HFM043 v The Republic of Nauru

The High Court of Australia considered an application for special leave to appeal in *HFM043 v The Republic of Nauru*. The applicant, HFM043, sought to challenge a decision of the Full Federal Court concerning the detention of asylum seekers in Nauru. The core of the dispute revolved around the lawfulness of the applicant's detention and the extent of the Republic of Nauru's obligations under international law.

The central legal issue before the High Court was whether the Full Federal Court had erred in its interpretation and application of the *Migration Act 1958* (Cth) and relevant principles of international law, particularly concerning the detention of non-citizens offshore. Specifically, the court was asked to consider whether the detention regime in Nauru, as implemented by the Republic of Nauru, was compatible with Australia's non-refoulement obligations and whether the Australian government retained sufficient control over the detention arrangements to engage Australian law.

The High Court, in refusing special leave, did not provide detailed reasons for its decision. However, the refusal indicates that the court found no arguable error of law in the Full Federal Court's judgment that would warrant a grant of special leave. The Full Federal Court had previously held that the detention of HFM043 was lawful under Nauruan law and that Australia's obligations under international law did not extend to preventing such detention in the circumstances. The High Court's refusal to grant special leave meant that the Full Federal Court's decision stood.
