[1] 8 of the referendums, including 5 on the sale of alcohol, did not involve any proposed amendment to the Constitution.
Councils may also conduct polls which are optional to vote in and may be limited to certain voters on a proposal to gain community opinion on building infrastructure or other matters, the result of these polls (like a plebiscite) is non-binding on the Council.
In 1929 the parliament passed an amendment to the Constitution Act which inserted section 7A, requiring a referendum before the Legislative Council could be abolished.
[5] In 1930 Labor MLCs put forward two bills, one to repeal section 7A, the other to abolish the Council.
The validity of section 7A and the inability to repeal the section without a referendum were upheld by the Supreme Court on 23 December 1930,[6] a majority of the High Court on 16 March 1931,[7] and the Judicial Committee of the Privy Council on 31 May 1932.
