Amazi bin Hawasi v Public Prosecutor: Constitutionality of s 33A(5)(a) of Misuse of Drugs Act

In Amazi bin Hawasi v Public Prosecutor, the High Court of Singapore addressed the constitutionality of section 33A(5)(a) of the Misuse of Drugs Act. The Petitioner, Amazi bin Hawasi, was charged with drug consumption and possession.
