Summary
In Mohammad Rizwan bin Akbar Husain v Public Prosecutor ([2020] SGCA 45), the Court of Appeal dealt with two related drug trafficking prosecutions arising from a surveillance operation conducted by the Central Narcotics Bureau (CNB) on 20 November 2013. Rizwan and Saminathan were not arrested at the scene of the drug transaction; instead, they were apprehended later—Rizwan about eight days afterwards and Saminathan about four months afterwards. Both were convicted in the High Court for offences under the Misuse of Drugs Act (MDA) involving diamorphine, with Rizwan charged as an abettor by instigating a courier to possess the drugs for trafficking, and Saminathan charged as a trafficker by delivering the drugs to the courier.
The Court of Appeal upheld the convictions. A central theme was whether the evidence proved the requisite knowledge and intention for the respective roles attributed to Rizwan and Saminathan. The court also addressed the procedural and evidential requests made through criminal motions to adduce additional evidence on appeal, including alibi evidence and other categories of material not tendered at trial. The court dismissed the motions and affirmed the High Court’s approach to the admissibility and weight of the proposed evidence.
What Were the Facts of This Case?
The prosecutions stemmed from CNB surveillance of a suspect, Zulkarnain bin Kemat, on the night of 20 November 2013. Officers placed Zulkarnain under surveillance at about 8.15pm and tailed him from his residence at Spooner Road until he reached Chin Bee Drive at about 9.13pm. At that point, Zulkarnain was driving a black Honda car. The surveillance then tracked the movements of multiple vehicles in the vicinity of Chin Bee Drive and Quality Road, including a black Mitsubishi Lancer registered in Rizwan’s name.
At about 9.55pm, CNB observed Zulkarnain positioning his car close to the junction of Chin Bee Drive and Quality Road. A black Mitsubishi Lancer (registration number SGC4606C) was parked in front of Zulkarnain’s car. The driver of the Mitsubishi was observed to be “plump” and wearing a cap. The Mitsubishi then moved together with Zulkarnain’s car into Quality Road. CNB also observed a stationary trailer along Quality Road, bearing Malaysian registration number WER 2508, with hazard lights turned on.
The key exchange occurred when the trailer driver alighted and placed items into Zulkarnain’s car through the left rear passenger side. After that, all three vehicles left Quality Road and were separately tailed. Zulkarnain’s car was later stopped at Tagore Industrial Avenue, where CNB arrested him. A search of Zulkarnain’s car revealed two sets of black-taped bundles—15 bundles in one red plastic bag and 20 bundles in another—amounting to 35 bundles. These bundles formed the subject matter of the charges against the three accused.
After the arrest of Zulkarnain, CNB continued to investigate the involvement of Rizwan and Saminathan. Rizwan was not arrested at the scene. Instead, he left Singapore for Malaysia on 25 November 2013, hiding in the boot of a car, and was later apprehended by Malaysian authorities. He was brought back to Singapore and arrested at Woodlands Checkpoint on 29 November 2013. Saminathan, likewise, was not arrested at the scene. He was identified as the driver of the trailer using ICA records and was arrested on 25 March 2014 when he entered Singapore and was handed over to CNB.
What Were the Key Legal Issues?
The first major issue concerned whether the evidence established the elements of the MDA offences beyond a reasonable doubt, particularly for Rizwan’s conviction as an abettor. Abetment by instigation requires proof that the accused intentionally encouraged or caused the principal offender to commit the relevant offence. In Rizwan’s case, the court had to determine whether the prosecution proved that Rizwan had knowledge that the drugs were diamorphine and that he intended the principal (Zulkarnain) to possess the drugs for the purpose of trafficking.
The second major issue concerned Saminathan’s conviction for trafficking by delivering the drugs to Zulkarnain. Trafficking under the MDA is broad and can include delivery. The court had to assess whether the evidence—particularly identification evidence linking Saminathan to the trailer and the delivery—was reliable and whether the prosecution proved the requisite connection between Saminathan’s conduct and the delivery of the diamorphine to Zulkarnain.
Finally, the court had to address the criminal motions to adduce additional evidence. These motions raised questions about the circumstances in which an appellate court should admit fresh evidence, including alibi evidence and other categories of material that were not tendered at trial. The court had to consider whether the proposed evidence met the threshold for admission and, if admitted, whether it would likely affect the outcome.
How Did the Court Analyse the Issues?
The Court of Appeal approached the appeals by examining, first, the evidential foundation for each accused’s role and, second, the procedural propriety of the motions to adduce additional evidence. The court noted that the cases were “unusual” because neither Rizwan nor Saminathan was arrested at the scene of the drug transaction. This meant that the prosecution’s case depended heavily on circumstantial evidence, identification evidence, and the content and reliability of statements made during investigations, rather than on direct in-scene arrest evidence.
For Rizwan, the court focused on whether the prosecution proved knowledge and intention in relation to diamorphine and trafficking. The charge against Rizwan was framed as abetment by instigating Zulkarnain to be in possession for trafficking. The court therefore scrutinised whether Rizwan’s conduct and statements (as presented at trial) supported an inference that he was not merely associated with the vehicles or the logistics, but was actively involved in instigating the courier to collect and transport the drugs. In particular, the court analysed whether the evidence showed that Rizwan knew the nature of the controlled drug and intended the transaction to be for trafficking.
For Saminathan, the court’s analysis centred on identification and the evidential link between Saminathan and the delivery of the drugs. The prosecution relied on identification evidence derived from ICA records identifying Saminathan as the driver of the trailer on the relevant date. The court also considered the trial evidence concerning the circumstances of the delivery—namely, that the trailer driver placed items into Zulkarnain’s car through the left rear passenger side. The Court of Appeal assessed whether the identification evidence was sufficiently reliable and whether it, together with the other evidence, proved that Saminathan delivered the diamorphine to Zulkarnain.
In addition to the substantive elements, the Court of Appeal addressed the motions. Rizwan’s motion sought leave to adduce alibi evidence through testimony from a witness, Mohammed Farhan bin Baharudin (“Farhan”). Saminathan’s motion sought leave to adduce multiple categories of evidence: alibi testimony from his mother and sister; statements made to police and other documents not tendered at trial; and communications between his counsel and an expert witness engaged for the defence. The Court of Appeal dismissed these motions, indicating that the proposed evidence did not meet the requirements for admission on appeal, and/or that it would not materially undermine the prosecution’s case as found by the High Court.
Although the provided extract is truncated, the structure of the judgment indicates that the court gave reasons after hearing the substantive appeals, and that it treated the motions as distinct from the merits. The court’s reasoning would have included considerations such as whether the evidence was truly “fresh” (in the sense of not available or not reasonably obtainable at trial), whether it was credible and relevant, and whether it would likely have affected the trial outcome. The court’s dismissal of both motions meant that the appellate review proceeded on the trial record and the evidence already accepted by the High Court.
What Was the Outcome?
The Court of Appeal dismissed the appeals and affirmed the High Court’s convictions of both Rizwan and Saminathan. The practical effect was that the mandatory death sentences imposed by the High Court on Rizwan and Saminathan remained in place, subject to the legal consequences of the appellate decision.
The court also dismissed the criminal motions seeking leave to adduce additional evidence. This meant that the appellate court did not supplement the trial record with the proposed alibi and other materials, and the convictions were upheld on the basis of the evidence already before the High Court.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how the Court of Appeal evaluates drug trafficking cases where the accused are not arrested at the scene. In such situations, the prosecution’s burden is often met through a combination of surveillance evidence, vehicle and identification links, and the accused’s statements or conduct after the transaction. The decision reinforces that courts will carefully scrutinise whether circumstantial evidence supports the specific statutory elements—particularly knowledge and intention for abetment, and reliable identification for delivery-based trafficking.
Second, the case is a useful reference point on the approach to criminal motions to adduce fresh evidence on appeal. Defence counsel often seek to introduce alibi evidence or additional documents after conviction. The dismissal of both motions underscores that appellate admission is not automatic and that courts will require a persuasive justification for why the evidence was not (or could not reasonably have been) presented at trial, as well as an assessment of its likely impact on the verdict.
Third, the judgment sits within the broader MDA sentencing framework concerning courier liability and substantive assistance certificates. While Zulkarnain received life imprisonment because the Public Prosecutor issued a certificate of substantive assistance under s 33B(2)(a), Rizwan and Saminathan did not receive such certificates under s 33B(2)(b). The case therefore highlights the procedural and evidential importance of substantive assistance mechanisms and the consequences of how the prosecution exercises discretion in issuing certificates.
