WAKK v MIMIA

The applicants, WAKK and MIMIA, brought proceedings before the High Court of Australia concerning the interpretation of certain provisions of the *Migration Act 1958* (Cth) and the *Migration Regulations 1994* (Cth). The dispute centred on the lawfulness of a decision made by the Minister for Immigration and Multicultural and Indigenous Affairs to refuse to grant a protection visa to the first applicant, WAKK, who was a citizen of Afghanistan. MIMIA, the Minister, was the respondent in the proceedings.

The primary legal issue before the High Court was whether the Minister's decision to refuse the protection visa was vitiated by a failure to consider relevant considerations or by the consideration of irrelevant considerations, as required by administrative law principles. Specifically, the court had to determine if the Minister had adequately considered the evidence presented by WAKK regarding the risk of persecution in Afghanistan and whether the Minister had unlawfully relied on information that was not before him at the time of the decision.

In their joint judgment, Hayne and Crennan JJ analysed the scope of the Minister's duty to consider relevant material when making a decision on a protection visa application. Their Honours affirmed that the Minister must consider all material that is relevant to the decision, and conversely, must not have regard to material that is irrelevant. The court examined the specific evidence before the Minister and the reasons provided for the refusal, concluding that the Minister had failed to properly consider crucial aspects of WAKK's claim, thereby breaching the duty to consider relevant considerations. The court found that the Minister had impermissibly relied on information that was not part of the material before him when forming his opinion.

Consequently, the High Court allowed the appeal, quashed the decision of the Minister to refuse the protection visa, and remitted the matter to the Minister for reconsideration according to law.
