Summary
In Dzulkarnain bin Khamis v Public Prosecutor ([2023] SGCA 14), the Court of Appeal dismissed two criminal appeals and also refused a criminal motion seeking to adduce fresh evidence. The appeals arose from the conviction of two men, Dzulkarnain and Sanjay Krishnan, for capital drug offences under the Misuse of Drugs Act (MDA) involving cannabis. Dzulkarnain was convicted on a charge of delivering not less than 2375.1g of cannabis, while Sanjay was convicted on a charge of having the drugs in possession for the purpose of trafficking.
The Court of Appeal upheld the High Court’s findings on the evidential basis for identifying the relevant drug box and for establishing the chain of custody and the accused persons’ knowledge. It also confirmed that procedural and evidential objections raised by Sanjay did not undermine the trial judge’s conclusions. Finally, the Court of Appeal declined to remit the matter for further evidence, holding that the proposed fresh evidence did not meet the threshold for admission and would not materially affect the outcome.
What Were the Facts of This Case?
The events leading to the arrests occurred on 23 February 2015. Dzulkarnain drove a van to a bus stop near Tuas Checkpoint, where he collected a brown box (the “Brown Box”). Later that day, he drove the van to Lorong 21 Geylang and then to Lorong 37. CNB officers tailed the van, although one team lost sight of it temporarily; another team continued surveillance as the van reached Lorong 37.
At Lorong 37, CNB officers observed Dzulkarnain place the Brown Box behind a green dustbin marked with the number “14” (the “Green Bin”). The Green Bin was located next to No 14, Lorong 37 Geylang, Singapore, which became the “drop-off point”. After Dzulkarnain drove off, Sanjay arrived at Lorong 37 about five minutes later. Sanjay stopped beside the Green Bin, alighted, retrieved a brown box from behind the Green Bin, and then returned to his car and left.
Sanjay was apprehended by CNB officers around 4.35pm near Lorong 36 Geylang. About five minutes later, Dzulkarnain was arrested at an Esso petrol kiosk. Following Sanjay’s arrest, officers conducted a body search and searched his car at a multi-storey carpark at Block 56A Cassia Crescent (“MSCP”). Among the exhibits recovered were the brown box (later opened and analysed), multiple handphones, notebooks containing handwritten entries relating to drug transactions and prices, and weapons (two samurai swords and a knife). The Health Sciences Authority (HSA) analysis confirmed that the drug exhibits contained not less than 2375.1g of cannabis.
Before opening the box, Sanjay was asked about its contents. He purportedly shrugged and did not verbalise an answer. Officers recorded this reaction in a CNB operation field book. SI Tay then tore away masking tape sealing the box and removed five bundles of vegetable matter. Each bundle was packed and sealed into separate polymer bags, and the drug exhibits were placed into a green duffel bag (the “duffel bag”). From about 7.45pm to 8.30pm, SI Tay recorded a contemporaneous statement from Sanjay under s 22 of the CPC. In that statement, Sanjay said he did not know what the box contained.
Subsequently, Sanjay gave multiple further statements during investigations. In a cautioned statement recorded on 24 February 2015, he said he believed the box contained “illegal cigarettes” based on what he had been told by a person he referred to as “Malaysia Boy”. Although he did not sign that cautioned statement, the trial judge accepted it as an accurate record of what he told the investigating officer. In a later long statement recorded on 8 March 2015, Sanjay changed his account: he said he had been told by “Boy Lai” to take delivery of collectors’ hunting knives and that there “may also be contraband … cigarettes”. This shift in narrative became a focal point for the defence at trial and on appeal.
After Dzulkarnain’s arrest, CNB officers searched him and his van and seized a handphone later marked “DBK-HP1”. At about 5.15pm, Dzulkarnain was served with the Mandatory Death Penalty Notice and provided a statement in response (the “MDP Statement”). He stated that he did not know what the Brown Box contained, believed it likely contained cigarettes, and said he was paid $250 to collect and deliver the Brown Box. Officers also recorded a contemporaneous statement under s 22 of the CPC in which he maintained that he did not know the contents of the Brown Box.
What Were the Key Legal Issues?
The Court of Appeal had to address several legal issues, primarily concerning (1) whether the prosecution proved the identity of the drug exhibits beyond reasonable doubt, (2) whether the trial judge relied on admissible evidence in making findings, (3) whether the prosecution’s case theory was sufficiently coherent to avoid prejudicing the defence, and (4) whether Sanjay had rebutted the statutory presumption relating to knowledge under s 18(2) of the MDA.
For Dzulkarnain, the core issue was evidential: he argued that the trial judge erred in finding that the box containing the drugs that Sanjay collected was the same box that Dzulkarnain had left at the drop-off point. This required the appellate court to assess whether the trial judge’s inference on identity and continuity of the drug box was properly supported by the evidence.
For Sanjay, the appeal raised three main grounds. First, he contended that the trial judge erroneously relied on statements that were not admissible when making findings. Second, he argued that the prosecution’s case did not present a unified case theory but instead consisted of inconsistent and incompatible parts, which prejudiced his defence. Third, he maintained that the trial judge erred in concluding that he failed to rebut the s 18(2) presumption, and therefore that he knew the nature of the drugs.
How Did the Court Analyse the Issues?
The Court of Appeal began by situating the case within the statutory and procedural context of capital drug prosecutions. The MDA creates strict evidential consequences for accused persons in certain circumstances, including presumptions about knowledge. In such cases, the prosecution must still prove the essential elements of the offence beyond reasonable doubt, but the statutory framework can shift the evidential burden to the accused to rebut presumptions. The Court therefore examined whether the trial judge’s findings on identity, admissibility, and knowledge were legally sound and supported by the record.
On Dzulkarnain’s identity argument, the Court of Appeal focused on whether the evidence established that the Brown Box placed behind the Green Bin was the same box retrieved by Sanjay and later found to contain the cannabis. The trial judge had accepted the prosecution’s narrative that the drop-off point and the timing of events linked Dzulkarnain’s act to Sanjay’s retrieval. The appellate court upheld that approach, finding no error in the trial judge’s reasoning. In particular, the Court accepted that the surveillance observations, the location of the Green Bin, and the sequence of movements provided a sufficient evidential foundation for the inference that the drug box was the same one.
On Sanjay’s admissibility and procedural grounds, the Court of Appeal addressed the contention that the trial judge relied on statements that were not admissible. The Court analysed the trial judge’s use of the statements and the manner in which they were employed in arriving at factual findings. The Court’s approach reflected a common appellate principle: even where there are evidential objections, the appellate court must determine whether the trial judge actually relied on inadmissible material in a way that could have affected the outcome. Having reviewed the record, the Court of Appeal concluded that the trial judge’s findings were not undermined by any admissibility error of the kind alleged.
The Court also considered Sanjay’s complaint that the prosecution’s case theory was not unified and that it consisted of inconsistent and incompatible parts, thereby prejudicing the defence. The Court of Appeal treated this as a question of whether the prosecution’s evidence and theory, taken as a whole, remained coherent enough to allow the defence to understand the case it had to meet. The Court found that the prosecution’s case, though involving multiple statements and evolving accounts by Sanjay, remained anchored in the core factual narrative: Dzulkarnain’s delivery act at the drop-off point and Sanjay’s retrieval and possession of the drug exhibits. The existence of inconsistencies in Sanjay’s own statements did not necessarily mean the prosecution’s case was incoherent; rather, it could be understood as reflecting changes in Sanjay’s explanations.
The most substantial issue for Sanjay was the s 18(2) presumption. Under the MDA framework, where an accused is found in possession of controlled drugs, the law can presume knowledge of the nature of the drugs unless rebutted. The Court of Appeal examined whether Sanjay had offered credible evidence to rebut the presumption. It considered the content and timing of Sanjay’s statements: his contemporaneous statement that he did not know what the box contained; his earlier cautioned statement that he believed it contained illegal cigarettes based on information from “Malaysia Boy”; and his later long statement that he had been told to take delivery of hunting knives and that there “may also” be contraband cigarettes. The Court treated the shifting accounts as undermining the reliability of Sanjay’s claimed lack of knowledge.
In upholding the trial judge, the Court of Appeal emphasised that rebutting the presumption requires more than assertions; it requires evidence capable of raising a reasonable doubt as to knowledge. The Court found that Sanjay’s explanations did not sufficiently displace the presumption. The trial judge’s conclusion that Sanjay failed to rebut s 18(2) was therefore affirmed. The Court’s reasoning also aligned with the broader principle that appellate courts generally defer to trial judges on matters of credibility and weight, especially where the trial judge had the advantage of observing witnesses and assessing the overall evidential picture.
Finally, the Court addressed Sanjay’s criminal motion (CM 23) seeking leave to adduce fresh evidence. The proposed evidence was Sanjay’s own account of the location of a duffel bag containing the drug exhibits that had been seized from him. Sanjay argued that this would contradict a CNB officer’s testimony about custody and thereby affect the chain of custody. The Court of Appeal dismissed the application. It held that the fresh evidence did not meet the threshold for admission and would not materially affect the outcome. In particular, the Court considered whether the evidence was genuinely new in the relevant sense (available or readily obtainable at trial) and whether it would likely have changed the trial judge’s assessment of the chain of custody and the reliability of the prosecution’s evidence.
What Was the Outcome?
The Court of Appeal dismissed Sanjay’s application in Criminal Motion No 23 of 2022 and dismissed both appeals (CCA 30 and CCA 32). It upheld the convictions of Dzulkarnain and Sanjay on the capital drug charges brought against them.
As to sentence, the Court of Appeal upheld the High Court’s sentencing outcomes: Dzulkarnain’s alternative sentence of life imprisonment (because the Prosecution had issued him a certificate of substantive assistance), and Sanjay’s mandatory sentence of death (because no CSA was issued to him). The Court therefore affirmed the practical effect that Dzulkarnain would not be subject to caning due to his age, while Sanjay remained liable to the mandatory capital sentence.
Why Does This Case Matter?
Dzulkarnain bin Khamis v Public Prosecutor is significant for practitioners because it reaffirms how appellate courts approach (i) identity and continuity in drug exhibit cases, (ii) challenges to admissibility and the alleged reliance on inadmissible statements, and (iii) the evidential burden of rebutting the s 18(2) presumption under the MDA. The decision illustrates that where the trial judge’s findings are grounded in surveillance observations, location-based evidence, and the overall coherence of the prosecution narrative, appellate intervention is unlikely.
The case also provides practical guidance on the limits of “fresh evidence” applications in criminal appeals. The Court’s refusal to admit Sanjay’s proposed evidence underscores that the threshold is not merely whether the evidence could be relevant, but whether it is genuinely new in the required sense and whether it would likely have altered the outcome. Defence counsel seeking remittal for further evidence must therefore carefully evaluate both availability at trial and materiality to the core elements of the offence.
From a sentencing perspective, the decision also highlights the operational importance of the certificate of substantive assistance (CSA). Dzulkarnain’s receipt of a CSA resulted in the alternative sentence of life imprisonment, whereas Sanjay’s lack of a CSA meant the mandatory death sentence remained. This reinforces the need for early and strategic engagement with the substantive assistance process in capital drug cases, as it can be determinative of sentencing outcomes even where convictions are upheld.
