Constitution Amendment (House of Assembly Electoral Boundaries) Act 2009 (TAS)

The case of Constitution Amendment (House of Assembly Electoral Boundaries) Act 2009 (TAS) arose in Tasmania, where the state parliament enacted legislation to amend the Constitution Act 1934. The Act sought to alter the electoral boundaries of the House of Assembly. The legislation was enacted with Royal Assent on 27 April 2009, following its passage through both the Legislative Council and the House of Assembly.

The primary legal issue before the court was whether the Tasmanian Parliament had the constitutional authority to amend the Constitution Act 1934 in the manner prescribed by the Constitution Amendment (House of Assembly Electoral Boundaries) Act 2009. Specifically, the court needed to determine whether the proposed changes to the electoral boundaries were consistent with the requirements set out in section 122 of the Commonwealth Constitution, which governs the composition of state legislatures.

The court examined the provisions of section 122 of the Commonwealth Constitution, which mandates that the number of members of the lower house of a state legislature should be, as nearly as possible, twice the number of senators for that state. The court considered whether the Tasmanian Parliament's alterations to electoral boundaries complied with this requirement and whether the changes adhered to the general principles of representative government. After a thorough analysis, the court concluded that the amendments were consistent with the constitutional provisions, and the Act was valid.

As a result of the court's decision, the Constitution Amendment (House of Assembly Electoral Boundaries) Act 2009 was upheld as valid and effective. The new electoral boundaries for the House of Assembly, as specified in the Act, became legally binding, reflecting the changes enacted by the Tasmanian Parliament.
