Attorney-General for the State of WA and Anor v Marquet P115/2002

The High Court of Australia heard an appeal concerning the Attorney-General for the State of Western Australia and another party (the appellants) against a decision involving Mr. Marquet (the respondent). The dispute centred on the validity of certain provisions of the *Criminal Code Amendment Act 2002* (WA) and their application to the respondent.

The primary legal issue before the Court was whether the impugned provisions of the *Criminal Code Amendment Act 2002* (WA) were invalid by reason of inconsistency with the *Commonwealth Constitution*, specifically section 118, which mandates that full faith and credit shall be given throughout the Commonwealth to the public Acts, records, and judicial proceedings of every State. The Court was required to determine if the Western Australian legislation, in its operation, impaired the ability of other States to give effect to their own laws or judicial decisions.

Gaudron J, in chambers, considered the arguments presented regarding the potential conflict between the Western Australian legislation and the constitutional requirement of full faith and credit. The decision ultimately turned on the interpretation of section 118 and its application to the specific circumstances of the case, focusing on whether the State Act unduly interfered with the recognition and enforcement of laws or judgments from other Australian jurisdictions.
