BD-62D-61-08/2025 (Mahkamah Sesyen)

Accused's unqualified guilty plea and forensic proof of morphine in urine establish the offence under Section 15(1)(a); prior conviction activates enhanced mandatory sentencing under Section 39C(2); whipping is excluded due to accused being over fifty (Section 289(c)); mitigating value of early plea acknowledged but outweighed by extensive prior convictions (18 recorded) and public interest, resulting in an 8‑year custodial sentence from date of arrest and 2 years supervision under Section 38B.

Court convicted the accused on proof of urine tests and prior conviction records, accepted the guilty plea but found the mitigating value outweighed by extensive prior convictions and public interest, applied Section 39C(1) (read with Section 38B) and, because whipping was precluded by age, imposed imprisonment of six years from 15-5-2025 plus two years supervision.

JA-82D-22-05/2024 (Mahkamah Majistret)

The court found the prosecution proved identity and unbroken chain of custody for the urine sample, the testing complied with s31A and the laboratory confirmed Amphetamine and Methamphetamine which are scheduled drugs; the statutory presumption under s37(k) therefore applied and the accused failed to rebut it on the balance of probabilities or to raise a reasonable doubt; accordingly the accused was convicted under s15(1)(a) DDA and sentenced.

Section 39C(1)(b) applied because the accused had two prior convictions under s15(1)(a); the provision mandates imprisonment between five and seven years and whipping up to three strokes, leaving the court only the discretion to fix the term within that range. The guilty plea was considered but outweighed by the seriousness of the offence, repeated offending and public interest; accordingly the court sentenced the accused to 6 years 6 months imprisonment, 3 strokes and 3 years of supervision under s38.

JA-82D-42-08/2021 (Mahkamah Majistret)

Although the prosecution established a prima facie case with an unbroken chain of custody and positive laboratory results for Amphetamine and Methamphetamine under s31A and s37(k), the defence produced credible corroborative evidence (witness testimony of drink tampering and contemporaneous statements) that raised a reasonable doubt and rebutted the statutory presumption; failure of the police to investigate that defence materially prejudiced the accused, therefore the prosecution failed to prove guilt beyond reasonable doubt and the accused is acquitted.

WA-42S-10-10/2022 (Mahkamah Tinggi)

Appellate court found the trial judge erred in fact and law by failing to properly evaluate the accused's defence and corroborating testimony of co-arrestee, and by ignoring material weaknesses in the labelling and chain of custody of urine samples; those infirmities raised a reasonable doubt as to identity of the sample and thus conviction could not be sustained; conviction set aside and accused acquitted and discharged.

Evidence established that the accused's urine sample was labelled, sealed and analyzed showing methamphetamine; discrepancies were immaterial; chain of custody gaps were not fatal given sealing and continuity to chemist; statutory presumption under s.37(k) applied and was not rebutted; charge amended under s.158 CPC to correct place; consequently prosecution proved a prima facie case under s.15(1)(a) DDA 1952 and accused was guilty.

After reviewing the record de novo the High Court found prosecution evidence—including supervised collection, signed labels, photographic and custody records, and GCMS analysis—proved the urine samples came from the accused and contained amphetamine and methamphetamine; defence challenges were untested on the relevant witnesses and amounted to afterthoughts; court records proved prior convictions admissibly via the deputy registrar; therefore conviction was safe under s15(1)(a) DDA 1952 punishable under s39C and the sentence was within lawful range; appellate court affirmed conviction and sen…

The High Court set aside the Sessions Court's discharge and acquitted order and entered a conviction because the prosecution established identity and integrity of urine samples, forensic tests confirmed methamphetamine, statutory presumption under s37(k) applied and was not rebutted on the balance of probabilities, the defence's recall of PW1 indicated acceptance of his evidence and the defence failed to raise a reasonable doubt sufficient to overturn the presumption.

The High Court held the Magistrate did not err in principle and the sentence (RM1000 fine in default 3 months imprisonment and two‑year supervisory order) was not manifestly inadequate or excessive given the respondent was a juvenile, the Laporan Akhlak recommendations, the plea of guilty and the need to balance public interest with rehabilitation; appeal dismissed and sentence affirmed.
