SZDPO & Ors v MIMIA & Anor

The applicants, SZDPO and others, sought judicial review of decisions made by the Minister for Immigration and Multicultural and Indigenous Affairs (MIMIA) and the second respondent, the Refugee Review Tribunal. The dispute concerned the lawfulness of the Minister's decision to refuse to revoke a deportation order made against the applicants, who were non-citizens. The matter came before the High Court of Australia.

The central legal issue before the High Court was whether the Minister's decision not to revoke the deportation order was affected by an error of law. Specifically, the applicants contended that the Minister failed to consider relevant considerations and took into account irrelevant considerations when making that decision. This involved an examination of the scope of the Minister's power under s 48B of the *Migration Act 1958* (Cth) and the principles of administrative law concerning the exercise of such powers.

Gummow and Heydon JJ held that the Minister's decision was vitiated by an error of law. Their Honours found that the Minister had failed to give proper, rational consideration to the applicants' claims for protection, which were relevant considerations under s 48B. The Minister's reasons for refusing to revoke the deportation order were found to be based on an erroneous understanding of the applicants' circumstances and the relevant legal framework. The Court applied the principles established in cases such as *Minister for Immigration and Ethnic Affairs v Teoh* and *Minister for Immigration and Multicultural Affairs v Eshetu*, which emphasise the importance of considering all relevant factors and avoiding irrelevant ones in administrative decision-making.

The High Court ordered that the appeal be allowed, the orders of the Federal Court be set aside, and that the matter be remitted to the Federal Court for further consideration.
