Summary
In Iskandar bin Rahmat v Public Prosecutor ([2021] SGCA 89), the Court of Appeal dismissed the applicant’s criminal motion seeking leave to intervene in an unrelated pending criminal appeal, CA/CCA 36/2020 (“CCA 36”). The applicant, who had already been convicted of murder and whose own appeal had been dismissed, wanted to support a constitutional challenge to ss 299 and 300(a) of the Penal Code mounted by another appellant in CCA 36. If that constitutional challenge succeeded, the applicant intended to use the outcome to pursue a further review application under s 394H of the Criminal Procedure Code (“CPC”).
The Court held that it lacked jurisdiction to permit intervention in an unrelated criminal appeal merely because the applicant had an interest in the point of law being argued. The Court emphasised the principle of finality in criminal litigation and rejected the notion that an accused person can bypass the strict statutory framework for review by seeking to intervene in another case. The decision clarifies the limits of the Court of Appeal’s criminal jurisdiction and the proper use of procedural mechanisms such as s 6 CPC.
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 and sentenced to the mandatory death penalty. On appeal, his conviction was upheld: 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 Judgment”). In that earlier appeal, the applicant argued that his actions did not demonstrate an intention to cause death, but rather an intention to cause injuries sufficient in the ordinary course of nature to cause death under s 300(c). He also relied on exceptions under s 300, including private defence, sudden fight, and diminished responsibility.
After his conviction and appeal were finalised, the applicant pursued other avenues. More than a year after the Court of Appeal’s dismissal, on 14 February 2018, he wrote to the Law Society to complain about his trial counsel, alleging failure to comply with his instructions in the conduct of his defence. A four-member Inquiry Committee unanimously recommended that no formal investigation by a Disciplinary Tribunal was necessary, and the Council of the Law Society informed him on 20 March 2019 that no further action would be taken.
Dissatisfied, the applicant filed HC/OS 716/2019 under s 96 of the Legal Professions Act seeking a review of the Council’s determination and an order directing the Law Society to apply to the Chief Justice for the appointment of a Disciplinary Tribunal. The High Court dismissed OS 716 on 10 October 2019, and the applicant’s appeal against that dismissal (CA/CA 9/2020) was also dismissed by the Court of Appeal on 5 July 2021.
While the appeal in CA 9 was still ongoing, the applicant filed the present motion on 11 June 2021. The motion sought leave to intervene in CCA 36, an unrelated pending criminal appeal involving Teo Ghim Heng. The applicant’s ostensible purpose was to raise an additional argument supporting Teo’s constitutional challenge to ss 299 and 300(a) of the Penal Code. Specifically, the applicant intended to argue that the constitutional provisions violated Article 12(1) of the Constitution, Article 93, and/or the separation of powers. If Teo’s constitutional challenge succeeded, the applicant planned to use that development to mount a review application under s 394H CPC.
What Were the Key Legal Issues?
The sole issue before the Court of Appeal was jurisdictional: whether the Court had the authority to grant leave to the applicant to intervene in an unrelated pending criminal appeal (CCA 36). This required the Court to consider the scope of its criminal jurisdiction and whether any statutory or inherent power could support intervention in circumstances where the applicant was not a party to the pending appeal and had no ongoing criminal proceeding of his own before the Court.
Related to the jurisdictional question was the applicant’s attempt to rely on procedural flexibility. He argued that s 6 CPC empowers the Court to adopt procedure “as the justice of the case may require” for matters where no special provision exists, and that the Court could model intervention rules on the civil intervention framework in the Rules of Court. The Court therefore had to assess whether s 6 CPC could be used to create or expand intervention rights in the appellate criminal context, and whether such an approach would be inconsistent with the CPC and the statutory architecture governing criminal appeals and reviews.
How Did the Court Analyse the Issues?
The Court began by restating the foundational concept of jurisdiction. Jurisdiction is the authority, however derived, to hear and determine a dispute brought before the court. The Court emphasised that its criminal jurisdiction is not open-ended; it is conferred by statute. In particular, the Court of Appeal’s criminal jurisdiction is statutorily conferred by s 60D of the Supreme Court of Judicature Act (Cap 322). That provision enumerates the categories of matters that fall within the Court of Appeal’s criminal jurisdiction, including appeals from the General Division in original criminal jurisdiction, confirmation petitions, reviews, and other specified criminal references.
On that basis, the Court held that the applicant’s motion did not properly invoke the Court’s criminal jurisdiction. The applicant was not involved in any pending criminal proceeding before the Court. His own appeal against conviction had already been dismissed years earlier, and there was no ongoing criminal appeal or review in which he was a party. The Court therefore rejected the idea that an interest in the point of law being argued in another case could substitute for a jurisdictional basis. The Court’s reasoning was that jurisdiction cannot be manufactured by procedural ingenuity; it must be anchored in the statutory categories that define what the Court may hear.
Crucially, the Court also addressed the policy and systemic implications of allowing intervention on that basis. It observed 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 being considered. If such intervention were permitted, it would “open the floodgates” to litigation, because legal questions canvassed in one case may potentially affect many other cases. The Court characterised this as a predictable feature of common law adjudication, but one that is not a licence to intervene outside the proper procedural and jurisdictional channels.
In response to the applicant’s reliance on s 6 CPC and analogies to civil intervention rules, the Court considered whether those provisions could overcome the absence of jurisdiction. The Court’s approach was that s 6 CPC cannot be used to create a procedural pathway that is inconsistent with the CPC’s structure and the statutory limits on criminal jurisdiction. The Court also noted that the applicant’s proposed intervention would effectively allow him to bypass the strict conditions governing review applications under s 394H CPC. The applicant himself had acknowledged that he could not presently satisfy the requirement that the earlier Court of Appeal Judgment was “demonstrably wrong” for purposes of a review. Allowing him to intervene in CCA 36 to later leverage the outcome would undermine the finality principle and the legislative design of review as an exceptional remedy.
The Court further rejected the applicant’s reliance on Amarjeet Singh v Public Prosecutor [2021] 4 SLR 841. While the applicant argued that a criminal motion seeking leave to intervene could be ancillary to a primary criminal action, the Court’s analysis turned on the jurisdictional reality that the applicant was not a party to the primary criminal action and had no pending criminal proceeding of his own. The Court’s reasoning therefore distinguished between procedural mechanisms that operate within an existing jurisdictional framework and attempts to extend jurisdiction by analogy to civil procedure.
What Was the Outcome?
The Court of Appeal dismissed the applicant’s criminal motion (CA/CM 21/2021) seeking leave to intervene in CCA 36. The practical effect of the decision was that the applicant could not participate in Teo’s constitutional appeal by way of intervention, and could not use the intervention route to advance his intended constitutional arguments in that forum.
More broadly, the decision reinforced that the applicant’s ability to seek further relief remained governed by the existing statutory review framework, including the stringent threshold under s 394H CPC. The Court’s dismissal therefore preserved the finality of the applicant’s own conviction and prevented collateral re-litigation through procedural detours.
Why Does This Case Matter?
This case is significant for criminal procedure in Singapore because it draws a clear boundary around the Court of Appeal’s criminal jurisdiction and the permissible scope of intervention. Practitioners often confront the tension between (i) the desire to ensure that constitutional arguments are fully ventilated and (ii) the need to maintain procedural order and finality. The Court’s decision makes clear that shared legal issues do not, by themselves, justify intervention in unrelated criminal proceedings.
From a precedent and doctrinal perspective, Iskandar bin Rahmat underscores that jurisdiction is statutory and cannot be expanded through reliance on general procedural provisions such as s 6 CPC. While s 6 CPC provides flexibility for procedural gaps, it does not authorise the Court to create new jurisdictional pathways that would conflict with the CPC’s structure and the Supreme Court of Judicature Act’s allocation of criminal jurisdiction. This is a useful reminder for lawyers considering whether to invoke “justice of the case” language to justify procedural innovation in criminal appeals.
For accused persons and counsel, the decision also has practical implications for strategy. Where a conviction has become final, the route to further constitutional or legal challenges is constrained by the statutory review regime. The Court’s reasoning indicates that attempts to “stage” constitutional arguments through intervention in another pending appeal—especially where the applicant’s own review threshold is not presently met—will likely be rejected. Accordingly, lawyers should carefully evaluate whether their clients have an existing jurisdictional foothold before seeking intervention, and should not assume that the Court will treat interest in a point of law as sufficient.
