Theunissen v Government of Commonwealth of Australia & Anor

The applicant, Mr. Theunissen, sought judicial review of a decision made by the Government of the Commonwealth of Australia and a second respondent. The proceedings were heard by Hayne J in chambers.

The central legal issue before the Court was whether the decision of the respondents was amenable to judicial review. Specifically, the Court was required to determine if the decision involved the exercise of a statutory power, a prerequisite for judicial review under the relevant administrative law framework.

Hayne J reasoned that the nature of the decision was critical. His Honour considered whether the decision was one that was made pursuant to a statute, thereby attracting the jurisdiction of the Court. The Court's analysis focused on the source and character of the power exercised by the respondents in reaching their determination.

The application for judicial review was dismissed.
