What was Yong Vui Kong's legal case on the Misuse of Drugs Act?

Yong Vui Kong v Public Prosecutor was a landmark 2010 case where the Singapore Court of Appeal upheld the mandatory death penalty for certain drug trafficking offences. The court ruled that the mandatory death penalty did not violate constitutional protections of life, personal liberty, or equality before the law. Later, following legislative changes to the Misuse of Drugs Act in 2012 and 2013, Yong's sentence was successfully commuted to life imprisonment and caning.

What we know

• Yong Vui Kong was sentenced to death in Singapore for trafficking more than 15 grams of heroin. [2]
• The Court of Appeal ruled in 2010 that the mandatory death penalty under the Misuse of Drugs Act does not violate Articles 9(1) and 12(1) of the Constitution of Singapore. [3]
• The court held that the 15-gram threshold in the Misuse of Drugs Act bears a rational relation to the social object of preventing drug addiction. [3]
• In 2013, Yong's death sentence was commuted to life imprisonment and caning following amendments allowing alternative sentences for couriers or those with mental illnesses. [2, 3]

Still open

• The sources do not specify whether customary international law or foreign constitutional precedents should heavily influence domestic interpretations of Singapore's fundamental liberties, though the court rejected incorporating them into Article 9(1).
