Ultra vires-Appeal to Privy Council - Application for certificate - The Constitution (63 &64 Vict. c. 12), sec. 51, sub-sec. (xxxix.), secs. 73-77.
In an action in a New South Wales District Court to recover income tax under the Land and Income Tax Act of that State from a federal officer in respect of his salary as such officer, the defendant claimed to be exempt from (N.S.W.)
liability on the ground that the taxation of his income was an interference with the free exercise of the powers of the Commonwealth within the meaning of the rule laid down in D'Emden v. Pedder, 1 C.L.R., 91, and therefore impliedly prohibited by the Constitution. The Judge, following the decision of the Privy Council in Webb v. Outtrim, (1907) A.C., 81, gave judgment for the plaintiffs. The defendant appealed direct to the High Court, adopting the procedure prescribed by the State law for appeals to the Supreme Court.
Held, that the question raised by the defence was a question as to the limits inter se of the constitutional powers of the Commonwealth and a State within the meaning of sec. 74 of the Constitution, that the District Court was therefore exercising federal jurisdiction under sec. 39 of the Judiciary Act 1903, and the appeal was competent by virtue of sub-sec. (2) (a) of that section, as well as by sec. 73 of the Constitution.
Held, further (per Griffith C.J., Barton and O'Connor JJ.), that the High Court was, by the Constitution, the ultimate arbiter upon all such questions, unless it was of opinion that the question at issue in any particular case was one upon which it should submit itself to the guidance of the Privy Council, and was therefore not bound to follow the decision in Webb v. Outtrim, (1907) A.C., 81, but should follow its own considered decision in Deakin v. Webb, C.L.R., 585, in which it had refused to grant a certificate under sec. 74, unless upon a reconsideration of the question for whatever reason it should come to a different conclusion and that, assuming the fact that the Privy Council had given a decision in direct conflict with the High Court on the same point to be a sufficient reason for a reconsideration of the whole matter by the High Court, there was nothing in the reasons of the Judicial Committee to throw any new light on the question involved, either with regard to the necessity for the implication of the rule of implied prohibition laid down in M'Culloch v. Maryland, 4 Wheat., 316, and adopted in D'Emden v. Pedder, 1 C.L.R., 91, or as to the applicability of the rule to the particular question.
The rule in D'Emden v. Pedder, 1 C.L.R., 91, reaffirmed. In construing the Constitution regard must be had to the fact that it is an instrument of government calling into existence a new State with sovereign powers, subject only to the British Crown.
The duty of the High Court in regard to questions under sec. 74 is to be determined upon consideration of the whole purview and history of the Con.
Per Isaacs J. Apart from any consideration of its history, the words of sec. 74 are clear and strong enough to lead to the conclusion that on questions coming within the section the decision of the High Court was final, and, therefore, the Court had a right to decline to follow the decision of the Privy
