A children's curfew law is a regulation designed to restrict the presence of children in public places during specific hours. The primary objective of this law is to decrease the likelihood of children becoming involved in criminal activities either as perpetrators or victims. As of now, Malaysia has not implemented any children's curfew law. This article seeks to explore the historical context of children's curfew laws, their effectiveness in the United States, and the feasibility of introducing such legislation in Malaysia, considering Article 9 of the Federal Constitution. The article concludes that a children's curfew law aligns with Article 9 as it aims to safeguard the well-being and safety of children, without indiscriminately restricting children’s right to movement. Additionally, the government, acting as parens patriae, assumes a protective role in caring for children and supporting the parental responsibility of family institutions.
