Summary
The judgment in [2020] SGCA 45 represents a significant appellate affirmation of convictions in complex drug trafficking operations where the primary orchestrators and suppliers are not apprehended at the immediate scene of the transaction. The Court of Appeal was tasked with reviewing the convictions of Mohammad Rizwan bin Akbar Husain (“Rizwan”) and Saminathan Selvaraju (“Saminathan”), both of whom were sentenced to death following a joint trial in the High Court. The case arose from a Central Narcotics Bureau (“CNB”) operation on 20 November 2013, involving the seizure of 301.6g of diamorphine. Unlike the courier, Zulkarnain bin Kemat (“Zulkarnain”), who was arrested with the drugs in his vehicle, Rizwan and Saminathan were identified and arrested through subsequent investigations—Rizwan after fleeing to Malaysia and Saminathan through border records and vehicle identification.
The appellate result was a total dismissal of the appeals against conviction and the accompanying criminal motions to adduce fresh evidence. The court’s decision reinforces the robust application of circumstantial evidence in establishing the elements of abetment by instigation under the Misuse of Drugs Act (“MDA”). For Rizwan, the prosecution relied on his presence at the scene in a vehicle registered to him, his communications with the courier, and his subsequent flight from Singapore as evidence of his role as the instigator. For Saminathan, the case turned on the reliability of identification evidence linking him to the Malaysian-registered trailer that delivered the drugs to Zulkarnain. The judgment clarifies that while the prosecution must prove every element beyond a reasonable doubt, a cohesive web of circumstantial facts—including post-offence conduct—can be sufficient to sustain a capital conviction.
Doctrinally, the case is notable for its treatment of the "fresh evidence" rule in criminal proceedings. Both appellants sought to introduce alibi evidence and other materials on appeal that were not presented at trial. The Court of Appeal applied the stringent three-step test derived from Ladd v Marshall and affirmed in Public Prosecutor v Mohd Ariffan bin Mohd Hassan, emphasizing that the requirement of "non-availability" is not easily bypassed, especially when the evidence was within the knowledge of the accused at the time of the trial. The court’s refusal to admit this evidence underscores the finality of trial processes and the high threshold required to disturb a conviction based on materials that could have been produced earlier.
The broader significance of this case lies in its illustration of the evidentiary challenges and judicial rigour involved in "non-arrest-at-scene" drug prosecutions. It serves as a reminder to practitioners that the absence of a "smoking gun" arrest does not preclude a conviction if the circumstantial trail is sufficiently dense. The court’s detailed analysis of vehicle movements, border crossing timings, and the conduct of the accused provides a blueprint for how the prosecution may bridge the gap between a physical drug seizure and the higher-level participants in a trafficking conspiracy.

What Were the Facts of This Case?
The factual matrix centers on a coordinated drug delivery on the night of 20 November 2013. The primary actors were Zulkarnain (the courier), Rizwan (the alleged instigator), and Saminathan (the alleged supplier/driver). The CNB had placed Zulkarnain under surveillance starting at 8:15 PM. He was observed driving a black Honda (SGE 8448Z) from Spooner Road to the vicinity of Chin Bee Drive and Quality Road. At approximately 9:55 PM, a black Mitsubishi Lancer (SGC 4606C) was seen in the same area. This Mitsubishi was registered to Rizwan. Surveillance officers noted that the driver of the Mitsubishi appeared to be a "plump" man wearing a cap, a description that the prosecution later linked to Rizwan.
The transaction took place at Quality Road. A Malaysian-registered trailer (WER 2508) was parked with its hazard lights on. The driver of the trailer alighted and was seen placing items into the left rear passenger side of Zulkarnain’s Honda. Following this exchange, the vehicles dispersed. Zulkarnain was subsequently intercepted at Tagore Industrial Avenue. A search of his vehicle yielded 35 bundles of granular substance, which forensic analysis confirmed contained not less than 301.6g of diamorphine. Zulkarnain’s defense at trial was that he believed the bundles contained "Panadol" or "tobacco," but this was rejected by the trial judge.
Rizwan’s involvement was established through circumstantial links. Although he was not arrested on the night of the transaction, his car (SGC 4606C) was identified at the scene. Furthermore, phone records indicated communications between Rizwan and Zulkarnain. Most critically, Rizwan’s conduct following the arrest of Zulkarnain was highly suspicious. On 25 November 2013, five days after the transaction, Rizwan left Singapore for Malaysia by hiding in the boot of a car, an act he admitted was intended to evade the authorities. He was eventually arrested by Malaysian police and repatriated on 29 November 2013. Rizwan’s defense was a denial of presence at the scene, claiming he had lent his car to a friend named "Apoi" and that his flight to Malaysia was due to unrelated fears of being framed for a different matter.
Saminathan was identified as the driver of the trailer WER 2508. The prosecution relied on records from the Immigration and Checkpoints Authority (“ICA”) and the trailer’s owner, MKG Enterprises. The records showed that Saminathan had driven the trailer into Singapore on the day of the offence. Saminathan was not arrested until 25 March 2014, when he attempted to enter Singapore. His defense was an alibi; he claimed he was not the driver of the trailer on that specific night and that he had been at home in Malaysia. He challenged the reliability of the identification evidence and the ICA records, suggesting that another driver could have used his work permit or the trailer.
The High Court judge, in [2018] SGHC 161, found the prosecution’s case proved against all three. Zulkarnain was sentenced to life imprisonment and 15 strokes of the cane, having received a certificate of substantive assistance under s 33B of the Misuse of Drugs Act. Rizwan and Saminathan, however, did not receive such certificates and were sentenced to the mandatory death penalty. Both appealed their convictions, and both filed motions to introduce new evidence that they claimed would prove their innocence or at least create reasonable doubt regarding their presence at the scene.
What Were the Key Legal Issues?
The appeals raised several critical legal issues concerning both the substantive law of drug trafficking and the procedural law of evidence:
- Abetment by Instigation: Whether the prosecution had proved that Rizwan "instigated" Zulkarnain to possess the diamorphine for the purpose of trafficking under s 5(1)(a) read with s 12 of the MDA. This required an analysis of whether Rizwan’s actions constituted active encouragement or command.
- Identification Evidence: Whether the identification of Saminathan as the driver of the trailer WER 2508 was sufficiently reliable to support a conviction, given that no CNB officer could positively identify his face at the scene.
- Admissibility of Fresh Evidence: Whether the evidence sought to be adduced in Criminal Motion Nos 4 and 11 of 2019 satisfied the three-pronged test in Ladd v Marshall:
- Non-availability (the evidence could not have been obtained with reasonable diligence for use at the trial);
- Relevance and Credibility (the evidence is such that, if given, it would probably have an important influence on the result of the case, though it need not be decisive); and
- Reliability (the evidence must be such as is presumably to be believed).
- Corroboration of Accomplice Evidence: The extent to which the court should rely on the statements of Zulkarnain (a co-accused) against Rizwan and Saminathan, and whether the Baskerville test for corroboration was applicable.
- Presumptions under the MDA: The application of the presumption of knowledge under s 18(2) and the presumption of possession for trafficking, and whether they could be invoked simultaneously in light of Zainal bin Hamad v Public Prosecutor.
How Did the Court Analyse the Issues?
The Court of Appeal, in a judgment delivered by Tay Yong Kwang JA, systematically addressed the substantive appeals and the criminal motions. The analysis began with the motions for fresh evidence, as the outcome of these motions would determine the evidentiary record for the appeals.
The Motions for Fresh Evidence
Rizwan sought to call a new witness, Mohammed Farhan bin Baharudin (“Farhan”), who claimed that he, not Rizwan, was the "plump" man in the cap at the scene. Saminathan sought to introduce alibi evidence from his mother and sister, as well as expert evidence regarding trailer GPS data. The Court applied the Ariffan test, which incorporates the Ladd v Marshall criteria. Regarding Rizwan’s motion, the Court found that Farhan’s evidence failed the "non-availability" limb. Rizwan knew Farhan at the time of the trial, yet Farhan was never mentioned in Rizwan’s defense. The Court noted that the "proportionality" of admitting fresh evidence (as discussed in Rahmat v Public Prosecutor) did not override the fundamental requirement of diligence. The Court held at [59] that the proportionality of admitting fresh evidence must be considered, but here, the evidence was not truly "fresh" and lacked credibility.
For Saminathan, the Court similarly rejected the alibi evidence from his family members. The Court observed that if Saminathan had truly been at home, he would have known this at the time of the trial. The failure to raise this alibi during the trial was fatal. The Court emphasized that the Ariffan conditions are "stringent" to prevent the trial process from becoming a "dress rehearsal."
Rizwan’s Conviction: Abetment by Instigation
The Court examined the law on abetment, citing [2012] SGCA 18. Abetment by instigation requires that the accused "actively suggested, encouraged, or stimulated" the commission of the offence. The Court found that Rizwan’s presence at the scene in his own car, coupled with his communications with Zulkarnain, pointed irresistibly to his role as the coordinator. The Court rejected Rizwan’s "Apoi" defense as a "bare denial" and a "fabrication."
Crucially, the Court addressed the significance of Rizwan’s flight to Malaysia. While flight alone is not proof of guilt, the Court held that the circumstances of Rizwan’s departure—hiding in a car boot shortly after the drug bust—constituted post-offence conduct that strongly supported an inference of guilty knowledge. The Court noted that Rizwan’s explanation for his flight was inconsistent and lacked any supporting evidence.
Saminathan’s Conviction: Identification and Delivery
Saminathan’s appeal turned on whether he was the driver of the trailer WER 2508. The Court relied on a "combination of factors" to uphold the identification. First, the ICA records showed Saminathan entering Singapore with that specific trailer on the night of the offence. Second, the owner of the trailer, Murugan, testified (via a statement admitted under s 32(1)(k) of the Evidence Act) that Saminathan was the assigned driver for that trailer. The Court found that the probability of another person using Saminathan’s work permit and driving the trailer into Singapore at the exact time of a major drug transaction was "negligible."
The Court also considered the Baskerville test regarding the evidence of Zulkarnain. While Public Prosecutor v Mohammed Liton Mohammed Syeed Mallik [2008] 1 SLR(R) 601 established that the Baskerville test (requiring independent corroboration for accomplice evidence) does not strictly apply to the evidence of a co-accused in the same trial, the Court nonetheless exercised caution. It found that Zulkarnain’s identification of Saminathan was corroborated by the objective ICA and vehicle records.
Presumptions and Mens Rea
The Court addressed the interplay of presumptions under the MDA. Following Zainal bin Hamad v Public Prosecutor [2018] 2 SLR 1119, the Court noted that the prosecution cannot rely on both the presumption of possession (s 18(1)) and the presumption of knowledge (s 18(2)) simultaneously to prove the same element. However, in this case, the Court found that the prosecution had proved Rizwan’s knowledge of the nature of the drugs (diamorphine) through circumstantial evidence, specifically his role as the instigator of a high-value transaction, which made it "inconceivable" that he did not know the nature of the contraband.
"For the above reasons, we affirm Rizwan’s and Saminathan’s convictions on their respective charges." (at [119])
What Was the Outcome?
The Court of Appeal dismissed both Criminal Appeal No 9 of 2018 and Criminal Appeal No 13 of 2018. The convictions of Mohammad Rizwan bin Akbar Husain and Saminathan Selvaraju were affirmed. Consequently, the mandatory death sentences imposed by the High Court remained in force. The Court also dismissed Criminal Motion No 4 of 2019 and Criminal Motion No 11 of 2019, refusing to admit the fresh evidence tendered by the appellants.
The operative conclusion of the Court was stated as follows:
"Accordingly, Rizwan’s appeal in CCA 9/2018 and Saminathan’s appeal in CCA 13/2018 are dismissed." (at [119])
Regarding the co-accused Zulkarnain, his sentence of life imprisonment and 15 strokes of the cane (imposed at trial) was not the subject of this specific appellate judgment, as he had been sentenced under the alternative sentencing regime in s 33B of the MDA. The Court noted that the trial judge had correctly sentenced Zulkarnain to life imprisonment with effect from the date of his arrest, following the issuance of a certificate of substantive assistance by the Public Prosecutor.
The Court ordered that the convictions for the following charges be upheld:
- Rizwan: Abetment by instigating Zulkarnain to be in possession of not less than 301.6g of diamorphine for the purpose of trafficking, an offence under s 5(1)(a) read with s 5(2) and s 12 of the MDA.
- Saminathan: Trafficking in not less than 301.6g of diamorphine by delivering the drugs to Zulkarnain, an offence under s 5(1)(a) of the MDA.
No orders as to costs were made, as is standard in criminal appeals of this nature in Singapore.
Why Does This Case Matter?
This judgment is a cornerstone for understanding the evidentiary requirements in "non-arrest-at-scene" drug trafficking cases. It clarifies how the Singapore courts bridge the gap between the physical seizure of drugs from a courier and the criminal liability of those who orchestrated or supplied the delivery. The case matters for several reasons:
1. Strict Enforcement of the Fresh Evidence Rule: The Court of Appeal’s refusal to admit alibi evidence that was known to the accused during the trial serves as a stern warning to defense counsel. It reinforces the principle that the trial is the primary forum for determining facts. Practitioners cannot "reserve" evidence for the appeal or seek a "second bite at the cherry" by introducing witnesses who were available but not called during the initial trial. The application of Ladd v Marshall in the criminal context remains uncompromising.
2. Circumstantial Proof of Instigation: The case provides a detailed look at what constitutes "instigation" under s 12 of the MDA. By affirming Rizwan’s conviction based on his presence at the scene, his communications, and his subsequent flight, the Court has signaled that "instigation" does not require a recorded command or direct testimony of a verbal order. It can be inferred from the totality of the accused’s conduct and his relationship with the principal offender.
3. Reliability of Border and Vehicle Records: Saminathan’s conviction highlights the weight the court accords to objective records such as ICA entry/exit logs and employer vehicle assignments. In the absence of a positive facial identification by surveillance officers, these records—when combined with the testimony of the courier—can be sufficient to prove identity beyond a reasonable doubt. This is particularly relevant in the context of cross-border trafficking involving Malaysian-registered vehicles.
4. Flight as Evidence of Guilty Mind: The judgment reaffirms that while flight is not a "presumption" of guilt, it is a potent piece of circumstantial evidence. Rizwan’s elaborate escape to Malaysia (hiding in a car boot) was treated as highly probative of his involvement in the drug transaction. This underscores the importance of post-offence conduct in the court’s assessment of mens rea.
5. Interplay of Co-accused Statements: The Court’s treatment of Zulkarnain’s evidence against his co-accused illustrates the nuanced approach to accomplice testimony. While the Baskerville requirement for independent corroboration is not a strict rule of law for co-accused, the Court’s insistence on finding "objective support" for such testimony ensures that convictions are not based solely on the word of one criminal against another.
Practice Pointers
- Early Disclosure of Alibi: Defense counsel must identify and disclose alibi witnesses at the earliest possible stage. Failure to call an alibi witness at trial almost certainly precludes their testimony on appeal under the Ariffan "non-availability" limb.
- Scrutinizing ICA and GPS Data: In cases involving cross-border deliveries, practitioners should rigorously audit ICA records and vehicle GPS data. Any discrepancy in timing or vehicle assignment can be the key to creating reasonable doubt regarding identification.
- Explaining Post-Offence Conduct: If an accused has fled the jurisdiction or behaved suspiciously after an offence, counsel must provide a credible, evidence-backed explanation for such conduct early in the proceedings to neutralize the inference of a "guilty mind."
- Challenging Co-accused Credibility: While Mohammed Liton relaxes the corroboration rule, counsel should still focus on the "cautionary rule" and seek to highlight inconsistencies between a co-accused’s statement and objective circumstantial evidence.
- Abetment Strategy: For charges under s 12 MDA, the defense should focus on breaking the link between the accused’s presence and the "active stimulation" required for instigation. Mere presence or association is insufficient; the prosecution must prove a "command" or "encouragement."
- Fresh Evidence Motions: When filing a motion to adduce fresh evidence, counsel must specifically address why the evidence was not available at trial. Vague assertions of "oversight" or "newly discovered" witnesses will not suffice if the witnesses were known to the accused previously.
Subsequent Treatment
The ratio in this case regarding the admissibility of fresh evidence has been consistently followed in subsequent criminal appeals, reinforcing the high threshold established in Ariffan. The Court of Appeal’s approach to circumstantial evidence and the inference of guilty knowledge from flight continues to be a point of reference in drug trafficking cases where the "kingpins" or "coordinators" are not caught red-handed. The case is frequently cited for the proposition that the Baskerville test does not strictly apply to co-accused, though a rule of prudence and caution remains necessary.
