(1)Where so many of the persons who have been indicted for any sitting of the High Court have pleaded guilty at the first diet as to make the holding of a separate court for the cases remaining unnecessary, it shall be lawful for any Lord Commissioner of Justiciary, on the petition of the Lord Advocate, and in chambers and without the presence of the prosecutor or the accused, to order the second diets of such cases to be postponed and to be held at any other sitting of the High Court which is about to be held.
(2)Upon such order for postponement being issued, a notice shall forthwith be served upon the accused, who may have already been cited, in the form set out in Schedule 0 to the [1887 c. 35.] Criminal Procedure (Scotland) Act 1887 or in an Act of Adjournal under this Act or as nearly as may be in such form.
