SZDUN v MIMIA

The applicants, SZDUN and others, sought judicial review of a decision made by the Minister for Immigration and Multicultural and Indigenous Affairs (MIMIA). The applicants were asylum seekers who had arrived in Australia by boat and were detained. They challenged the lawfulness of their detention and the Minister's decision to refuse to grant them a protection visa. The case was heard by Gummow and Heydon JJ of the High Court of Australia.

The primary legal issues before the High Court were whether the detention of the applicants was lawful under the *Migration Act 1958* (Cth) and whether the Minister's decision to refuse their protection visa applications was affected by an error of law. Specifically, the applicants argued that their continued detention was arbitrary and therefore unlawful, and that the Minister had failed to properly consider relevant information when assessing their claims for protection.

The High Court considered the provisions of the *Migration Act* relating to the mandatory detention of non-citizens who arrive in Australia without a visa. Their Honours affirmed the principle that detention under the Act is not punitive but is a measure for administrative purposes, aimed at facilitating the processing of immigration claims and ensuring compliance with immigration laws. The Court found that the detention of the applicants was authorised by the *Migration Act* and was not arbitrary, as it was for a purpose contemplated by the legislation and was subject to review. Furthermore, the Court examined the Minister's decision-making process and concluded that there was no error of law in the assessment of the applicants' protection claims.

The High Court dismissed the application for judicial review.
