Mirvac Homes (NSW) Pty Limited v Airservices Australia (No 1)

The case of Mirvac Homes (NSW) Pty Limited v Airservices Australia (No 1) involved a dispute where Mirvac Homes (NSW) Pty Limited sought to challenge an administrative decision made by Airservices Australia. The matter was brought to the Court under the Administrative Decisions (Judicial Review) Act 1977 (ADJR Act) and potentially under section 39B(1A) of the Judiciary Act. The primary focus of the case was on the standing of the applicants and the jurisdiction of the Court to hear and determine the application.

The legal issues central to the case revolved around whether the applicants had standing as 'persons aggrieved' by an administrative decision made by the respondent under an enactment within the meaning of the ADJR Act. Additionally, the Court needed to determine if it had jurisdiction to hear the application even if the ADJR Act was not properly invoked, but instead, the applicants had invoked the jurisdiction under section 39B(1A) of the Judiciary Act.

The Court deliberated on the jurisdictional challenge raised by Airservices Australia and concluded that the matter could proceed if the applicants were indeed 'persons aggrieved' by the administrative decision. The Court also noted that if the applicants had invoked the jurisdiction under section 39B(1A) of the Judiciary Act, it would still have jurisdiction to hear the matter. The Court decided to stand over further consideration of the respondent's notice of objection to competency to allow Airservices Australia to reconsider its position in light of the Court's reasoning.

The Court made orders to stand over the consideration of the notice of objection to competency and to reserve all questions of costs associated with the notice. This decision provided clarity on the jurisdiction of the Court and directed the parties on the next steps in the proceedings.
