Peck v State of Western Australia

The High Court of Australia considered an appeal by Mr Peck against the State of Western Australia concerning the validity of certain provisions of the *Criminal Code Act Compilation Act 1913* (WA) and the *Criminal Code* (WA) as they applied to him. The dispute arose from Mr Peck's conviction for offences under these provisions, which he contended were invalidly enacted.

The central legal issue before the High Court was whether the Western Australian Parliament had the constitutional power to enact the impugned provisions of the *Criminal Code*. Specifically, the Court had to determine if these provisions, which related to the definition and punishment of certain offences, were within the legislative competence of the State Parliament, or if they encroached upon powers exclusively vested in the Commonwealth Parliament under the Australian Constitution.

The High Court ultimately found that the provisions of the *Criminal Code* in question were validly enacted by the Western Australian Parliament. The Court reasoned that the State Parliament possessed the necessary legislative authority to enact laws for the peace, order, and good government of Western Australia, which included the power to define and punish criminal offences within its jurisdiction. The Court rejected arguments that these provisions were invalid by reason of any purported inconsistency with Commonwealth legislation or the Constitution. The appeal was dismissed.
