Roszaidi Bin Osman v PUBLIC PROSECUTOR

Majority held that the Second Limb is satisfied because appellant’s MDD and SUD operated synergistically (MDD was the underlying substrate exacerbating SUD) and that the combined disorders substantially impaired the appellant’s mental responsibility (particularly his ability to control his actions and resist drug-seeking) in relation to both his decision to traffic and the specific act of handing the drugs to his wife; accordingly s33B(3)(b) is made out and the death sentence was set aside and substituted with life imprisonment under s33B(1)(b).

  • Diminished responsibility
  • S33b alternative sentencing for drug couriers
  • Major depressive disorder
  • Substance use disorder
  • Synergistic disorders
  • Death penalty mitigation
