The Electoral Districts Boundaries Commission (EDBC) was established in 1975 under an amendment to the Constitution Act 1934 (SA) to carry out periodic redistributions of the electoral boundaries of the State’s House of Assembly.
The powers and duties of the EDBC are provided in Part 5 of the Constitution Act 1934 (SA).
The EDBC has perpetual succession and the powers and functions of a Royal Commission. The EDBC comprises the most senior puisne Judge of the Supreme Court (The Chair), the Electoral Commissioner and the Surveyor-General.
Redistributions are made on the basis that the number of electors within each of the 47 electoral districts must not vary from the electoral quota by more than 10 per cent.
The EDBC is required to commence its proceedings within 24 months after each polling day for a State general election, or as soon as practicable after there is an alteration to the numbers of members of the House of Assembly.
The EDBC is required to proceed with all due diligence to complete its proceedings. Its order is published in the Government Gazette. There is a limited right of appeal against that order.
