NANV v MIMIA

The High Court of Australia heard an appeal concerning the interpretation of the *Migration Act 1958* (Cth) in a dispute between NANV and MIMIA. The core of the disagreement revolved around the validity of a decision made by the Minister for Immigration and Multicultural and Indigenous Affairs to refuse to revoke a deportation order made against NANV, a non-citizen. NANV sought judicial review of this decision, arguing it was vitiated by jurisdictional error.

The central legal question before the High Court was whether the Minister, in considering whether to revoke a deportation order under s 501(1) of the *Migration Act*, was bound to consider all the circumstances of the case, including those that arose after the original deportation order was made. NANV contended that the Minister's failure to consider such later-arising circumstances constituted a failure to exercise the power conferred by the section according to its terms, thereby amounting to jurisdictional error.

Gummow and Kirby JJ, in their joint judgment, held that the power to revoke a deportation order under s 501(1) required the Minister to consider all relevant circumstances at the time of the decision to revoke, including those that had arisen since the making of the original order. Their Honours reasoned that the statutory language contemplated a fresh assessment of the situation. The Minister's failure to undertake this comprehensive review meant that the Minister had not exercised the power vested in him by the legislation, leading to a jurisdictional error. Consequently, the appeal was allowed, and the matter was remitted to the Federal Court for further consideration.
