Worrall and Civil Aviation Safety Authority

The applicant, Mr Worrall, sought judicial review of a decision made by the Civil Aviation Safety Authority (CASA). The dispute concerned whether the Administrative Appeals Tribunal (AAT) had jurisdiction to hear Mr Worrall's application for review of CASA's decision.

The primary legal issue before the court was whether the AAT possessed jurisdiction to review CASA's decision to refuse to grant Mr Worrall an exemption from certain regulations under the *Civil Aviation Act 1988* (Cth). Specifically, the court had to determine if the decision under review was one that the AAT was empowered to hear and determine, given the nature of the decision and its impact on Mr Worrall's aviation licence.

The court reasoned that the AAT's jurisdiction to review decisions of CASA is conferred by specific provisions of the *Civil Aviation Act 1988* (Cth) and the *Administrative Appeals Tribunal Act 1975* (Cth). It found that the decision in question, which related to an exemption from regulations and did not directly affect the validity or conditions of Mr Worrall's pilot licence, did not fall within the scope of decisions over which the AAT had jurisdiction. The court applied the principle that the AAT's jurisdiction is limited to those matters expressly or by necessary implication conferred upon it by statute.

Consequently, the court found that the AAT did not have jurisdiction to hear Mr Worrall's application for review.
