Members of Parliament possess parliamentary privilege and are permitted to speak on any subject without fear of censure outside Parliament; the only body that can censure an MP is the House Committee of Privileges. Immunity is effective from the moment a member of Parliament is sworn in, and only applies when that member has the floor; it does not apply to statements made outside the House. An exception is made by the Sedition Act passed by Parliament in the wake of the 13 May racial riots in 1969. Under the Act, all public discussion of repealing certain Articles of the Constitution dealing with Bumiputra privileges such as Article 153 is illegal. This prohibition is extended to all members of both houses of Parliament. Members of Parliament are also forbidden from criticising the King and judges.
