Article 9 of the Constitution of the Republic of Singapore, specifically Article 9(1), guarantees the right to life and the right to personal liberty. The Court of Appeal has called the right to life the most basic of human rights, but has yet to fully define the term in the Constitution. Contrary to the broad position taken in jurisdictions such as Malaysia and the United States, the High Court of Singapore has said that personal liberty only refers to freedom from unlawful incarceration or detention.
