 The Conference's role in amending the Constitution was first set out by the Constitution (Amendment) Act 1971, one of the first pieces of legislation passed by Parliament after the catastrophic May 13 Incident, which saw at least 200 deaths after racial rioting in the federal capital of Kuala Lumpur.The Act named Article 152, 153, and 181, and also Part III of the Constitution as specially protected; any public questioning of these provisions could now be criminalised by Parliament (this was done separately at the same time in amendments to the Sedition Act).The provisions in question covered the social contract (not to be confused with the philosophy of a social contract between the government and the governed), a "quid pro quo" agreement between the Bumiputra and the non-Bumiputra.
