On March 4, 2015, Singapore’s Court of Appeal issued its judgment in Yong Vui Kong v. Public Prosecutor, upholding the punishment of caning imposed on the defendant as constitutional. The decision is significant because it discusses the impact of the prohibition of torture, a peremptory norm of international law, on domestic legislation. The Court of Appeal determined that, even if caning were to be considered a form of torture, the customary international law prohibition on torture did not invalidate its domestic law permitting caning as a form of punishment.
