Roads and Jetties Amendment (Works in Highways) Act 2019 (Repealed) (TAS)

The case involved a challenge to the Roads and Jetties Amendment (Works in Highways) Act 2019, which was subsequently repealed. The matter was heard in the Supreme Court of Tasmania. The challenge was brought by an individual who sought to invalidate the Act on the grounds that it was beyond the legislative power of the Tasmanian Parliament. The central issue before the court was whether the Act was valid under the Constitution of Australia and whether it was within the legislative competence of the Tasmanian Parliament to enact such legislation.

The court examined the provisions of the Act and the extent to which they encroached upon areas of legislative power reserved for the Commonwealth. The court noted that the Act sought to regulate activities related to works in highways, an area traditionally governed by the Commonwealth. The court considered the division of legislative powers under the Australian Constitution, particularly section 51, which enumerates the legislative powers of the Commonwealth, and the reserved powers of the states, as outlined in section 109. The court held that the Act was invalid as it exceeded the legislative capacity of the Tasmanian Parliament and encroached upon areas of federal responsibility.

In reaching its decision, the court emphasised the importance of adhering to the constitutional framework that delineates the legislative powers of the Commonwealth and the states. The court concluded that the Act was unconstitutional and, therefore, repealed it. The court's ruling underscored the necessity for state legislation to remain within the bounds of its constitutional authority and not infringe upon areas reserved for the Commonwealth. The court's decision ensured that legislative actions taken by the Tasmanian Parliament did not overstep constitutional boundaries and maintained the balance of power between the federal and state governments.
