as required by the objection in hand. There might be no State
Court having the required jurisdiction, but one might be subse-
quently created by the State. And the matters in which jurisdiction
may be exercised may not exist in law for years to come, if ever.
True it is that there is nothing said in sec. 39 about an intervening
proclamation by the Governor-General, whose action can be con-
trolled as an Executive by the Parliament. But there is, as to
future Courts and even as to the alteration of presently existing
Courts, the necessary intervening action of State Parliaments and
State Executives, outside the control of the Commonwealth Parlia-
ment. The "investing" is not confined to instant operation.
Nor can it possibly be so confined in any case. You cannot, in the
sense suggested, invest "' jurisdiction " - which is to be distinguished
from judicial power - even on an existing Court, in respect of subject
matters that do not yet exist. The " matters " in which jurisdiction.
is to be exercised may never come into legal potentiality, much less
actual existence, for years after the investing enactment is passed.
And as the provision in sec. 39 is a standing provision constantly
speaking in the present (see Halsbury, vol. xxvtt., p. 208, and Craies,
4th ed., at p. 29), the identification of a given State Court depends
on the circumstances as they exist at the moment when jurisdiction
is exercised. Prior to that event, and perhaps since the passing of
the Act, new Courts may have come into existence, old Courts have
been abolished or remodelled, jurisdiction extended or restricted,
and it would be impossible to say that in 1903, when that Act was
passed, the State Courts pointed to by sec. 39 were all in effect
enumerated and inalterable. Never in the whole history of this
Court has it even been suggested that a State Court exercising
Federal jurisdiction under sec. 39 must be one of the Courts identifi-
able on 25th August 1903 or with its jurisdiction in all respects as
then identifiable. Again, there are a host of special statutory
provisions of the same character. For instance, sec. 245 of the
Customs Act 1901, permitting certain prosecutions to be instituted
in "any County Court District) Court Local Court or Court of
summary jurisdiction." It is, I should have thought, beyond
controversy that Courts as described (though not identified), if
