Commonwealth v Blunden

The Commonwealth of Australia sought special leave to appeal from a decision of the Full Federal Court concerning the interpretation of section 160 of the *Migration Act 1958* (Cth). The primary dispute involved the appellant, Mr. Blunden, a non-citizen, and the respondent, the Commonwealth, regarding the validity of a decision to refuse to grant him a protection visa. The Full Federal Court had found that the delegate's decision was invalid.

The central legal issue before the High Court was whether the delegate, in considering Mr. Blunden's application for a protection visa, had failed to take into account a relevant consideration, specifically the fact that Mr. Blunden had been convicted of a serious criminal offence. This failure, if established, would render the delegate's decision invalid. The High Court was required to determine the proper interpretation and application of section 160 of the *Migration Act*, which deals with the invalidity of decisions made in contravention of the Act.

The High Court, comprising Gleeson CJ and Hayne J, granted special leave to appeal and allowed the appeal. Their Honours reasoned that the delegate's decision-making process, as evidenced by the delegate's reasons, did not demonstrate a failure to consider the criminal conviction. While the conviction was not the primary focus of the delegate's assessment of Mr. Blunden's claims for protection, it was nevertheless a matter that had been before the delegate and was implicitly considered within the broader assessment of the applicant's circumstances. The Court held that the Full Federal Court had erred in concluding that the delegate had failed to take into account a relevant consideration, thereby invalidating the decision. The appeal was allowed, and the orders of the Full Federal Court were set aside.
