(December 2016) (Learn how and when to remove this template message) </Td> </Tr> <P> The Interim Constitution provided for a Parliament made up of two houses: a 400 - member National Assembly, directly elected by party - list proportional representation, and a ninety - member senate, in which each of the nine provinces was represented by ten senators, elected by the provincial legislature . The Constitutional Assembly consisted of both houses sitting together, and was responsible for drawing up a final constitution within two years . The adoption of a new constitutional text required a two - thirds supermajority in the Constitutional Assembly, as well as the support of two - thirds of senators on matters relating to provincial government . If a two - thirds majority could not be obtained, a constitutional text could be adopted by a simple majority and then put to a national referendum in which sixty per cent support would be required for it to pass . </P> <P> The Interim Constitution contained 34 constitutional principles with which the new constitution was required to comply . These included multi-party democracy with regular elections and universal adult suffrage, supremacy of the constitution over all other law, a quasi-federal system in place of centralised government, non-racism and non-sexism, the protection of "all universally accepted fundamental rights, freedoms and civil liberties," equality before the law, the separation of powers with an impartial judiciary, provincial and local levels of government with democratic representation, and protection of the diversity of languages and cultures . The Bill of Rights, now in Chapter Two of the Constitution of South Africa, was largely written by Kader Asmal and Albie Sachs . The new constitutional text was to be tested against these principles by the newly established Constitutional Court . If the text complied with the principles, it would become the new constitution; if it did not, it would be referred back to the Constitutional Assembly . </P> <P> The Constitutional Assembly engaged in a massive public participation programme to solicit views and suggestions from the public . As the deadline for the adoption of a constitutional text approached, however, many issues were hashed out in private meetings between the parties' representatives . On 8 May 1996, a new text was adopted with the support of 86 per cent of the members of the assembly, but in the First Certification judgment, delivered on 6 September 1996, the Constitutional Court refused to certify this text . The Constitutional Court identified a number of provisions that did not comply with the constitutional principles . Areas of non-compliance included failures to protect the right of employees to engage in collective bargaining; to provide for the constitutional review of ordinary statutes; to entrench fundamental rights, freedoms and civil liberties and to sufficiently safeguard the independence of the Public Protector and Auditor - General as well as other areas of non-compliance in relation to local government responsibilities and powers . </P>
