 The provisions covered were (respectively) those relating to Malay as the national language, the special privileges and rights of the Malays and other indigenous peoples (Bumiputra, constituting more than half the Malaysian population), the status of the Malay rulers, and the provisions for Malaysian citizenship.These restrictions applied to all Malaysians, including members of parliament, over-ruling their Parliamentary immunity.In addition, Article 159(5), which governed amendments to the Constitution, was also amended to require the provisions of the Constitution relating to the "sensitive issues" mentioned earlier be amended only with the consent of the Conference of Rulers.
