AIU16 v Minister for Immigration and Border Protection & Anor

The applicants, AIU16 and AIU17, sought judicial review of decisions made by the Minister for Immigration and Border Protection and the second respondent, the Department of Home Affairs, concerning their applications for protection visas. The core of the dispute revolved around the lawfulness of the respondents' decisions to refuse to grant these visas, which the applicants contended were affected by jurisdictional error. The matter was heard by Gageler and Nettle JJ of the High Court of Australia.

The High Court was required to determine whether the delegate of the Minister had erred in law by failing to consider, or adequately consider, the applicants' claims for protection under the *Migration Act 1958* (Cth) and the *Migration Regulations 1994* (Cth). Specifically, the court examined whether the delegate's assessment of the applicants' fear of persecution was based on an erroneous understanding of the relevant legal principles, particularly concerning the assessment of subjective fear and objective risk. The central legal issue was whether the delegate's findings were so lacking in evidential support or logical coherence as to constitute a jurisdictional error.

Gageler and Nettle JJ reasoned that a failure to consider a claim for protection, or a consideration that is so inadequate as to amount to no consideration at all, constitutes a jurisdictional error. They applied the principles established in cases concerning the assessment of claims for protection visas, emphasizing that the delegate must undertake a genuine assessment of the evidence presented and the claims made by the applicant. The court found that the delegate's decision-making process, as revealed in the reasons provided, demonstrated a misunderstanding of the evidentiary burden and the nature of the assessment required, leading to a conclusion that the delegate had not properly considered the applicants' claims.

The High Court ordered that the applications for judicial review be upheld, quashed the decisions of the Minister and the Department, and remitted the applications for protection visas to the Minister for reconsideration according to law.
