AWI16 v Minister for Immigration, Citizenship and Multicultural Affairs & Ors

The applicant, AWI16, sought judicial review of a decision by the Minister for Immigration, Citizenship and Multicultural Affairs to refuse to grant a protection visa. The dispute concerned the lawfulness of the Minister's decision, which was made under s 48B of the *Migration Act 1958* (Cth). The matter came before Gageler J of the High Court of Australia.

The central legal issue before the Court was whether the Minister's decision to refuse to grant a protection visa was vitiated by an error of law, specifically concerning the proper construction and application of s 48B of the *Migration Act*. This provision requires the Minister to consider whether it would be contrary to Australia's non-refoulement obligations under international law to remove a non-citizen to a country. The Court was asked to determine the scope of the Minister's duty to consider such matters and the standard of review applicable to the Minister's assessment.

Gageler J reasoned that s 48B imposes a mandatory consideration on the Minister. His Honour held that the Minister's duty under s 48B is to undertake a substantive assessment of whether removal would breach Australia's non-refoulement obligations, rather than merely a formal consideration. The Minister must engage with the evidence and arguments presented by the applicant regarding potential harm in the country of return. The Court applied the principle that where a statute imposes a mandatory duty to consider a matter, a failure to do so constitutes an error of law.

The Court found that the Minister's decision had failed to undertake the required substantive assessment, thereby committing an error of law. Consequently, Gageler J ordered that the application for judicial review be granted, and the Minister's decision be set aside. The matter was remitted to the Minister for reconsideration according to law.
