Minister for Immigration and Multicultural Affairs v Thiyagarajah

The Minister for Immigration and Multicultural Affairs appealed to the High Court of Australia against a decision of the Full Court of the Federal Court of Australia. The dispute concerned the Federal Court's power to review a decision of the Refugee Review Tribunal (RRT) to refuse a protection visa to the respondent, Mr Thiyagarajah, a citizen of Sri Lanka. The Full Court had allowed Mr Thiyagarajah's appeal from a decision of Emmett J, which had affirmed the RRT's refusal.

The primary legal issue before the High Court was whether the Full Court of the Federal Court had the power, under section 481 of the Migration Act 1958 (Cth), to refer the matter back to the RRT for further consideration, particularly in light of circumstances that may have changed after the RRT's original decision. This involved determining the scope of the Federal Court's appellate jurisdiction and its ability to make orders beyond simply affirming or setting aside the RRT's decision, especially when new factual circumstances arose.

The High Court allowed the Minister's appeal. It reasoned that the Full Court's power under section 28(1)(b) of the Federal Court of Australia Act 1976 (Cth) was not unfettered and was confined by the subject matter of the proceedings. The Court held that the Full Court should have made the orders that could and should have been made at first instance. In this context, the Court found that the RRT had made no error of law in its decision. The Court also noted that the Migration Act itself limited an applicant's ability to seek a second application for a protection visa, and that the RRT did not have the power to reconsider its own decisions based on later changed circumstances.

Consequently, the High Court set aside the orders of the Full Court of the Federal Court and ordered that the appeal to that Court be allowed, with the original application for review being dismissed. The Minister was ordered to pay the reasonable costs of the respondent in the High Court.
