Constitution, no implication of a prohibition against the exercise of that power can arise, nor can a possible abuse of the power narrow its limits.
The Commonwealth of Australia Constitution Act, being passed by the Imperial Parliament for the express purpose of regulating the royal exercise of legislative, executive and judicial power throughout Australia, is by its own inherent force binding on the Crown to the extent of its operation.
The Constitution, as it exists for the time being, dealing expressly with sovereign functions of the Crown in its relation to the Commonwealth and the States, necessarily SO far binds the Crown; and laws validly made under the authority of the Constitution bind, SO far as they purport to do so, both the Crown in right of the States and subjects.
Where the affirmative terms of a power stated in the Constitution would justify an Act of the Parliament of the Commonwealth, it rests upon those who rely on some limitation or restriction of the power, to indicate it in the Con-
Sec. 107 of the Constitution continues the previously existing powers of the Parliaments of the States to legislate with respect to State exclusive powers and State powers which are concurrent with Commonwealth powers; but does not reserve any power from the Commonwealth which falls fairly within the explicit terms of an express grant in sec. 51, as that grant is reasonably con- strued, unless that reservation is as explicitly stated.
Sec. 109 of the Constitution gives supremacy to every Commonwealth Act over every State Act, whether the latter be passed under a concurrent power or under an exclusive power, if any provisions in the two conflict.
Whether the operations of a State Government in the exercise of the prerogative of the Crown, that is, the power of the Crown apart from statutory authority, are subject to any of the powers conferred upon the Commonwealth Parliament by sec. 51 of the Constitution not considered.
The rule laid down in D'Emden v. Pedder, I C.L.R., 91, at p. 111, that when a State attempts to give to its legislative or executive authority an operation which, if valid, would fetter, control, or interfere with, the free exercise of the legislative or executive power of the Commonwealth, the attempt, unless expressly authorized by the Constitution, is to that extent invalid and inoperative," on the basis of the supremacy of Commonwealth legislation created by sec. 109 of the Constitution, is sound.
Deakin v. Webb, 1 C.L.R., 585, and Baxter v. Commissioners of Taxation (N.S.W.), 4 C.L.R., 1087, so far as they decide that the taxation by a State of money received by a Federal officer as salary from the Commonwealth is invalid as being an interference with a Federal instrumentality, overruled.
Federated Amalgamated Government Railway and Tramway Service A880- ciation v. New South Wales Railway Traffic Employees' Association, 4 C.L.R., 488, overruled.
