The major changes were an increase in the authority of the government, described as "a vehicle for the sovereignty of the people". It gave the government the power to act without constitutional restraints, with the courts having no rights to question the validity of the laws passed by the assembly.[1][2] All laws passed by the NSA were valid until repealed by the assembly itself. The assembly saw the introduction of socialist principles and a constitutional foundation to the pre-eminent position of Sinhala and Buddhism. Both the judiciary and Civil Service came under political control.[2] The assembly was unicameral and initially consisted of the 151 elected members of its predecessor the House of Representatives, as the Senate had been abolished in 1971. The first amendment to the current constitution was to increase the number of members to 168.
