Applicant M30 of 2004 v MIMIA & Anor

The applicants, identified as M30 of 2004, sought judicial review of decisions made by the Minister for Immigration and Multicultural and Indigenous Affairs (MIMIA) and the second respondent. The dispute concerned the lawfulness of the Minister's decision to refuse to grant a protection visa to the applicants, who were citizens of Iran. The matter came before the High Court of Australia.

The central legal issue before the High Court was whether the Minister's decision to refuse the protection visa was vitiated by a failure to afford the applicants procedural fairness. Specifically, the applicants contended that the Minister had failed to provide them with adequate notice of adverse information that was to be relied upon in assessing their claims for protection, thereby preventing them from responding to that information.

Gummow and Heydon JJ considered the principles of procedural fairness in the context of administrative decision-making, particularly concerning the assessment of refugee claims. Their Honours affirmed that where an administrative decision-maker proposes to make a decision adverse to a party based on information that has not been disclosed to that party, procedural fairness generally requires that the party be given an opportunity to comment on that information. The Court found that the Minister's delegate had failed to provide the applicants with sufficient particulars of the adverse information concerning their claims, which prevented them from making a meaningful response. Consequently, the delegate's decision was found to be affected by a jurisdictional error.

The High Court made orders quashing the decision of the Minister's delegate to refuse the protection visa. The matter was remitted to the Minister for reconsideration according to law.
