Flint v Webb

This case concerned an appeal to the High Court of Australia from a Court of Petty Sessions of Victoria. The appellant, Arthur Loftus Flint, an officer in the Postmaster-General's Department, had been ordered to pay income tax to the State of Victoria. Flint contended that as a Commonwealth public servant, he was not subject to State taxation for his salary.

The legal issues before the High Court included whether the Court of Petty Sessions was exercising federal jurisdiction, the validity of section 39 of the Judiciary Act 1903, and, fundamentally, whether a State could tax the salary of a Commonwealth officer, which involved interpreting the constitutional division of powers between the Commonwealth and the States. Following the High Court's decision allowing the appeal, an application was made for a certificate under section 74 of the Constitution to appeal to the Privy Council.

The High Court, in considering the application for a certificate, determined that the existence of conflicting decisions between the High Court and the Privy Council, or the inconvenience arising from such a conflict, did not, of itself, constitute a "special reason" for granting a certificate under section 74. The Court noted that such inconvenience could be remedied by the Commonwealth Parliament exercising its legislative powers.

The application for a certificate was refused. The Court held that while the existence of conflicting interpretations of the Constitution between the High Court and the Privy Council was inconvenient, it was not an "intolerable position" that necessitated a certificate. The Court reiterated that the Commonwealth Parliament had the power to resolve such conflicts through legislation, and that the High Court's role as the interpreter of the Constitution in these matters was paramount unless exceptional circumstances warranted a departure.
