McMillan, An application by

This matter concerned an application by McMillan for leave to appeal to the High Court of Australia. The application arose from a dispute concerning the interpretation and application of the *Migration Act 1958* (Cth) and related regulations, specifically concerning the validity of a decision made by the Minister for Immigration and Multicultural Affairs.

The central legal issue before Heydon J was whether the applicant had demonstrated an arguable case of error in the decision of the primary court, which had previously considered the merits of the migration decision. This involved assessing whether the applicant's proposed grounds of appeal raised a question of law of sufficient importance to warrant the High Court's attention, particularly in the context of administrative law and the review of ministerial discretions.

Heydon J considered the principles governing the grant of special leave to appeal, which require a demonstration of an error of law that is substantial and of general application, or a matter of public importance. His Honour reviewed the applicant's arguments and the relevant legal framework, ultimately concluding that the grounds of appeal did not meet the threshold for special leave. The application was therefore dismissed.
