AJ-83D-77-01/2024 (Mahkamah Majistret)

Prosecution failed to prove the possession element because it did not exclude access by others to the premises or investigate/co‑call identified persons with regular access (Iqbal and Nasir), and there was no forensic or other incriminating nexus linking the accused to the seized drugs; therefore no prima facie case existed and the accused must be acquitted at the close of the prosecution case.

BA-45A-48-04/2021 (Mahkamah Tinggi)

On maximum evaluation of prosecution evidence the court found identity and quantity of drugs proved by chemical analysis, chain of custody intact notwithstanding minor discrepancies, direct evidence and conduct (possession, flight, admission 'ada' and showing of purple bag) established knowledge and possession; packaging into 403 small packets supported inference of trafficking; therefore prosecution proved prima facie case and beyond reasonable doubt as to Tertuduh Pertama for trafficking and possession, while Tertuduh Kedua lacked nexus to the purple bag and was acquitted of trafficking but…

DG-83D-990-12/2022 (Mahkamah Majistret)

Although chemical analysis established the seized items were methamphetamine in quantities exceeding statutory thresholds, the prosecution failed to prove the second essential element—control/possession and knowledge—because material inconsistencies and omissions in the police evidence (notably SP2) regarding how the items were found and how the caution/statements were recorded, together with the presence of other persons and the open accessible location, created reasonable doubt; therefore no prima facie case existed and the accused was acquitted and discharged without being called to defend…

PA-45A-68-12/2019 (Mahkamah Tinggi)

Prosecution proved identity and weight of substances by chemical report but failed to exclude reasonable possibility that others (notably Tan Lee Keong) had access to the unlocked room and could have had custody or knowledge of the drugs; the prosecution's failure to call that material witness created a gap such that no prima facie case of possession or trafficking was made out, therefore the accused must be acquitted.

Case number

AA-83-1295-11/2020 (Mahkamah Majistret)

Prosecution failed to establish a prima facie case under s44(1A)(a) because statutory procedure in s45C(5) for deciding blood versus urine was not complied with and material gaps in the chain of custody, labelling and handling of blood specimens undermined the reliability of the chemical report; prosecution also failed to prove that detected drugs caused inability to control the vehicle. Benefit of doubt given to accused.
