WADT, Ex parte - Re RRT & Anor

This matter concerned an application by WADT for leave to appeal against a decision of the Full Court of the Federal Court of Australia. The application was made to Heydon J, sitting in chambers. The precise nature of the dispute before the Full Court and the identity of the respondents (RRT and Anor) are not detailed in the provided text.

The central legal issue before Heydon J was whether the applicant, WADT, had established sufficient grounds to warrant granting leave to appeal to the High Court. This required an assessment of whether the case involved a question of law that was of general public importance, or whether it was otherwise in the interests of the administration of justice that the High Court should grant leave.

Heydon J considered the principles governing the grant of special leave to appeal to the High Court, which include the requirement for the case to raise a significant question of law or public interest. His Honour's reasoning would have involved an analysis of the arguments presented by WADT in support of its application, and a determination of whether those arguments met the high threshold for granting leave. The provided text does not detail the specific arguments or the outcome of this assessment.
