Parliament finally reconvened again in 1971. Although the NEP was passed without its approval, Parliament's consent was required to amend the Constitution. The government-tabled Constitution (Amendment) Act 1971, in conjunction with some amendments to the Sedition Act, limited freedom of speech on "sensitive issues" such as the national language, Malay special rights, the Malay rulers, and the provisions for citizenship. These restrictions also applied to Members of Parliament, over-ruling their previous Parliamentary immunity. The amendments also clarified Article 152's meaning, and included the "natives of any of the States of Sabah and Sarawak" under Article 153, extending the formerly Malay-only rights to all Bumiputra. In addition, the Yang di-Pertuan Agong (King) could now direct any university or college to implement a proportion-based quota system favouring the Bumiputra. All higher educational institutions immediately enacted quota systems on the orders of the Education Ministry; some later questioned the move's constitutionality on the grounds that the King himself had not issued any directive.
