This document summarizes a discussion on constitutional law and human rights in Malaysia. It discusses how certain fundamental rights like the right to be informed of arrest grounds and the right to be produced before a magistrate have sometimes been denied to detainees due to legal provisions that override these rights or imperfect law implementation. It then explains the powers granted under Article 149 of the Malaysian constitution to pass laws that can limit fundamental rights in order to combat threats like subversion, even without a state of emergency. Key cases related to judicial review of such laws and the Internal Security Act are analyzed.
