WACB v MIMIA

The High Court of Australia considered an appeal by WACB against a decision of the Full Federal Court concerning the interpretation of the *Migration Act 1958* (Cth). The dispute centred on whether a particular visa cancellation decision was valid. MIMIA (Minister for Immigration and Multicultural and Indigenous Affairs) was the respondent.

The primary legal issue before the High Court was whether the Minister had properly exercised the power to cancel the appellant's visa under s 501(2) of the *Migration Act 1958* (Cth), specifically in relation to the appellant's character. The court also had to determine whether the delegate's decision to cancel the visa was vitiated by a failure to consider relevant considerations or by taking into account irrelevant considerations.

The High Court reasoned that the Minister's power under s 501(2) required a satisfaction that the person did not pass the character test. This satisfaction must be based on information that is relevant to the character test. The court found that the delegate's decision had been influenced by a misunderstanding of the appellant's criminal record and a failure to give sufficient weight to mitigating factors presented by the appellant. Consequently, the delegate's decision was found to be affected by an error of law, as it failed to properly consider relevant material and was based on an erroneous view of the facts.

The High Court allowed the appeal, setting aside the decision of the Full Federal Court and remitting the matter to the Federal Court for determination according to law.
