WABG v MIMIA

The High Court of Australia heard an appeal concerning the interpretation of the *Migration Act 1958* (Cth) and its application to a non-citizen, WABG, who had been detained under s 189 of the Act. The Minister for Immigration and Multicultural and Indigenous Affairs (MIMIA) was the respondent. The central dispute revolved around whether WABG was entitled to be released from immigration detention pending the determination of his refugee status.

The primary legal issue before the High Court was whether the Minister had a duty to release WABG from detention, or to make arrangements for his release, in circumstances where his detention was not for the purpose of removing him from Australia, but rather for the purpose of processing his refugee claim. This involved an examination of the scope of the Minister's powers and obligations under the *Migration Act*, particularly in relation to the detention of non-citizens who have not been immigration cleared.

Gummow and Hayne JJ held that the *Migration Act* contemplates that a non-citizen who is not immigration cleared may be detained under s 189. They reasoned that the Act does not impose a positive obligation on the Minister to release such a person from detention simply because their refugee claim is being processed. The Court found that the power to detain under s 189 is a power to detain for the purpose of preventing the non-citizen from entering or remaining in the community while their immigration status is resolved, and that this purpose is not exhausted by the mere commencement of a refugee claim assessment. The Court affirmed that detention under s 189 is mandatory for non-citizens who are not immigration cleared, and that release from such detention is not an automatic consequence of making a refugee claim.

The High Court dismissed the appeal, upholding the decision of the Full Federal Court.
