Re Refugee Review Tribunal; Ex parte Aala

The High Court of Australia considered an application for prerogative relief by a prosecutor against the Refugee Review Tribunal. The prosecutor sought to challenge a decision of the Tribunal that had refused his application for a protection visa. The central issue arose from an erroneous statement made by the Tribunal at the commencement of the hearing, indicating that it had reviewed certain relevant materials which, in fact, it had not. This statement, the prosecutor contended, led him to believe the Tribunal was fully informed, impacting his presentation of evidence concerning his credibility.

The legal questions before the Court were whether the Tribunal's failure to afford the prosecutor procedural fairness, by making an erroneous statement about its review of evidence and subsequently denying him an opportunity to be heard on matters affecting his credibility, warranted the grant of constitutional writs. Specifically, the Court had to determine the nature of the writ of prohibition, its availability for breaches of procedural fairness, whether it was available as of right or at the Court's discretion, and whether the application should be rejected due to delay. The Court also considered the construction of section 75(v) of the Constitution regarding the meaning of words at the time of its commencement.

The Court reasoned that the Tribunal's erroneous statement, which led the prosecutor to believe it had considered all relevant evidence, constituted a denial of procedural fairness. The prosecutor was not afforded a proper opportunity to address the Tribunal on matters that were critical to its assessment of his credibility, particularly concerning the potential disclosure of information by his friend, Ali Tehrani. The Court affirmed that the writ of prohibition is a constitutional writ available as of right to prevent a superior court or tribunal from exceeding its jurisdiction, and that a failure to accord procedural fairness can amount to an excess of jurisdiction. The Court also found that the prosecutor's application was not barred by delay.

The Court made orders absolute for a writ of prohibition prohibiting the Tribunal from taking action on its decision of 3 April 1998. It also ordered that time be extended and a writ of certiorari issue to quash the Tribunal's decision. Furthermore, a writ of mandamus was ordered, requiring the Tribunal to consider and determine the prosecutor's application according to law. The second respondent was ordered to pay the prosecutor's costs.
