DQU16 & Ors v Minister for Home Affairs and Anor

The applicants, DQU16 and others, sought judicial review of decisions made by the Minister for Home Affairs and the second respondent, concerning their immigration status. The core of the dispute revolved around the lawfulness of the Minister's decision to refuse to revoke a decision that the applicants were not owed protection under the *Migration Act 1958* (Cth). The matter was heard by the High Court of Australia.

The High Court was required to determine whether the Minister's decision to refuse to revoke the original protection decision was vitiated by an error of law. Specifically, the Court considered whether the Minister, in exercising the power under s 48B of the *Migration Act*, failed to consider relevant considerations or took into account irrelevant considerations, thereby rendering the decision legally invalid. The applicants contended that the Minister's assessment of their claims for protection was flawed.

The Court's reasoning focused on the scope of the Minister's discretion under s 48B and the nature of the considerations that must be taken into account when deciding whether to revoke a protection decision. Their Honours held that the Minister's power to revoke a protection decision is discretionary and requires the Minister to consider whether the applicant has established a claim for protection. The Court found that the Minister had properly considered the relevant criteria and had not made an error of law in refusing to revoke the original decision. The applications for judicial review were dismissed.
