Re MIMIA; Ex Parte Ame

The High Court of Australia considered an application for special leave to appeal in *Re MIMIA; Ex Parte Ame*. The applicant, Ame, sought special leave to appeal from a decision of the Full Federal Court of Australia. The dispute concerned the interpretation and application of the *Migration Act 1958* (Cth) and related regulations, specifically in relation to the review of decisions made by the Migration Internal Review Office (MIRO).

The central legal issue before the High Court was whether the Full Federal Court had erred in its interpretation of the jurisdictional error provisions within the *Migration Act*. This involved determining the scope of judicial review available for decisions made by MIRO, particularly concerning the question of whether a failure to provide reasons for a decision constituted a jurisdictional error that could be grounds for setting aside the decision.

The High Court, in refusing special leave, implicitly affirmed the Full Federal Court's reasoning. The Full Federal Court had held that a failure by MIRO to provide reasons for its decision, in circumstances where the governing legislation did not mandate such reasons, did not amount to a jurisdictional error. The court applied established principles of administrative law, distinguishing between errors of law that might render a decision invalid and jurisdictional errors that go to the very power of the decision-maker to make the decision. The court found that MIRO had acted within its statutory powers, and any omission to provide reasons, absent a statutory obligation, did not vitiate the decision.
