Summary
In Public Prosecutor v Lokman bin Abdul Rahman & another ([2020] SGHC 48), the High Court dealt with two brothers charged in connection with the possession and trafficking of diamorphine under the Misuse of Drugs Act (Cap 185, 2008 Rev Ed) (“MDA”). The prosecution’s case was that Lokman was a courier acting under the instructions of his brother, Mubin, who was the principal drug trafficker. Lokman, by contrast, claimed that he was merely helping Mubin and that Mubin was the trafficker. Mubin’s position was the reverse: that Lokman was the trafficker and that Mubin had no role in the drug business.
The court’s decision turned on a central factual issue: who ran the drug trafficking operation and, in particular, whether the two bundles of diamorphine found in Lokman’s possession were delivered to Mubin (and then retrieved by Lokman) or delivered to Lokman (and then retrieved by Mubin). After assessing the evidence and the credibility of the competing narratives—especially around delivery events and communications after Lokman’s arrest—the court accepted the prosecution’s version. It found that the facts reflected the scenario that Mubin was the trafficker and Lokman was acting as a courier.
Accordingly, both accused were convicted on amended charges. Lokman was sentenced to life imprisonment, while Mubin received the mandatory death sentence for the relevant MDA offence. The judgment is significant for its careful treatment of (i) the elements of trafficking by possession for the purpose of trafficking, (ii) abetment by instigation under the MDA, and (iii) how courts resolve factual disputes where both accused offer mutually exclusive accounts.
What Were the Facts of This Case?
On 8 September 2015 at about 10.30pm, Central Narcotics Bureau (“CNB”) officers arrested Lokman at the ground floor lift lobby of Katong Park Towers (“KPT”), 114A Arthur Road. Lokman was carrying a black bag containing, among other things, two bundles of diamorphine later marked A1E1A and A1F1A. The drug analysis and chain of custody were not disputed. A1E1A contained not less than 19.88g of diamorphine and A1F1A contained not less than 19.40g of diamorphine, which together formed the subject matter of the trafficking charges.
Beyond the two bundles forming the core charges, other drugs were found in Lokman’s possession. In the black bag were five additional packets of diamorphine and 50 tablets of ethylone and methoxetamine. A further five packets of diamorphine and three packets of methamphetamine were recovered from another bag carried by Lokman. These additional items provided contextual evidence about the nature and scale of the activities in which Lokman was involved.
After his arrest, Lokman was brought to #08-06 South Tower at KPT (“the KPT Unit”), where he was residing. A search was conducted there and multiple drug-related items were recovered, including diamorphine packets, methamphetamine, black tape, and other materials consistent with drug handling or packaging. The tenancy documents indicated that the KPT Unit was rented to Mubin and one Siti Rohani binte Mohamed Ali, and the monthly rental was paid by Mubin. On the night of Lokman’s arrest, Tihani binte Ibrahim (Mubin’s girlfriend) and her infant son were at the unit.
Mubin was arrested later on 5 October 2015 at M28 Minimart, Blk 182A Rivervale Crescent. At the time of his arrest, CNB found on him two packets of methamphetamine, three packets of diamorphine, empty sachets, and a weighing scale. After Lokman’s arrest, CNB officers also supervised Lokman’s use of his mobile phone to communicate with “Edy” and Mubin. These conversations were recorded, transcribed, and translated, and they became important evidence in assessing the credibility of Lokman’s and Mubin’s accounts.
What Were the Key Legal Issues?
The first legal issue concerned Lokman’s liability under the MDA for trafficking. Under s 5(1)(a) read with s 5(2) of the MDA, the prosecution had to prove that Lokman had possession of the controlled drug, knew the nature of the drug, and that his possession was for the purpose of trafficking (and was not authorised). The statutory definition of “traffic” in s 2 includes acts such as deliver or distribute, and s 5(2) provides that possession for the purpose of trafficking constitutes the trafficking offence.
The second legal issue concerned Mubin’s liability for abetment by instigation. Mubin faced a charge under s 12 of the MDA, which provides that any person who abets the commission of an offence under the MDA is guilty of that offence and liable to the punishment provided for it. The meaning of “abets” is taken from s 107 of the Penal Code, and the court identified that abetment by instigation requires proof of (i) the actus reus of instigation—active suggestion, support, stimulation or encouragement—and (ii) the mens rea—intention that the person abetted perform the act abetted, together with knowledge of the circumstances constituting the offence.
Finally, the case raised a crucial evidential issue: where two accused present mutually exclusive narratives about who was the principal trafficker and who was merely assisting, the court must decide which account is credible. This factual determination directly affected both Lokman’s “purpose” element and Mubin’s instigation element.
How Did the Court Analyse the Issues?
The court began by setting out the statutory elements for trafficking and the doctrinal requirements for abetment by instigation. For trafficking under s 5(1)(a) read with s 5(2), the court reiterated that the prosecution must establish possession, knowledge of the nature of the drug, and that the possession was for the purpose of trafficking. The judgment also noted that the prosecution had an alternative reliance on presumptions under the MDA (including s 17), but the central contest remained whether Lokman’s possession was for trafficking and whether the evidence supported the prosecution’s narrative of delivery and instruction.
On the factual plane, the court identified the “central factual issue” as the question of who ran the drug business. This was not merely a character assessment; it was tied to specific delivery and instruction events. The judgment focused on the supply of diamorphine and, in particular, whether the two bundles in Lokman’s possession came from “Zaini”, and when and how the bundles were delivered. The court examined competing accounts about delivery dates and locations, including deliveries said to have occurred on 7 September 2015 (the Marina Bay Sands (“MBS”) delivery), 5 September 2015 (the carpark delivery), and 1 September 2015. These events mattered because they helped determine whether the bundles were meant for Mubin’s distribution network or for Lokman’s independent role.
The court also scrutinised the question whether Zaini delivered to Mubin or to Lokman. This distinction was central to the prosecution’s theory that Mubin was the principal trafficker who arranged for the drugs to be retrieved and delivered by Lokman. The court’s reasoning indicates that it treated the delivery chain as a proxy for control: the person who received the drugs and gave instructions was more likely to be the one running the trafficking operation. In contrast, if the drugs were delivered to Lokman, the inference would shift towards Lokman being the principal actor.
In assessing credibility, the court analysed communications after Lokman’s arrest. The CNB-supervised phone calls and messages between Lokman, “Edy”, and Mubin were treated as contemporaneous evidence that could corroborate or undermine the accused’s narratives. The court also evaluated Lokman’s testimony about 8 September 2015, including alleged contradictions within his evidence and contradictions with other evidence. The judgment further considered possible motives to falsely implicate Mubin, recognising that in cases involving close family relationships and mutually incriminating narratives, credibility analysis must be careful and evidence-driven.
As to Mubin’s account, the court assessed his narrative about his role (or lack of role) in the drug business. It examined whether Mubin’s explanations were consistent with the surrounding evidence, including whether he was familiar with the relevant persons (“Zaini” and “Noor”), whether he was a regular at the KPT unit, and whether his conduct and communications aligned with a person who was merely uninvolved. The court also considered phone evidence, including Lokman’s phone identified as “L-HP1”, as part of the broader evidential matrix.
Ultimately, the court concluded that the facts reflected the former scenario—Mubin as the drug trafficker and Lokman as the courier—rather than the latter scenario advanced by Mubin. This conclusion was not reached in isolation; it was the product of integrating (i) the delivery chain and timing, (ii) the evidence of possession and handling at the KPT unit, (iii) the recorded communications after arrest, and (iv) the court’s evaluation of credibility and internal consistency.
What Was the Outcome?
After evaluating the evidence, the court convicted both accused on amended charges. Lokman was sentenced to life imprisonment. The mandatory death sentence was imposed on Mubin, reflecting the court’s finding that Mubin was the principal actor who instigated Lokman to traffic in the controlled drug.
Practically, the outcome demonstrates how the court’s determination of the “who instructed whom” question can be decisive for sentencing outcomes under the MDA. The same underlying drug seizure can lead to materially different results depending on whether the accused is found to be a courier acting on instructions or the instigator/principal running the trafficking operation.
Why Does This Case Matter?
This case matters because it illustrates, in a structured and evidence-sensitive way, how Singapore courts apply the MDA’s trafficking framework and the Penal Code-linked concept of “abetment” for MDA offences. For practitioners, the judgment is a useful reference on how courts approach the elements of trafficking by possession for the purpose of trafficking, particularly where the accused’s knowledge and possession are not the only contested matters; the “purpose” element often depends on contextual evidence and credibility.
It is also significant for its treatment of abetment by instigation. The court’s analysis underscores that instigation requires both an actus reus (active suggestion, support, stimulation or encouragement) and mens rea (intention and knowledge). In this case, the court’s factual findings about delivery and instruction were effectively the bridge between the evidence and the legal requirements for instigation.
From a research and litigation perspective, the judgment provides a detailed model for evaluating competing narratives in drug trafficking cases involving close relationships. The court’s reliance on contemporaneous communications after arrest, its focus on delivery timing and sourcing, and its methodical credibility assessment are all practical tools for counsel preparing submissions on whether an accused was a principal or a courier.
