Amann & Ors, Ex parte - Re The Hon A Emmett

This matter came before Gaudron J in chambers, concerning an application by Amann & Ors for an order nisi for prohibition directed to the Honourable A Emmett, a judge of the Federal Court of Australia. The applicants sought to prohibit the respondent judge from continuing with proceedings in the Federal Court, specifically concerning the determination of certain questions of law in a proceeding instituted by the Commissioner of Taxation.

The central legal issue before Gaudron J was whether the respondent judge had erred in law by determining certain questions of law in the absence of the applicant, who was a party to the underlying Federal Court proceedings. The applicants contended that the judge lacked the power to determine these questions without their participation, arguing that such a determination was premature and potentially prejudicial to their rights.

Gaudron J considered the nature of the application for prohibition and the circumstances under which it could be granted. Her Honour noted that prohibition lies to prevent a court from acting in excess of its jurisdiction or from failing to exercise its jurisdiction. In this instance, the applicants argued that the respondent judge had acted in excess of jurisdiction by making a determination that was not properly before the court, given their absence. However, Gaudron J found that the judge had acted within the scope of the powers conferred by the *Federal Court of Australia Act 1976* (Cth) and the *Income Tax Assessment Act 1936* (Cth) in determining the questions of law. Her Honour concluded that the judge was entitled to proceed with the determination of those questions, even in the absence of the applicants, as the questions were properly raised and the judge had jurisdiction to hear and determine them.

The application for an order nisi for prohibition was therefore dismissed.
