Sunday Observance Act (Repeal) Act 1997 (TAS)

In the matter of the Sunday Observance Act (Repeal) Act 1997, the Tasmanian Parliament sought to repeal the Sunday Observance Act 1968, which regulated activities on Sundays. The decision was brought before the High Court of Australia to determine the constitutionality of the repeal. The central legal issue was whether the Tasmanian Parliament had the authority to pass a law repealing the Sunday Observance Act 1968, given that the original Act was passed under the federal government's s 51(xxxviii) power, which allows the Commonwealth to make laws with respect to "religion".

The High Court held that the repeal of the Sunday Observance Act 1968 was valid and did not infringe upon the Commonwealth's legislative powers. The Court reasoned that the repeal was a valid exercise of the Tasmanian Parliament's power under s 109 of the Constitution, which allows a state law to operate notwithstanding a contrary provision in a federal law, provided the state law is not inconsistent with the federal law. The Court found that the repeal did not contravene any federal law and did not impose any religious observance or prohibition inconsistent with the federal law. The Tasmanian Parliament's action was deemed within its legislative competence.

The High Court upheld the validity of the Sunday Observance Act (Repeal) Act 1997, confirming the Tasmanian Parliament's power to repeal the Sunday Observance Act 1968. The decision affirmed that the repeal did not conflict with the Commonwealth's legislative powers concerning religion. The Court's ruling allowed the repeal to proceed, thereby permitting activities previously restricted on Sundays to be legally undertaken.
