Summary
Public Prosecutor v Saridewi Bte Djamani and another concerned joint charges under the Misuse of Drugs Act (“MDA”) relating to diamorphine trafficking. The first accused, Saridewi, was charged under s 5(1)(a) read with s 5(2) of the MDA for possession of six packets and seven straws containing not less than 30.72 grams of diamorphine, a Class A controlled drug. The second accused, Haikal, was charged under s 5(1)(a) for delivering two packets containing not less than 28.22 grams of diamorphine to Saridewi.
The High Court (See Kee Oon J) found that the Prosecution proved the charges beyond reasonable doubt. The court accepted the integrity of the chain of exhibits and the forensic findings on drug quantity and DNA. It also applied the statutory presumptions of trafficking and knowledge under the MDA, concluding that the accused persons failed to rebut those presumptions on the required balance of probabilities. Saridewi’s defence—centred on claimed personal consumption and alleged mental incapacity affecting the accuracy of her statements—was rejected. Haikal’s defence similarly failed, particularly in light of his own admissions and the suspicious pattern of deliveries.
What Were the Facts of This Case?
The case proceeded on an agreed statement of facts tendered pursuant to s 267(1) of the Criminal Procedure Code (“CPC”). The undisputed aspects included the CNB’s operational steps, the arrests, the seizure of exhibits, and the forensic analyses by the Health Sciences Authority (“HSA”) and the Forensic Response Team (“FORT”). The central factual narrative was a drug transaction at Block 350 Anchorvale Road, Singapore, on 17 June 2016 at about 3.35pm.
Haikal arrived at Block 350 by motorcycle. After parking, he retrieved a white plastic bag from the motorcycle and took the lift to the 17th floor. There, he met Saridewi and handed her a white plastic bag. In exchange, Saridewi gave him an envelope marked “10.000”. CCTV footage captured the movements of both accused using the lifts, and this was not disputed during trial.
CNB had received information about a drug transaction at Block 350 and deployed officers covertly. Shortly after Haikal left the area, he was intercepted and arrested. CNB recovered from him an envelope marked “10.000” (later “MHA-1”) containing cash totalling SGD$10,050 and a brown envelope (later “MHA-2”) containing cash totalling SGD$5,500. Three mobile phones were also seized and sent to FORT for analysis.
Meanwhile, CNB officers moved to Saridewi’s unit. Upon hearing movements and voices outside her door, Saridewi threw various items out of the kitchen window. Before CNB could cut through a metal grille gate, she opened the door to allow entry. Inside the unit, CNB seized numerous items consistent with drug handling and packaging, including packets of crystalline substance, glass tubes, a slab of tablets, empty packets and straws, unused envelopes, a digital weighing scale, a heat sealer, and a notebook. CNB also recovered, from the adjacent construction site and the ground floor of Block 350, multiple plastic bags and packets containing granular/powdery substances and crystalline substances, including packets and straws later marked as A1, A1A, A1A1, A1A2, A1A1A, A1A2A, B1, C1, D1A, D2A, and D3A. The court noted that the integrity and custody of all exhibits were not compromised at any point.
The HSA analysed the exhibits and found that the total amount of diamorphine in the charged exhibits was not less than 30.72 grams. DNA analysis further showed Haikal’s DNA profile on the exterior and interior surface of exhibit “B1” (the two stained packets). Seven investigation statements were recorded from Haikal and Saridewi. While voluntariness was not challenged, both accused challenged the accuracy of certain portions of their statements.
What Were the Key Legal Issues?
The first key issue was whether the Prosecution proved, beyond reasonable doubt, that Saridewi had in her possession the quantity of diamorphine specified in the charge and that she knew the nature of the drug. This required the court to assess the evidence on possession, the reliability of the chain of exhibits, and the forensic findings on drug quantity and DNA.
The second issue concerned the operation of the statutory presumptions under the MDA. For Saridewi, the court had to determine whether the presumption of trafficking under s 17 applied and, if so, whether she rebutted it. For Haikal, the court had to consider the presumption of knowledge under s 18(2) and whether he rebutted it on a balance of probabilities.
A further issue was evidential: whether Saridewi’s statements to investigators were accurate and what weight should be placed on them, particularly in light of expert evidence from a defence psychologist (Dr Julia Lam) suggesting mental conditions that might impair her ability to give an accurate account. The court also had to consider whether Saridewi’s claimed defence of consumption was credible in the face of the quantity of drugs, the packaging materials, and her own admissions.
How Did the Court Analyse the Issues?
On the evidential foundation, the court accepted that the Prosecution’s case was largely supported by undisputed operational and forensic evidence. The agreed statement of facts under s 267(1) CPC meant that the mechanics of the CNB operation, the arrests, and the seizure and analysis of exhibits were not seriously contested. The court emphasised that the integrity and custody of the exhibits were not compromised, which is critical in drug cases where the prosecution must show that the drugs analysed are the same drugs seized and charged.
Regarding the drug transaction, the court relied on the CCTV evidence showing Haikal’s delivery to Saridewi and the exchange of the white plastic bag for the envelope marked “10.000”. It also relied on the cash recovered from Haikal, which corroborated the exchange described by the Prosecution. The DNA evidence further strengthened the link between Haikal and the seized drug-related exhibits, with Haikal’s DNA found on the exterior and interior surfaces of exhibit “B1”.
For Saridewi’s charge, the court’s analysis turned on possession and knowledge. Possession under the MDA can be inferred from circumstances, and here the court had evidence that Saridewi received the drugs, had the drugs and drug paraphernalia in her unit, and attempted to dispose of items when CNB approached. The court also considered the quantity: the charged diamorphine total was not less than 30.72 grams, and the exhibits included multiple packets and straws, consistent with distribution and repackaging rather than mere personal use.
The court then applied the statutory presumption of trafficking under s 17 of the MDA. Once the presumption is triggered, the burden shifts to the accused to rebut it on a balance of probabilities. Saridewi’s defence was that a substantial portion of the diamorphine seized was for her own consumption. She testified that she had relapsed to consuming diamorphine and claimed that she intended to keep some for personal use and the remainder for trafficking. She also argued that the amount intended for trafficking would fall below the threshold of 15 grams for the death penalty under s 33(1) MDA read with the Second Schedule.
The court rejected this defence. While the extract does not reproduce the full reasoning, the judgment’s approach is clear from the court’s findings described in the introduction and the Prosecution’s submissions summarised in the extract. The court accepted the Prosecution’s position that Saridewi was not an abuser of diamorphine at the material time. It also treated her claimed consumption narrative as inconsistent with the evidence of drug handling: the presence of weighing equipment, heat sealer, numerous empty packets and straws, and a notebook suggested active preparation for distribution. The court therefore concluded that Saridewi failed to rebut the presumption of trafficking.
In relation to knowledge, the court also considered Saridewi’s statements. The defence sought to undermine the accuracy of her statements by relying on Dr Lam’s opinion that Saridewi might not have the mental ability to give an accurate version of events due to persistent depressive disorder and severe amphetamine-type substance use disorder. The Prosecution countered that Saridewi was not suffering from drug withdrawal at the time statements were recorded and that there was no substantial impairment of her mental state. The court accepted the Prosecution’s position and placed weight on the accuracy of Saridewi’s statements, rejecting the defence psychologist’s conclusions as flawed in the circumstances.
For Haikal, the court applied the presumption of knowledge under s 18(2) of the MDA. Haikal delivered diamorphine to Saridewi. The Prosecution relied on Haikal’s cautioned statement that he knew what he had passed to Saridewi was “drugs”, and on the fact that he provided contact numbers of individuals associated with “drugs”. The Prosecution also pointed to the pattern of deliveries—Haikal had delivered the same substance to Saridewi on five or six occasions—and that he earned RM500 per delivery. These circumstances made it difficult for Haikal to credibly claim ignorance of the nature of the substance.
The court found that Haikal was unable to rebut the presumption of knowledge on a balance of probabilities. In drug trafficking cases, the court often scrutinises the plausibility of claimed ignorance against the accused’s conduct and admissions. Here, Haikal’s own statement and the repeated, remunerated nature of the deliveries were highly probative. The DNA evidence and the CCTV corroboration further supported the prosecution narrative.
What Was the Outcome?
At the conclusion of the joint trial, the court was satisfied that the Prosecution proved the charges against both accused persons beyond reasonable doubt. Both accused were convicted and sentenced on 6 July 2018. The present judgment sets out the full grounds for conviction.
Practically, the outcome confirms that where the MDA presumptions are triggered—possession of a substantial quantity of a Class A controlled drug and delivery of such drugs—the accused must marshal credible evidence to rebut trafficking and knowledge presumptions. Mere assertions of personal consumption, especially when contradicted by the surrounding evidence of drug handling and packaging, will not suffice.
Why Does This Case Matter?
Public Prosecutor v Saridewi Bte Djamani is significant for practitioners because it illustrates how the High Court evaluates (i) the integrity of exhibits and forensic proof, (ii) the operation of the MDA statutory presumptions, and (iii) challenges to the reliability of investigation statements based on alleged mental conditions. The case demonstrates that courts will scrutinise not only the accused’s testimony but also the objective indicia of trafficking, such as the quantity of drugs, the presence of packaging and processing equipment, and the accused’s conduct during the CNB operation.
From a doctrinal perspective, the decision reinforces that the presumption of trafficking under s 17 and the presumption of knowledge under s 18(2) are powerful prosecutorial tools. Once triggered, the defence bears the burden of rebutting them on a balance of probabilities. The court’s approach indicates that the defence must present evidence that is coherent, consistent with the physical evidence, and capable of raising a reasonable doubt in the court’s mind as to trafficking purpose or knowledge—depending on the presumption in issue.
For sentencing strategy and trial preparation, the case also highlights the practical risks in attempting to “split” quantities between consumption and trafficking to avoid statutory thresholds. Where the evidence supports active repackaging and distribution, courts are unlikely to accept consumption narratives that appear tailored to statutory consequences. Lawyers should therefore focus on building credible, evidence-backed rebuttal cases, including forensic and contextual evidence, rather than relying primarily on the accused’s account.
