(1)Subject to subsections (2) and (3) below, a person charged with an offence in summary proceedings shall not be detained in that respect for a total of more than 40 days after the bringing of the complaint in court unless his trial is commenced within that period, failing which he shall be liberated forthwith and thereafter he shall be for ever free from all question or process for that offence.
(2)The sheriff may, on application made to him for the purpose, extend the period mentioned in subsection (1) above and order the accused to be detained awaiting trial for such period as he thinks fit where he is satisfied that delay in the commencement of the trial is due to—
(a)the illness of the accused or of a judge;
(b)the absence or illness of any necessary witness; or
(c)any other sufficient cause which is not attributable to any fault on the part of the prosecutor.
(3)The grant or refusal of any application to extend the period mentioned in subsection (1) above may be appealed against by note of appeal presented to the High Court; and that Court may affirm, reverse or amend the determination made on such application.
(4)For the purposes of this section, a trial shall be taken to commence when the first witness is sworn.
