It is urged, however, that the Court should follow and apply
certain statements that the defence power is exclusive to the Com-
monwealth which are to be found in decisions of this Court. In
Commissioners of Taxation (N.S.W.) v. Baater (2) there is a sugges-
tion that the defence power is exclusive, but, upon examination, it
will be seen that this statement relates only to what I have called
the exclusive power, in a modified sense, to raise and maintain
forces. Further, the statement is obiter, as, indeed, are all the state-
ments which were relied upon in this connection. In Farey vy. Bur-
vett (3) Isaacs J. said that "' to make defence adequate and successful
full power must be within the grasp of one hand." But " full power"
is not the same thing as " exclusive power," and the learned judge
explicitly stated that " the States may, in directions not contraven-
ing express prohibitions, most advantageously act by means of their
own constitutional powers in aid of the common object " - i.e., the
defence of the Commonwealth. (Sec. 114 is an example of the
"express prohibitions " to which reference is made.) In Joseph v.
Colonial Treasurer (N.S.W.) (4), there is a statement that the
defence power is exclusive to the Commonwealth. But this state-
ment in its full generality was not necessary to the decision of the
case, and should be limited to the aspect of the defence power
which was in question, namely, the exercise by the Executive
Government of the royal war prerogative. The statement in the
(dissenting) judgment of Higgins J. in Australian Workers' Union
v. Adelaide Milling Co. Ltd. (5) that "the State of Victoria has
not the war power" in its strict sense means no more than that
the power to declare or make war does not belong to the States.
It was not, I think, intended to mean that a State Parliament cannot
pass any Act to assist in the defence of the Commonwealth. For
reasons which I have already stated I find myself unable to agree
with the statements of Knox C.J. and Isaacs J. in Pirrie v. McFarlane
(6) that the defence power is exclusive. These statements were
