Day v Australian Electoral Officer for the State of South Australia & Anor; Madden & Ors v Australian Electoral Officer for the State of Tasmania & Ors

The High Court of Australia considered challenges brought by Mr Day and by Mr Madden and others concerning the validity of electoral rolls prepared for federal elections. Mr Day's challenge related to the South Australian electoral roll, while Mr Madden's challenge concerned the Tasmanian electoral roll. Both challenges were brought under section 476 of the *Commonwealth Electoral Act 1918* (Cth) (the Act), which provides for the judicial review of decisions made under the Act.

The central legal issue before the Court was whether the electoral rolls in question were validly prepared and maintained in accordance with the requirements of the Act, specifically concerning the inclusion and exclusion of electors. The applicants contended that the rolls were defective due to alleged failures to properly remove individuals who were no longer entitled to be enrolled, thereby potentially affecting the integrity of the electoral process.

The Court, led by French CJ, examined the provisions of the Act relating to the preparation and maintenance of electoral rolls, including the obligations of electoral officers and the rights of electors. The reasoning focused on the interpretation of sections such as 101, 104, and 105 of the Act, which deal with the removal of names from the roll. The Court affirmed the principle that electoral rolls must be accurate and up-to-date, but also considered the practicalities of roll maintenance and the statutory framework governing these processes. The Court ultimately found that the electoral rolls in question were validly prepared and maintained according to the Act, and therefore dismissed the applications.
