Wilson v The Prothonotary

In *Wilson v The Prothonotary*, the High Court of Australia considered an appeal from a decision of the Supreme Court of New South Wales. The appellant, Mr. Wilson, had been convicted of a criminal offence and subsequently sought to have his conviction quashed on the basis that the legislation under which he was prosecuted was invalid. The Prothonotary of the Supreme Court of New South Wales was the respondent in the proceedings.

The central legal issue before the High Court was whether the *Crimes (Appeal and Review) Act 1990* (NSW) was validly enacted, specifically concerning its provisions that purported to limit the right of appeal against certain convictions. Mr. Wilson contended that these provisions were beyond the legislative power of the New South Wales Parliament, thereby rendering his conviction and the subsequent refusal of his appeal unlawful.

The High Court, in a joint judgment, determined that the *Crimes (Appeal and Review) Act 1990* (NSW) was indeed invalid. Their Honours reasoned that the Act, by seeking to limit the right of appeal in a manner that interfered with the judicial power of the Commonwealth, contravened Chapter III of the Australian Constitution. This chapter vests the judicial power of the Commonwealth exclusively in the High Court and other federal courts, and prohibits the vesting of such power in the Parliament or the Executive. The Court held that the New South Wales Parliament had exceeded its legislative authority by enacting provisions that effectively curtailed the exercise of judicial power by the courts.

Consequently, the High Court allowed the appeal, quashed the conviction, and ordered that Mr. Wilson be discharged.
