Public Prosecutor v Chum Tat Suan: Sentencing under Misuse of Drugs Act after s 33B Amendment

Chum Tat Suan was convicted under s 7 of the Misuse of Drugs Act for importing diamorphine. Following amendments to the Act, the court considered whether to impose life imprisonment instead of the death penalty, given Chum's role as a courier and the Public Prosecutor's certification of his substantive assistance to the Central Narcotics Bureau. The High Court ultimately exercised its discretion to impose a sentence of life imprisonment, taking into account the circumstances of the case and the legislative intent behind the amendments.
