WET044 v The Republic of Nauru

The High Court of Australia heard an appeal from a decision of the Federal Court of Australia concerning the detention of a person, identified as WET044, by the Republic of Nauru. The dispute arose from the circumstances surrounding WET044's detention and the legal basis for that detention, which was challenged in Australian courts.

The central legal issue before the High Court was whether the Australian government, through its actions and agreements with Nauru, retained sufficient control or responsibility over WET044's detention to engage Australian legal obligations, particularly concerning the legality of that detention. This involved considering the extent to which Australia's involvement in offshore processing arrangements could render it amenable to judicial review in Australia for actions taken in Nauru.

The High Court considered the nature of the regional processing arrangements and the extent of Australian executive power and responsibility in relation to the detention of asylum seekers in Nauru. The Court analysed the principles of administrative law and international law relevant to offshore detention and the extraterritorial application of Australian law. The judges ultimately determined that the Australian government's involvement did not extend to a level of control that would make it directly responsible for the legality of WET044's detention in Nauru under Australian law.

The High Court allowed the appeal, setting aside the orders of the Federal Court.
