Summary
In Nagaenthran a/l K Dharmalingam v Attorney-General and another matter ([2022] SGCA 26), the Court of Appeal dismissed both (i) the appellant’s civil appeal against the High Court’s refusal of leave to commence judicial review proceedings to prevent his impending execution, and (ii) his criminal motion seeking an independent psychiatric assessment and a stay of execution pending that assessment. The appellant’s central contention was that, due to an alleged deterioration in his mental faculties since his offence nearly 13 years earlier, the sentence of death should not be carried out.
The Court of Appeal held that the proceedings were an egregious abuse of process, aimed at unjustifiably delaying the carrying into effect of a final sentence. It emphasised the principle of finality in criminal justice: while not as rigid as in civil matters, there must be a point at which litigation ends and the “last word” of the court remains the last word. The court further found that the appellant’s case was baseless in fact and law, including the manner in which evidence was presented and deployed.
What Were the Facts of This Case?
The appellant, Mr Nagaenthran a/l K Dharmalingam, was charged under s 7 of the Misuse of Drugs Act (Cap 185, 2008 Rev Ed) (“MDA”) with importing not less than 42.72g of diamorphine into Singapore on 22 April 2009. After trial, he was convicted and sentenced to the mandatory death penalty. His conviction and sentence were upheld by the Court of Appeal in Public Prosecutor v Nagaenthran a/l K Dharmalingam [2011] 2 SLR 830 and Nagaenthran a/l K Dharmalingan v Public Prosecutor [2011] 4 SLR 1156 (referred to in the judgment as “Nagaenthran (Appeal)”).
After the Court of Appeal’s decision in Nagaenthran (Appeal), the MDA was amended to introduce s 33B, which created a mechanism for certain convicted drug traffickers/importers to be sentenced to life imprisonment instead of death, notwithstanding that the offence would otherwise attract the mandatory death penalty. In 2015, the appellant sought to benefit from this new provision. He filed Criminal Motion No 16 of 2015 (“CM 16”) seeking re-sentencing to life imprisonment under s 33B(1)(b) read with s 33B(3). He also filed Originating Summons No 272 of 2015 (“OS 272”) seeking leave to commence judicial review against the Public Prosecutor’s decision not to issue a certificate of substantive assistance under s 33B(2)(b).
Both CM 16 and OS 272 were dismissed by the High Court. The High Court found, among other things, that the appellant was not suffering from an abnormality of mind within the meaning of s 33B(3)(b). The appellant’s appeals against those dismissals were also rejected by the Court of Appeal in Nagaenthran a/l K Dharmalingam v Public Prosecutor and another appeal [2019] 2 SLR 216 (“Nagaenthran (CA)”). Pertinently, the Court of Appeal held that the appellant could not avail himself of s 33B(3). Even assuming he suffered from an abnormality of mind, it did not substantially impair his mental responsibility such that s 33B(3) could be invoked.
After the conclusion of these proceedings, the appellant petitioned the President for clemency, but that application was rejected. His execution was eventually scheduled for 10 November 2021, and he was notified of this on 27 October 2021. It was against this backdrop of finality—after multiple rounds of litigation and unsuccessful clemency—that the appellant brought the present applications in late 2021.
What Were the Key Legal Issues?
The first issue in CA 61 was whether the High Court was correct to dismiss OS 1109, which sought leave to commence judicial review proceedings to challenge the impending execution. Although OS 1109 was framed as a leave application, the appellant’s practical objective was to obtain further time and medical evidence to support the argument that his death sentence should not be carried out.
The second issue in CM 30 was whether the appellant should be assessed by an independent panel of psychiatrists and whether execution should be stayed pending that assessment. The appellant’s argument was that his mental faculties had deteriorated since the time of the offence, and that this present-day deterioration should prevent the execution of the death sentence.
Underlying both issues was a broader procedural and constitutional concern: whether the appellant’s applications—coming after extensive prior litigation—could properly be brought at that stage, particularly where the evidence relied upon appeared to have been withheld or deployed in a manner inconsistent with candour and procedural fairness. The Court of Appeal also had to consider the extent to which the principle of finality constrains repeated applications, especially where the court perceives an attempt to delay execution without merit.
How Did the Court Analyse the Issues?
The Court of Appeal began by situating the dispute within the criminal justice system’s need for finality. It referenced its earlier observations in Public Prosecutor v Pang Chie Wei and other matters [2021] SGCA 101, where the court explained that finality is an important function of justice. While finality is not applied as unyieldingly in criminal matters as in civil matters, the court stressed that litigation cannot be prolonged indefinitely. The court invoked Kho Jabing v Public Prosecutor [2016] 3 SLR 135 and Kho Jabing v Attorney-General [2016] 3 SLR 1273 to emphasise that no applicant should be allowed to prolong matters ad infinitum through multiple applications.
Against that principle, the court assessed the appellant’s conduct and the procedural history. It described the proceedings as a “blatant and egregious abuse of the court’s processes”, conducted with what appeared to be the aim of unjustifiably delaying the execution. The court’s analysis was not limited to whether the appellant’s legal argument could be framed in the abstract; it also examined whether the applications were supported by credible, properly presented evidence and whether they were brought in good faith.
On the evidence and timing, the court traced how OS 1109 and CM 30 were filed and supported. OS 1109 was filed on 2 November 2021 through then counsel, Mr Ravi. The sole factual basis was an affidavit in which Mr Ravi deposed to a “firm belief” as to the appellant’s “mental age”. However, Mr Ravi acknowledged he lacked the medical expertise to form such a view. This undermined the reliability of the factual foundation for seeking judicial review leave.
More significantly, during the hearing of OS 1109 on 8 November 2021, Mr Ravi informed the High Court judge that he had an affidavit from the appellant’s brother, Mr Navinkumar, stating that the appellant’s mental condition had deteriorated significantly. When asked whether that affidavit was before the court, Mr Ravi said it had been filed as an exhibit to an affidavit supporting CM 30, which had been filed directly to the Court of Appeal during the hearing. The Court of Appeal found it unclear why CM 30 needed to be separately filed when the evidence could and should have been placed before the High Court in OS 1109, especially given that the hearing of OS 1109 was on 8 November 2021.
The court further noted that CM 30’s evidence first appeared in an unaffirmed form annexed to an affidavit affirmed by Mr Ravi on 8 November 2021, with an explanation that Mr Navinkumar could not affirm the affidavit in time due to urgency. Yet, the affirmed affidavit was later filed on the same day and had in fact been affirmed three days earlier, on 5 November 2021. The court also observed that the contents indicated the affidavit was prepared in support of OS 1109 rather than CM 30. The appellant’s subsequent counsel, Ms Netto, confirmed that Mr Ravi had received the affirmed affidavit on 5 November 2021. This led the Court of Appeal to conclude that there was no need for CM 30 to be separately filed and that all papers could and should have been filed for OS 1109.
From these facts, the Court of Appeal inferred that the evidence may have been deliberately withheld to “deploy” it in support of a further application after OS 1109 was dismissed. The court also suggested that Mr Ravi may have misrepresented the position in his affidavit dated 8 November 2021 regarding why the affidavit could not be affirmed in time. The court’s reasoning here reflects a broader judicial concern: counsel and litigants must not treat procedural steps as tactical tools to circumvent adverse rulings, particularly where the evidence is already available.
Although the excerpt provided is truncated, the Court of Appeal’s overall approach is clear: it treated the appellant’s attempt to re-litigate the death sentence on the basis of present mental deterioration as legally and factually unsupported, and it viewed the procedural strategy as an abuse of process. The court’s repeated emphasis on finality and the court’s disapproval of “drip-feeding” applications and evidence underscores that even where constitutional or criminal justice arguments are raised, courts will scrutinise whether the applications are meritorious and properly grounded.
What Was the Outcome?
The Court of Appeal dismissed both CA 61 and CM 30. The dismissal of CA 61 meant that the High Court’s refusal of leave to commence judicial review proceedings to prevent the execution stood. The dismissal of CM 30 meant that the appellant was not granted an independent psychiatric assessment through the mechanism sought, and no stay of execution was ordered pending such assessment.
Practically, the effect was that the appellant’s execution schedule was not halted by the new applications. More broadly, the decision signals that late-stage attempts to delay execution through repeated applications—especially where evidence is mishandled or appears to be deployed tactically—will be met with strong judicial resistance.
Why Does This Case Matter?
This case matters because it illustrates the Court of Appeal’s firm stance on finality in criminal proceedings and its willingness to characterise repeated, meritless applications as abuse of process. While Singapore’s criminal justice system recognises that constitutional and procedural safeguards may require judicial scrutiny, Nagaenthran demonstrates that such scrutiny is not open-ended. Once the courts have delivered the “last word”, litigants cannot use successive applications to keep the matter in a perpetual state of uncertainty.
For practitioners, the decision is also a cautionary tale about evidential discipline and counsel’s duties to the court. The Court of Appeal’s findings regarding the timing, availability, and deployment of the brother’s affidavit show that courts will examine not only what evidence is presented, but also how and when it is presented. Where evidence is withheld, misrepresented, or used as a tactical instrument to obtain procedural advantages, the court may respond with dismissal and strong censure.
Finally, the case is significant for how it frames arguments about mental faculties in the context of death penalty execution. The appellant’s argument was premised on deterioration since the offence, rather than on mental responsibility at the time of the offence. The Court of Appeal’s rejection of the applications indicates that such arguments must still satisfy strict legal and factual thresholds, and cannot be used as a vehicle to revisit issues already determined in earlier proceedings.
