When any sitting of the sheriff court or of the High Court has been appointed to be held for the trial of persons accused on indictment, the sheriff clerk of the district in which the second diet is to be called, where such trials are to take place in the sheriff court, or the Clerk of Justiciary, where such trials are to take place in the High Court, shall issue a warrant to officers of law to cite persons accused, witnesses, and jurors, conform to Schedule B to the [1887 c. 35.] Criminal Procedure (Scotland) Act 1887 ; and the execution of the citation against such accused persons shall be conform to Schedule C to that Act; and the execution of the citation of witnesses shall be conform to Schedule D to that Act; and the execution of the citation of jurors shall be conform to Schedule E to that Act; and such warrant authenticated by the signature of such clerk, or a duly certified copy thereof, shall be a sufficient warrant to all officers competent.
The warrant and the executions mentioned in this section may, instead of being conform to the said Schedules B to E, be in the form set out in an Act of Adjournal under this Act or as nearly as may be in such form.
