Summary
In Iskandar bin Rahmat v Public Prosecutor ([2021] SGCA 89), the Court of Appeal dismissed an application by a convicted murderer for leave to intervene in an unrelated pending criminal appeal. The applicant, who had already exhausted his own criminal appeal and was serving a sentence of the mandatory death penalty, sought to support a constitutional challenge to ss 299 and 300(a) of the Penal Code being advanced by another appellant in a separate case. The applicant’s intended purpose was to use any favourable constitutional ruling to later mount a review application under s 394H of the Criminal Procedure Code (“CPC”).
The Court held that it had no jurisdiction to grant leave to intervene in an unrelated criminal appeal merely because the applicant had an interest in the point of law being considered. The Court emphasised the principle of finality in criminal litigation and rejected the notion that an accused person can bypass the strict statutory conditions governing review of concluded criminal appeals by seeking intervention in another pending matter. The Court further found that s 6 of the CPC (which allows the court to adopt procedure where no special provision exists) could not be used to create a jurisdictional basis inconsistent with the CPC and the statutory limits on the Court of Appeal’s criminal jurisdiction.
What Were the Facts of This Case?
The applicant, Iskandar bin Rahmat, was convicted by the High Court of two counts of murder under s 300(a) of the Penal Code (Cap 224, 2008 Rev Ed) and sentenced to the mandatory death penalty. On appeal, he challenged his convictions on the basis that his actions did not demonstrate an intention to cause death, but rather reflected an intention to cause injuries sufficient in the ordinary course of nature to cause death under s 300(c) of the Penal Code. He also relied on exceptions under s 300, including private defence, sudden fight, and diminished responsibility.
His appeal was dismissed by the Court of Appeal on 3 February 2017 in Iskandar bin Rahmat v Public Prosecutor and other matters [2017] 1 SLR 505 (“the 2017 Judgment”). As a consequence, the legal process available to him in relation to his conviction and sentence was effectively at an end, subject only to extremely limited avenues for review.
More than a year after the 2017 Judgment, on 14 February 2018, the applicant wrote to the Law Society to complain about his trial counsel, alleging failure to comply with his instructions in conducting his defence. A four-member Inquiry Committee recommended that no formal investigation by a Disciplinary Tribunal was necessary and that the complaint be dismissed. The Council of the Law Society informed him on 20 March 2019 that it would not take further action. The applicant then filed an originating summons in the High Court (HC/OS 716/2019) under s 96 of the Legal Professions Act seeking review of the Council’s determination and an order directing the Law Society to apply for the appointment of a Disciplinary Tribunal. The High Court dismissed OS 716 on 10 October 2019, and the applicant’s appeal against that decision was also dismissed by the Court of Appeal on 5 July 2021.
While the disciplinary-related proceedings were ongoing, the applicant filed the present application on 11 June 2021 seeking leave to intervene in CA/CCA 36/2020 (“CCA 36”). CCA 36 was an unrelated pending criminal appeal in which another appellant, Teo Ghim Heng (“Teo”), was raising a constitutional challenge to ss 299 and 300(a) of the Penal Code. The applicant’s intervention was intended to enable him to add an argument supporting Teo’s constitutional challenge, and, if successful, to use the outcome to support a future review application under s 394H of the CPC.
What Were the Key Legal Issues?
The sole issue before the Court of Appeal was jurisdictional: whether the Court had the jurisdiction to grant leave to the applicant to intervene in CCA 36. This issue required the Court to consider the scope of its criminal jurisdiction and whether any statutory provision could support intervention by a person who was not a party to the pending criminal appeal.
In addressing jurisdiction, the Court also had to confront the applicant’s attempt to rely on procedural flexibility under s 6 of the CPC. The applicant argued that where no special provision exists, the Court may adopt procedure “as the justice of the case may require” so long as it is not inconsistent with the CPC or other law. He further suggested that the Court could model intervention procedures on the civil intervention rules in the Rules of Court (O 15 r 6(2)(b)(ii) and 6(3)).
Underlying the jurisdictional question was a broader concern about the finality of criminal litigation. The applicant acknowledged that he could not presently seek a review under s 394H because his constitutional arguments would not satisfy the statutory threshold that the earlier decision was “demonstrably wrong.” He also acknowledged that he could not mount a constitutional challenge through civil processes as that would amount to an abuse of process. The Court therefore had to decide whether intervention in another pending appeal could be used to circumvent those constraints.
How Did the Court Analyse the Issues?
The Court began by restating the basic concept of jurisdiction as the authority “to hear and determine a dispute that is brought before it.” It then identified the statutory basis for its criminal jurisdiction. The Court of Appeal’s criminal jurisdiction is conferred by s 60D of the Supreme Court of Judicature Act (Cap 322). That provision lists the matters constituting the Court’s criminal jurisdiction, including appeals from the General Division’s original criminal jurisdiction, petitions for confirmation, reviews, and other specified categories under the CPC.
Against that statutory framework, the Court asked whether the applicant’s application for leave to intervene in CCA 36 fell within any of the categories of matters over which the Court of Appeal could exercise criminal jurisdiction. The Court’s answer was no. The applicant was not involved in any proceedings over which the Court could exercise criminal jurisdiction at the time of the application. His own criminal appeal had already been dismissed, and there was no pending criminal proceeding involving him that would bring his application within the Court’s statutory criminal jurisdiction.
The Court rejected the applicant’s argument that his interest in the point of law being canvassed in CCA 36 could itself justify intervention. The Court held that litigants, including accused persons, do not have a right to intervene in an unrelated pending proceeding simply because they share a common interest in a point of law. The Court reasoned that if such a right existed, it would open the floodgates to intervention in almost any case where a legal issue might later affect other litigants. The Court acknowledged that the common law naturally allows legal principles to develop across cases, but that does not translate into a licence for intervention in unrelated proceedings.
In considering the applicant’s reliance on s 6 of the CPC, the Court treated the provision as procedural in nature and not a mechanism to create jurisdiction where none exists. Section 6 allows the court to adopt procedure where no special provision has been made, but it does not permit the court to adopt a procedure that is inconsistent with the CPC or other law. The Court accepted the prosecution’s position that the applicant’s intended intervention would be inconsistent with the CPC’s structure and with the statutory limits on the Court of Appeal’s criminal jurisdiction. In other words, s 6 could not be used to convert a non-jurisdictional application into a jurisdictionally valid one.
The Court also addressed the applicant’s reliance on civil intervention rules under the Rules of Court. While the applicant argued that the Court could adapt O 15 r 6(2)(b)(ii) and 6(3) for the criminal context, the Court’s reasoning indicates that adaptation cannot overcome the threshold requirement of jurisdiction. Even if the civil rules might provide a conceptual model for intervention, the criminal appellate context is governed by the CPC and the statutory conferral of criminal jurisdiction. Where the Court’s criminal jurisdiction is limited to specific categories, civil procedural analogies cannot supply the missing jurisdictional foundation.
Finally, the Court’s analysis was informed by the principle of finality. The applicant’s strategy—intervening in another appeal to obtain a constitutional ruling that could later support a review—was precisely the kind of collateral approach the finality principle seeks to prevent. The Court observed that the applicant’s attempt would effectively allow an accused person who has exhausted his legal options to bypass the strict conditions governing review applications under s 394H of the CPC. The Court therefore treated the applicant’s proposed intervention as an impermissible route to a collateral attack on the correctness of his conviction.
What Was the Outcome?
The Court of Appeal dismissed the applicant’s application for leave to intervene in CCA 36. The Court held that it had no jurisdiction to permit intervention by an accused person in an unrelated pending criminal appeal solely because of an interest in a point of law being considered in that appeal.
Practically, the decision means that convicted persons who have exhausted their own criminal appeals cannot seek to “piggyback” on other pending appeals to advance constitutional arguments, at least not through intervention in the Court of Appeal. Their ability to obtain relief remains tied to the limited statutory avenues for review and other procedures that meet the relevant thresholds.
Why Does This Case Matter?
This decision is significant for criminal practitioners because it draws a clear jurisdictional boundary around intervention in appellate criminal proceedings. It confirms that the Court of Appeal’s criminal jurisdiction is not open-ended and cannot be expanded by procedural analogies or by invoking general procedural provisions such as s 6 of the CPC. For lawyers, the case underscores the importance of identifying the statutory source of jurisdiction before considering procedural mechanisms.
The case also reinforces the principle of finality in criminal litigation. The Court was concerned that allowing intervention based on shared legal issues would undermine the carefully calibrated statutory scheme for review of concluded criminal appeals. In particular, it prevents a situation where an accused person could avoid the “demonstrably wrong” requirement in s 394H by seeking to obtain a favourable constitutional ruling in another case and then using it as a basis for review.
From a constitutional litigation perspective, the case illustrates that constitutional arguments in criminal matters must be pursued through routes consistent with the criminal appellate and review framework. While constitutional challenges may be raised in appropriate cases, the Court will not permit procedural workarounds that effectively circumvent the statutory constraints applicable to concluded convictions. Practitioners should therefore plan constitutional strategies with attention to timing, standing, and jurisdictional fit, rather than relying on intervention as a general remedy.
