XYZ v The Commonwealth

XYZ (the applicant) sought judicial review of a decision made by the Commonwealth (the respondent) to refuse to grant a visa. The applicant, who had a history of criminal convictions, argued that the decision was unlawful on several grounds, including that it was unreasonable and that the decision-maker failed to consider relevant factors. The matter came before Hayne J of the High Court of Australia.

The central legal issue before the Court was whether the decision to refuse the visa was vitiated by unreasonableness, and whether the decision-maker had adequately considered all relevant factors as required by the *Migration Act 1958* (Cth) and associated regulations. Specifically, the Court had to determine if the decision-maker's assessment of the applicant's character and the risk posed to the Australian community was so unreasonable that no reasonable decision-maker could have reached it.

Hayne J applied the principles of administrative law concerning the assessment of reasonableness and the proper consideration of relevant factors. His Honour reviewed the evidence before the decision-maker, including the applicant's criminal record and submissions made on his behalf. The Court considered the threshold for establishing unreasonableness, noting that it is a high one. His Honour found that the decision-maker had properly weighed the competing considerations, including the applicant's past conduct and the potential impact on the community, and had not failed to consider any relevant factors. The decision was found to be within the range of responses available to a reasonable decision-maker.

The application for judicial review was dismissed.
