to the deceased’s skull and 
weakened it to the extent that the strike with the belt buckle by the 
Applicant’s co-accused, Galing, and/or the deceased’s fall onto the 
ground caused further fractures when, ordinarily, they would not have 
done so (at [67]–[68], [71(c)] and [78]).
To the majority, these factors alone
 were cumulatively sufficient to justify the conclusion that the 
Applicant had evinced "a blatant disregard for human life” and therefore
 ought to be sentenced to death (at [77]–[79]). Thus, even if the 
majority had been wrong to conclude that the Applicant had inflicted at 
least three blows on the deceased’s head, there is no basis for saying 
that the sentence of death which this court imposed in CA (Re-sentencing) constituted a miscarriage of justice because it was premised on an incorrect finding of fact.
101    We acknowledge that those in the minority in CA (Re-sentencing)
 disagreed. While the minority agreed that the Applicant had struck the 
deceased from behind (see [86] above) and had inflicted at least two 
blows on the deceased, which caused the latter’s skull to fracture (at 
[199] per Lee J; and at [215] per Woo J), unlike the 
majority, they did not think that these factors were sufficient to 
warrant the imposition of the death penalty. In the minority’s opinion, 
the threshold would only have been crossed if it could be concluded that
 the Applicant had inflicted three or more blows on the deceased which, 
alone, were responsible for the multiple fractures of the latter’s skull
 (at [200]–[201] per Lee J; and at [217] per Woo J). 
In a similar vein, Mr Mohan argued that the death penalty would only be 
justified if the multiple fractures found on the deceased’s head "were 
caused by multiple blows and … it was the Applicant who caused the 
majority of the fractures by those multiple blows”.[note: 26]
102    What
 this shows is that sentencing is an intensely difficult exercise, and 
that reasonable persons can, and often do, disagree as to what the 
appropriate sentence ought to be. That is why a wide margin of 
appreciation is given to sentencing judges called on to exercise their 
discretion. In our judgment, the mere fact of disagreement among the 
members of the coram is not sufficient to justify this court exercising 
its inherent power of review. The test for the purposes of the Present 
Application is whether the decision in CA (Re-sentencing) was 
"blatantly wrong”. Neither those in the majority nor those in the 
minority even came close to suggesting that the other side’s decision 
was "blatantly wrong”, and Mr Mohan has not presented us with any "new” 
evidence, let alone that which is "compelling”, which justifies our 
arriving at a contrary conclusion today. In the final analysis, there is
 no basis for us to exercise our inherent power of review on the ground 
that this court’s decision in CA (Re-sentencing) was based on an incorrect factual premise.
Did the decision in CA (Re-sentencing) breach the requirement of unanimity?
103    The
 third principal contention raised by Mr Mohan, which corresponds to 
Grounds 8 and 10 of his submissions, is that the imposition of the death
 penalty on the Applicant in CA (Re-sentencing) was unconstitutional because the decision to impose that penalty was not unanimous.[note: 27]
 In this regard, Mr Mohan first points to Art 9(1) of the Constitution, 
which provides that "[n]o person shall be deprived of his life or 
personal liberty save in accordance with law”. In its seminal decision 
in Ong Ah Chuan and another v Public Prosecutor [1979–1980] SLR(R) 710 ("Ong Ah Chuan”),
 the Privy Council held that the word "law” in Art 9(1) referred to a 
system of law incorporating those "fundamental rules of natural justice”
 that had formed part of the common law of England before the commencement of the Constitution (at [26] per
 Lord Diplock). For this reason, the Board stated, the effect of 
Art 9(1) was that there could be no deprivation of life or personal 
liberty – even if sanctioned by written law – if such deprivation were 
to offend a fundamental rule of natural justice.
104    Mr Mohan
 submits that one fundamental rule of natural justice is that a sentence
 of death may not be imposed except by a unanimous verdict. This, he 
contends, is a common law rule of ancient vintage commented on by (inter alia) Sir William Blackstone (see Commentaries on the Laws of England: Book the Fourth (A Strahan, 16th Ed, 1825) at p 349), Sir James Fitzjames Stephen (see A History of the Criminal Law of England (MacMillan and Co, 1883) vol 1 at pp 304–305) and Lord Devlin (writing extra-judicially in Trial by Jury
 (Steven & Sons Ltd, 1956) ch 3 at p 56). When our laws still 
provided for criminal trials by jury, this rule was embodied in s 211 of
 the Criminal Procedure Code (Cap 132, 1955 Rev Ed), which stipulated 
that a verdict of guilty (in all cases, and not just capital cases) 
could only be returned by the jury either: (a) unanimously; or (b) by a 
majority of 5:2, with the concurrence of the presiding judge. After 
criminal trials by jury were abolished in 1971, the requirement of 
unanimity still applied in capital cases in that offenders facing 
capital charges were tried by two judges, both of whom had to agree on 
the offender’s guilt in order for there to be a conviction (see s 185(2)
 of the Criminal Procedure Code (Cap 113, 1970 Rev Ed)).[note: 28]
 This requirement was abolished only when the Criminal Procedure Code 
(Amendment) Act 1992 (Act 13 of 1992) came into effect on 18 April 1992.
105    The
 modern manifestation of this rule, Mr Mohan argues, is that if the High
 Court elects not to impose a sentence of death, this court can reverse 
the High Court’s decision and substitute a sentence of death if and only if it acts unanimously.[note: 29]
 To the extent that s 31(1) of the SCJA (and to this, we may add 
s 386(3) of the CPC) states that an appeal is to be decided in 
accordance with the opinion of the majority of the judges on the coram, 
Mr Mohan submits that this should not apply to an appeal against the 
imposition of a capital sentence.[note: 30]
Analysis of the Applicant’s arguments
106    The alleged rule of natural justice which Mr Mohan has raised (viz,
 that a decision to impose the death penalty in a capital case must be 
unanimous) is a point which arose only as a result of this court’s 
decision in CA (Re-sentencing). For that reason, the arguments 
and authorities which Mr Mohan has raised in this regard are new in the 
sense that they had previously not been considered and could not, even 
with the exercise of reasonable diligence, have been considered prior to
 the filing of the Present Application. However, the critical question 
is whether, together, these arguments and authorities establish a 
"compelling” case that a miscarriage of justice has been occasioned. In 
our judgment, they do not. We give two reasons for this conclusion.
107    First,
 the authorities cited by Mr Mohan, even taken at their highest, do not 
stand for the proposition that the decision of an appellate judicial body
 must likewise be rendered unanimously in order for a sentence of death 
to be imposed. At best, they stand for the proposition that a decision 
on conviction rendered by a body of lay jurors considering a capital charge at first instance
 must be unanimous. The fact that there was, historically, a requirement
 for unanimity in capital trials conducted by lay jurors does not in any
 way suggest that it should likewise be an essential requirement for appeals
 heard by professional judges. In fact, Mr Mohan accepts that this is as
 far as the authorities go. However, he also submits that the broader 
point is that, as a matter of principle, the imposition of capital 
punishment must always be attended by procedural safeguards, one of 
which is that the trial must be conducted by jury and that the jury must
 decide the matter unanimously.[note: 31]
108    Putting
 aside for the moment Mr Mohan’s argument that a trial by jury is an 
essential safeguard for capital cases (with which we do not agree), it 
still does not provide any reason why unanimity is required in appellate
 hearings presided over by professional judges. Mr Mohan was unable to 
point us to any single jurisdiction which requires its appellate courts 
to decide criminal cases by unanimous decision. Even during the period 
when criminal trials were conducted by jury in Singapore, an appeal
 from the decision of the jury, which was heard by the then Court of 
Criminal Appeal, was decided in accordance with the opinion of the majority
 and did not have to be unanimous (see s 3(5) of the Court of Criminal 
Appeal Ordinance (Cap 129, 1955 Rev Ed)). Since the abolition of 
criminal trials by jury, this court has affirmed convictions in capital 
cases by a majority (see, eg, Took Leng How v Public Prosecutor [2006] 2 SLR(R) 70).
 In our judgment, therefore, the so-called common law rule of unanimity 
in capital cases, to the extent that it continues to exist, is confined 
in its operation only to trials conducted by juries consisting of laypersons, and does not extend to criminal appeals heard by an appellate court made up of professional judges.
109    Our
 second reason for rejecting Mr Mohan’s submissions on the aforesaid 
rule of unanimity is that we are not persuaded that this rule, to the 
extent that it even exists, can be considered a fundamental rule of 
natural justice. In Yong Vui Kong v Public Prosecutor [2015] 2 SLR 1129
 (a case concerning the constitutionality of the sentence of caning), we
 explained that the fundamental rules of natural justice referred to by 
the Privy Council in Ong Ah Chuan were "procedural rights aimed at securing a fair trial” [emphasis in original] (at [64]). In other words, they are universal
 rules which apply at all times and cannot be abrogated, even by 
Parliament. The Applicant has not shown why the requirement of unanimity
 in capital cases is such a rule.
110    In Robert Apodaca et al v Oregon
 406 US 404 (1972) at 409, Powell J noted that there were four main 
explanations for the historical requirement of unanimity in criminal 
cases. These explanations are summarised in Raoul G Cantero and Robert 
M Kline, "Death is Different: The Need for Jury Unanimity in Death 
Penalty Cases” (2009–2010) 22 St Thomas L Rev 4 ("Cantero and Kline”) at p 29 as follows:
First,
 hundreds of years ago, the criminal justice system lacked many of the 
procedural safeguards afforded today. Second, courts performed trials by
 compurgation [with matters being decided based on whether a party could
 assemble the requisite number of sworn witnesses testifying to his good
 character], in which the court added to the original number of 12 
compurgators until one party had 12 compurgators on its side. 
Supposedly, when the courts abandoned this approach, the requirement 
remained that one side had to obtain the votes of all twelve jurors. 
Third, unlike modem juries, those in medieval times consisted of jurors 
who had personal knowledge of the facts. The medieval mind believed 
there could be only one correct answer to a conflict, which meant there 
was no place for reasonable jurors to disagree. If reasonable jurors 
cannot disagree, the only correct verdict must, necessarily, be a 
unanimous one. Fourth, the medieval concepts of consent required juries 
to render unanimous verdicts. The very word "consent” connoted 
unanimity. Evidence exists that in the 14th century, Parliament could 
not bind the community or individual members to a legal decision unless 
the members of Parliament unanimously rendered the decision. Only in the
 15th century, when unanimity became increasingly harder to obtain, did 
Parliament begin to allow majority decisions.
111    From
 this brief summary, it may be concluded that the so-called rule of 
unanimity is too particular and too idiosyncratic to the jury system as 
it originated in medieval England to be considered a universal rule of 
criminal law for all capital offences, wherever and howsoever 
prosecuted. As Lord Diplock clarified at [27] of Ong Ah Chuan, 
observance of the fundamental rules of natural justice "does not call 
for the perpetuation in Singapore of technical rules … [which] are 
largely a legacy of the role played by juries in the administration of 
criminal justice in England as it developed over the centuries”. In 
fact, we would go further to say that we do not think the rule of 
unanimity should even apply to modern criminal jury trials, let alone 
criminal trials presided over by professional judges. We note that since
 the passage of the Criminal Justice Act 1967 (c 80) (UK), English 
juries have been permitted to return verdicts by majority decision 
(including, prior to the abolition of capital punishment in the United 
Kingdom in 1988, in capital cases involving offences such as espionage 
and treason).
112    In the 
final analysis, even if the so-called rule of unanimity exists, it would
 not, in our judgment, come within the ambit of the fundamental rules of
 natural justice. Therefore, Parliament is free to derogate from this, 
as it did when it allowed majority verdicts to be returned in capital 
cases (see [104] above). We therefore hold that the Applicant’s 
contention on this ground affords no compelling basis for us to exercise
 this court’s inherent power of review.
Did the decision in CA (Re-sentencing) breach the Applicant’s right to a fair trial?
113    The
 fourth and final principal contention raised by Mr Mohan, which may be 
found in his post-hearing written submissions, is that the Applicant’s 
right to a fair trial was infringed in CA (Re-sentencing) when 
this court substituted the sentence of life imprisonment and caning 
imposed by the Re-sentencing Judge with one of death. This argument is 
framed in two ways:
(a)     First,
 the Applicant was disadvantaged because he did not have the benefit of 
conducting his defence at the trial in light of the considerations 
articulated in the test which this court adopted in CA (Re-sentencing)
 in deciding whether to impose the death sentence on him. If the 
Applicant had known of this test at the time of his trial, he might have
 presented his evidence differently, and might consequently have escaped
 the death penalty. The situation is doubly unfair in the Applicant’s 
case because future offenders who are charged with murder would have a 
better chance of escaping the death penalty than the Applicant in that 
they would now know the test which the court would apply at the 
sentencing stage to determine whether the death penalty ought to be 
imposed, whereas the Applicant did not.[note: 32]
(b)     Second, the Re-sentencing Judge’s decision in HC (Re-sentencing)
 to sentence the Applicant to life imprisonment and 24 strokes of the 
cane (in lieu of the death sentence originally imposed by the trial 
judge) amounted to an "acquittal” of the Applicant from the death 
penalty. Thus, this court breached the rule against double jeopardy when
 it allowed the Prosecution’s appeal against the sentence imposed by the
 Re-sentencing Judge and substituted the death penalty in its stead.[note: 33]
 Furthermore, it was argued that following the decision of the 
Re-sentencing Judge, the Applicant had a "legitimate expectation” that 
he would not be sentenced to death.[note: 34]
114    Like
 the third principal contention advanced by Mr Mohan, the issue which 
Mr Mohan has raised here is one which arose only as a result of this 
court’s decision in CA (Re-sentencing). While the Applicant’s 
arguments on this fourth principal contention are new, we do not think 
they provide a compelling basis for concluding that there has been a 
miscarriage of justice as far as the Applicant is concerned. We now turn
 to examine each of these arguments in turn.
The Applicant did not know the test which would be applied
115    Addressing,
 first, the argument that the Applicant was disadvantaged because he did
 not have the benefit of conducting his defence at the trial with 
knowledge of the contours of the test which this court applied in CA (Re-sentencing)
 to determine whether the death penalty ought to be imposed, we 
understand Mr Mohan’s argument to proceed in the following way. At the 
time the Applicant was tried, the number of blows which he had inflicted
 on the deceased, the force with which he had delivered those blows and 
the cause of the multiple fractures of the deceased’s skull were not 
relevant. Since the death penalty was mandatory for the offence of 
murder at that time, liability for murder and, as a corollary, the death
 sentence would have been attracted so long as it could be established 
that the Applicant had intended to inflict the injuries which led to the
 deceased’s death. That the Applicant had intended to inflict those 
injuries was not in doubt as he had admitted to striking the deceased 
twice. Thus, the Applicant did not have any impetus to adduce evidence 
of his own (whether by way of expert testimony or otherwise) at his 
trial to challenge the Prosecution’s account of how the attack on the 
deceased had taken place. However, following the passage of the 2012 
Amendment Act and our subsequent decision in CA (Re-sentencing),
 where this court set out the applicable test for determining whether it
 would be appropriate to impose the death penalty for the offence of 
murder, the details of the attack on the deceased became critical.[note: 35] In the circumstances, it was inherently unfair for this court to impose the death penalty on the Applicant in CA (Re-sentencing) because, as Mr Mohan put it:[note: 36]
…
 [T]here remains the real possibility that, had the nuances of the test 
been known [at the time the Applicant was tried], the evidence would 
have come out differently. So long as that possibility exists, the 
Applicant has been denied a fair hearing. …
116    We
 accept that at the time the Applicant was tried, the precise details of
 the attack on the deceased were not relevant, and, for that reason, no 
findings on this issue were made in either HC (Conviction) or CA (Conviction) (see CA (Re-sentencing)
 at [54] and [63]). We also accept that whenever an accused is charged 
with having committed murder within the meaning of ss 300(b)–300(d) of the PC (for which the death penalty is now discretionary, rather than mandatory), the manner
 of the attack on the victim is now a matter of first importance as it 
would have a crucial impact on whether the accused is sentenced to life 
imprisonment and caning or to death. Further, we are willing to assume 
that accused persons who are charged with murder within the meaning of 
ss 300(b)–300(d) would now be mindful of the need to 
lead evidence relating to the precise manner in which the attack in 
question took place, for it would have a vital bearing on the eventual 
sentence that is imposed.
117    However,
 we do not think it follows from this that there has therefore been a 
miscarriage of justice in the present case. If the Applicant’s argument 
were accepted, it would mean that all accused persons who were 
re-sentenced pursuant to the 2012 Amendment Act after the conclusion of 
their trial for murder could likewise argue that they suffered a 
disadvantage at the re-sentencing stage because there was a 
"possibility” that they might have presented their evidence differently 
at the trial. In our judgment, this submission is untenable. It cannot 
reasonably be argued that a miscarriage of justice has been occasioned 
simply because the evidence might have emerged differently at the trial.
 In this regard, one should also bear in mind that at the re-sentencing 
hearing (whether before the High Court or, on appeal, before the Court 
of Appeal), the accused could have applied to the court for leave to 
adduce additional evidence which might have reduced his culpability for 
his offence. As we stated earlier, the burden of producing "sufficient 
material” and persuading the court, based on such material, that there 
has been a miscarriage of justice rests on the applicant who seeks a 
review of a concluded criminal appeal. The applicant cannot simply 
premise his application on the mere possibility that the outcome in his 
case could have been different.
118    In the context of the Present Application, what the Applicant has to show is that there is in fact a powerful probability that the outcome would have been different if he had known of the CA (Re-sentencing) test at the time of his trial. The Applicant, however, has only alluded to the mere possibility that the result in his case could
 have been different. As we have just emphasised, that in itself is not 
enough. The Applicant has not furnished details of what other evidence 
he would have led at his trial (or, for that matter, at the 
re-sentencing hearing if he had decided then to seek leave to adduce 
further evidence) had he known of the CA (Re-sentencing) test 
at the time, how else he would have conducted his defence or, most 
pertinently, how this would have affected this court’s decision in CA (Re-sentencing).
 An applicant who seeks to have a concluded criminal appeal reopened 
cannot approach the court with the expectation that the court will 
proceed on mere speculation and supposition, or that it will fill in 
gaps in his case. On that basis alone, we would reject the argument set 
out at [113(a)] above.
119    As far as we can see, the only basis the Applicant could have for saying that the outcome in CA (Re-sentencing) might have been different had he known, at the time of his trial, of the CA (Re-sentencing)
 test is that he might have led more evidence to persuade the trial 
judge that he had not struck the deceased three or more times. However, 
as we explained at [99]–[100] above, the opinion of the majority in CA (Re-sentencing) was that the number of blows inflicted on the deceased, although relevant, was not
 determinative as to whether a sentence of death should be imposed on 
the Applicant. Even if the majority had accepted the Applicant’s 
evidence that he had struck the deceased only twice, they would still 
have been satisfied that the death penalty was warranted because the 
blows which the Applicant inflicted on the deceased were: (a) directed 
towards a defenceless victim; (b) inflicted on a vulnerable region of 
the body; and (c) delivered with such force that it was clear that the 
Applicant displayed "a blatant disregard for human life” at the time of 
the attack. In our judgment, therefore, it cannot reasonably be argued 
that the Applicant has suffered a miscarriage of justice due to his lack
 of knowledge of the CA (Re-sentencing) test at the time of his
 trial. In any event, as we pointed out earlier, the Applicant had the 
opportunity to apply, both at the re-sentencing hearing and at the 
hearing of CA (Re-sentencing), for leave to adduce further evidence, but he did not avail himself of the opportunity at either hearing.
120    Mr Mohan
 has also argued that it follows from the above that the Applicant was 
treated unequally because future offenders who are charged with murder 
would have a better chance of escaping the death penalty than the 
Applicant (see [113(a)] above). Not only would such an offender be able 
to lead evidence at his trial which might put him in a better position 
to be considered for the alternative sentence of life imprisonment and 
caning, he might also "enter a plea of [guilty] on the basis that the 
[P]rosecution does not seek the death penalty”.[note: 37]
 This, Mr Mohan contends, is a violation of the Applicant’s right under 
Art 12 of the Constitution to the equal protection of the law.
121    In
 our judgment, this argument is untenable. At the time the Applicant 
committed the offence of murder, the death penalty was mandatory. That 
was the sentence which every offender (including the Applicant)
 could expect to receive for the offence. When Parliament passed the 
2012 Amendment Act, it took the exceptional step of affording persons 
who had been convicted of murder before the commencement date of that 
Act an opportunity to be re-sentenced. This is a departure from the 
usual rule that statutes apply with prospective effect. If Parliament 
had elected not to extend the opportunity of re-sentencing to 
offenders such as the Applicant, neither the Applicant nor any other 
similarly-situated offender could have had any constitutional basis for 
complaint as they would have been correctly sentenced according to the 
law as it stood at the time they committed their offences. Their only 
recourse, in the event of an unsuccessful appeal against their 
conviction for murder, would have been to petition the President for 
clemency.
122    Following the change in the law, the Applicant and other offenders in the same class – ie, persons who had been convicted of murder and sentenced to death while the death penalty was mandatory
 for that offence – had the same right to expect that they would be 
fairly and equally considered for the alternative sentence of life 
imprisonment and caning according to the procedure set out in the 2012 
Amendment Act. The Applicant has not asserted that he was given any less
 of a chance than other offenders in a similar position to argue for 
that alternative sentence in lieu of the sentence of death originally 
imposed by the trial judge. It is wrong for the Applicant to compare 
himself with future offenders who are charged with murder because the 
latter belong to an entirely different class of offenders. The fact that
 such future offenders might, as Mr Mohan has suggested, enter a guilty 
plea on the condition that the Prosecution does not seek the death 
penalty is not evidence of unequal treatment which violates the right of
 equal protection under Art 12(1) of the Constitution.
The decision in CA (Re-sentencing) breached the rule against double jeopardy
123    We turn now to Mr Mohan’s submission at [113(b)] above that the decision in CA (Re-sentencing)
 breached the rule against double jeopardy. This rule, which protects a 
person from the perils of facing multiple trials for the same offence, 
is embodied in s 244 of the CPC and Art 11(2) of the Constitution. The 
latter provides:
A person who has been convicted or acquitted of an offence shall not be tried again for the same offence except where the conviction or acquittal has been quashed and a retrial ordered by a court superior to that by which he was convicted or acquitted. [emphasis added]
124    Mr Mohan submits that the rule against double jeopardy is engaged in the instant case for the following reasons:[note: 38]
(a)     The re-sentencing hearing before the Re-sentencing Judge was comparable to a trial.
(b)     In
 re-sentencing the Applicant to life imprisonment, the Re-sentencing 
Judge could be said to have "acquitted” the Applicant of the death 
penalty.
(c)     Therefore,
 to allow the Prosecution to appeal against the Re-sentencing Judge’s 
decision and seek to re-impose the death penalty "would be to overturn 
the effective acquittal of the Applicant … in breach of the principle of
 double jeopardy”.[note: 39]
125    With
 respect, we find this argument untenable. When the Prosecution lodged 
its appeal against the sentence imposed by the Re-sentencing Judge, it 
was exercising its undoubted right of appeal. An appeal is not a second 
trial. The rule against double jeopardy is that a person cannot be made 
to face more than one trial for the same offence. It certainly does not bar an appeal
 from being brought against a first-instance decision made at the end of
 a trial. Moreover, the Prosecution’s appeal was only against sentence. 
In the circumstances, we do not see how the rule against double jeopardy
 could possibly have been engaged, let alone breached, here.
126    In this regard, the Applicant’s reliance on the decision of the Supreme Court of the United States in Arizona v Dennis Wayne Rumsey 467 US 203 (1984) ("Arizona”) is misplaced. American jurisprudence on the death penalty is complex, but a brief prĂ©cis will suffice. In Furman v Georgia
 408 US 238 (1972), it was held that the imposition of the death penalty
 without adequate procedural safeguards to ensure consistency in 
application was unconstitutional. Since then, all death penalty 
jurisdictions in the United States have introduced a two-phase system. 
During the first phase (viz, the "trial” phase), the jury determines whether the accused is guilty of a capital offence; and during the second phase (viz,
 the "penalty” phase), the same jury (or, in some States, the trial 
judge) ascertains whether any statutory aggravating factors regulating 
the imposition of the death penalty exist (see, generally, Cantero and Kline at pp 5–6 and 12–17).
127    In Arizona,
 the appellant was convicted of first-degree murder at the "trial” 
phase, and the question during the "penalty” phase was whether he had 
killed "as consideration for the receipt, or in expectation of the 
receipt, of anything of pecuniary value” (at 205), that being an 
aggravating factor which would have warranted sentencing him to death. 
The trial court answered this question in the negative on the basis that
 the statutory provision concerned applied only to contract killings. 
Its interpretation was overturned on appeal by the Supreme Court of 
Arizona, which held that the provision could also encompass situations 
where theft was committed in the course of a murder, and remitted the 
matter for the appellant to be re-sentenced. The trial court then found 
that the requisite statutory aggravating factor was present and 
sentenced the appellant to death. On appeal to the Supreme Court of 
Arizona, the appellant argued that a retrial of the "penalty” phase of 
the proceedings violated the rule against double jeopardy because that 
phase formally resembled a trial, in that the Prosecution was required 
to prove certain statutorily-defined facts beyond a reasonable doubt in 
order to support a sentence of death. This argument was accepted and the
 appellant’s sentence of death was replaced with a sentence of life 
imprisonment by the Arizona Supreme Court, whose decision was later 
affirmed by the Supreme Court of the United States.
128    Thus
 presented, it can be seen that the position in the United States is 
very different from our own. First, in Singapore, no single fact is a 
condition precedent to the imposition of the death penalty (see [90] 
above). Second, it is incorrect to compare the re-sentencing process 
under the 2012 Amendment Act to a trial, or to say that the decision in a
 re-sentencing application to impose a sentence of life imprisonment and
 caning instead of a sentence of death constitutes an "acquittal” in 
relation to the latter sentence. As this court explained in Public Prosecutor v Aniza bte Essa [2009] 3 SLR(R) 327 at [60]–[62], the sentencing process is not a "second trial”. In the premises, we see no basis for Mr Mohan’s argument that the rule against double jeopardy was violated vis-Ă -vis the Applicant in CA (Re-sentencing).
129    We
 also reject the notion that the Applicant had any "legitimate 
expectation” that he would not be sentenced to death after the 
Re-sentencing Judge’s decision in HC (Re-sentencing). As the 
Public Prosecutor rightly pointed out, the Applicant failed to point to 
any representation made by the Prosecution that it would not appeal 
against a sentence of life imprisonment and caning imposed by the 
re-sentencing court.[note: 40]
 The Applicant had a right to a re-sentencing decision at first 
instance, subject to an appeal to this court. That right was accorded to
 him. Until the legal process had drawn to a close, there could not have
 been any basis for the Applicant to assert any "expectation”, let alone
 a "legitimate” one, that he would only face a sentence of life 
imprisonment and caning instead of a sentence of death. For these 
reasons, the Applicant’s argument as set out at [113(b)] above is 
utterly without foundation.
Conclusion
130    For
 the foregoing reasons, we dismiss the Present Application and hold that
 the sentence of death imposed on the Applicant on 14 January 2015 shall
 stand. We direct that the stay of execution of the sentence which we 
granted on 5 November 2015 be lifted. The sentence will be carried into 
effect on such date as the President, acting in accordance with the 
Constitution, shall direct.
Coda: some observations on procedure and practice in applications for review
131    We
 would like to conclude this judgment with some remarks on procedure and
 practice in relation to applications to reopen concluded criminal 
appeals. In Hong Kong (see Habib Ahmed v Hong Kong Special Administrative Region
 [2010] HKCU 1761) as well as the United Kingdom, applications to reopen
 a final appellate court’s decision cannot be brought without leave. 
Applications for leave are first heard on paper and disposed of without 
the other party necessarily being called on to respond.
132    In
 this regard, where the United Kingdom is concerned, r 52.17 of the 
English CPR (which, as mentioned at [28] above, was introduced post-Taylor) sets out the procedure which must be adhered to when an application to review a concluded civil appeal is brought. The relevant rules (see rr 52.17(4)–52.17(7)) provide as follows:
(4)    Permission
 is needed to make an application under this rule to reopen a final 
determination of an appeal even in cases where under rule 52.3(1) 
permission was not needed for the original appeal.
(5)    There is no right to an oral hearing of an application for permission unless, exceptionally, the judge so directs.
(6)    The
 judge will not grant permission without directing the application to be
 served on the other party to the original appeal and giving him an 
opportunity to make representations.
(7)    There is no right of appeal or review from the decision of the judge on the application for permission, which is final.
Section VII
 of Practice Direction 52A of the English CPR lays down more detailed 
guidance on the form to be used and the time frame for making such 
applications:
7.1    A party applying for 
permission to reopen an appeal or an application for permission to 
appeal must apply for such permission from the court whose decision the 
party wishes to reopen.
7.2    The 
application for permission must be made by application notice and be 
supported by written evidence, verified by a statement of truth. A copy 
of the application for permission must not be served on any other party 
to the original appeal unless the court so directs.
7.3    Where
 the court directs that the application for permission is to be served 
on another party, that party may, within 14 days of the service on him 
of the copy of the application, file and serve a written statement 
either supporting or opposing the application.
7.4    The application for permission will be considered on paper by a single judge.
133    In
 our view, the introduction of a leave stage for applications to reopen 
concluded criminal appeals would better balance the rights and interests
 of all persons who make use of scarce judicial resources. Unmeritorious
 applications for review could be weeded out at an early stage, with 
only those which disclose a legitimate basis for the exercise of this 
court’s power of review being allowed to proceed. In this connection, we
 note that s 384 of the CPC already permits the summary rejection of 
appeals without the matter being set down for oral hearing provided the 
court is unanimously satisfied that the grounds of appeal do not 
disclose any sufficient ground of complaint (see Mohd Fauzi bin Mohamed Mydin v Public Prosecutor [2015] SGHC 313
 at [22]–[31]). There is, however, currently no equivalent provision in 
the CPC for post-appeal applications to reopen concluded criminal cases.
134    We
 think there is merit in the enactment of statutory provisions to govern
 post-appeal applications for review to introduce, among other things, 
the requirement that the leave of this court must be obtained before 
bringing applications of this nature. Should a leave stage be 
introduced, provision could also be made for the rejection of such 
applications without the necessity of an oral hearing or without the 
need for the named respondent being called on to respond. We commend 
these suggestions for Parliament’s consideration.
