Re Refugee Review Tribunal; Ex parte H

This matter concerned an application for writs of prohibition and certiorari, brought by H, against the Refugee Review Tribunal. H sought to challenge the Tribunal's affirmation of a decision to refuse applications for protection visas, where H's credibility was a central issue. The proceedings before the High Court of Australia were initiated to determine whether the Tribunal's conduct during the hearing gave rise to a reasonable apprehension of bias.

The primary legal issue before the High Court was whether the Tribunal's conduct, specifically its constant interruptions and challenges to H's evidence, could lead a fair-minded lay person to apprehend bias. This required the Court to consider the appropriate modification of the test for apprehended bias when applied in the context of administrative proceedings, as distinct from judicial proceedings. Additionally, the Court considered whether relief under s 75(v) of the Constitution should be refused on discretionary grounds.

The Court reasoned that while vigorous testing of evidence is permissible in administrative hearings, the nature and extent of the Tribunal's interruptions and challenges in this instance went beyond mere testing. The Court applied the principle that a tribunal must not only be impartial but must also appear to be impartial. It concluded that the conduct of the Tribunal created a real possibility that a fair-minded lay observer would apprehend bias. Consequently, the Court made orders absolute for a writ of prohibition prohibiting the respondents from taking action on the Tribunal's decision of 16 November 1999, and a writ of certiorari to quash that decision. Further, a writ of mandamus was ordered requiring the Tribunal to consider and determine H's application according to law, with the respondents ordered to pay H's costs.
