Keating, An application by

This matter concerned an application by Mr Keating for leave to appeal against a decision of the Full Federal Court. The dispute arose from a taxation assessment issued by the Commissioner of Taxation to Mr Keating, which he sought to have set aside. The application was heard by McHugh J of the High Court of Australia.

The central legal issue before McHugh J was whether the Full Federal Court had erred in its interpretation of section 160AF(1) of the *Income Tax Assessment Act 1936* (Cth) (the Act). Specifically, the court was required to determine whether the Full Federal Court had correctly applied the principles of statutory construction in relation to the Commissioner's discretion under that provision.

McHugh J’s reasoning focused on the proper approach to interpreting taxing legislation and the scope of judicial review of administrative discretions. His Honour considered the established principles of statutory interpretation, emphasizing that the plain meaning of the words in the statute should be given effect. He also examined the circumstances in which a court may interfere with a discretionary power vested in a public official, noting that such interference is generally limited to cases where the discretion has been exercised improperly or for an irrelevant purpose.

McHugh J granted leave to appeal and, upon appeal, allowed Mr Keating's appeal, setting aside the decision of the Full Federal Court.
