Legislation may cease operation through—
- express repeal or revocation
- implied repeal or revocation (for example, a regulation is impliedly revoked when the section of the Act under which it was made is repealed and not replaced with a similar provision)
- expiry pursuant to a provision of the legislation or some other legislation, including in the case of regulations, expiry under the Subordinate Legislation Act 1978
- being superseded (for example, the Companies (Application of Laws) Act 1982 has been supreseded by the Corporations (South Australia) Act 1990).
This website includes the text of Acts and regulations and rules made by the Governor that have ceased operation since 1 January 2003 and information about Acts and regulations and rules made by the Governor that ceased operation between 1 January 1976 and 1 January 2003. (However, for regulations and rules, the information is limited due to a past practice of deleting the information once the revoking regulations or rules had themselves ceased.) The Office of Parliamentary Counsel holds the text of certain of these Acts, regulations and rules and will make it available on this website as resources allow.
For information about Acts and subordinate legislation that ceased operation before 1 January 1976 consult the tables and indexes in Volume 9 South Australian Statutes 1837-1936 and, for Acts, the 1975 Volume of South Australian Statutes.
