Muhammad Zaim Bin Awang v Pendakwa Raya

Case Significance

Illustrates the appellate treatment of common evidential challenges in a drug-trafficking appeal — chain of custody, the statutory caution, possession and the section 37(da) presumption: where the trial court's findings are supported by the evidence and the integrity of the exhibits is established, the conviction stands, and a co-accused's acquittal does not disturb it.

This Court of Appeal decision concerns an appeal against a conviction for trafficking cannabis in which a range of evidential and procedural challenges were rejected. The appellant and his wife had been charged with trafficking 1,199.3 grams of cannabis under seksyen 39B(1)(a) Akta Dadah Berbahaya 1952 (section 39B(1)(a) of the Dangerous Drugs Act 1952). At the close of the prosecution case the appellant's wife was acquitted and discharged, but the appellant was called to enter his defence and, at the end of the trial, was found guilty and sentenced to life imprisonment with fifteen strokes of the cane. His appeal challenged the conviction and sentence on several fronts: that the drug exhibits had been compromised so that the chain of custody was broken; that no statutory caution had been administered; that possession had not been proved; that the presumption of trafficking under section 37(da) had been improperly invoked; and that the investigations were defective. The Court of Appeal examined each complaint and rejected it. It held that the trial judge had correctly found the chain of custody to be intact and that the caution had been given, and that the trial court had arrived at findings fully supported by the evidence, so that the conviction was safe and warranted no appellate intervention. It accordingly dismissed the appeal against conviction and sentence and affirmed the decision of the High Court. The judgment is a useful illustration of the appellate treatment of common evidential challenges in a drug-trafficking appeal — chain of custody, the statutory caution, possession and the section 37(da) presumption: where the trial court's findings on these matters are supported by the evidence and the integrity of the exhibits is established, the conviction will stand, and the acquittal of a co-accused does not disturb the safety of the appellant's own conviction.
