The principles of the current Constitution of South Australia, also known as the South Australian Constitution, which includes the rules and procedures for the government of the State of South Australia, are set out in the Constitution Act 1934. Its long title is "An Act to provide for the Constitution of the State; and for other purposes".
The Act provides for certain sections to be altered by the process of a Bill proposing a change passing all readings, approval by a majority of members in both houses of parliament prior to being assented to by the Governor. It also specifies those sections of the South Australian Constitution that must not only pass a majority vote in both Houses but must then be put to the people of South Australia at a referendum.
The first Act to set out the South Australian Constitution was the Constitution Act 1856, which was the first Constitution in the Australian colonies to provide universal manhood suffrage.
