Judgment (32 paragraphs)
For the reasons I have given I hold that the Parliament has power to legislate for the service and execution throughout the Commonwealth of a summons requiring a witness to appear and give evidence at a preliminary examination under Pt V of the Justices Act. The question remains whether s. 16 (2) of the Act is a law of that description. Although the warrant issued under that sub-section is such warrant as might have been issued if the summons had been served in the State in which it was issued, it seems right to say that its issue is authorized by Commonwealth law rather than by State law. Assuming, however, that the warrant issued under s. 16 (2) may not in itself be described as the process of a State, it is issued to enable the process of a State, viz. the summons, to be carried into effect. Although s. 16 (2) appears in a Part of the Act whose heading refers to "Service", it provides, in my opinion, for the execution of the summons served under s. 16 (1). The Constitution does not narrowly limit the mode of execution allowed, but permits the Parliament to select the means by which process of one State is to be given efficacy in another, and to provide if necessary that further process be issued for this purpose. The decision in Aston v Irvine [1] , upholding the validity of s. 18 of the Act, supports this view. A warrant issued in one State, and indorsed in another under s. 18 (1), may be carried into execution by the issue of a further warrant under the authority of s. 18 (3), and by the execution of that further warrant. Any objection to s. 16 (2) on the ground that the Commonwealth statute reposes power in magistrates and justices of the States is also answered by Aston v Irvine [1] . Section 16 (2) is in my opinion a valid law for the execution of the process of the States.
