Criminal Procedure (Attendance of Witnesses) Act 1965

2 Summons to witness to attend court of assize or quarter sessions

(1) For the purpose of any criminal proceedings before a court of assize or quarter sessions a witness summons, that is to say, a summons requiring the person to whom it is directed to attend before the court and give evidence or produce any document or thing specified in the summons, may be issued out of that court or out of the High Court.

(2) If any person in respect of whom a witness summons has been issued applies to the court out of which the summons was issued or to the High Court, and satisfies the court that he cannot give any material evidence or, as the case may be, produce any document or thing likely to be material evidence, the court may direct that the summons shall be of no effect.

(3) The provisions of Schedule 1 to this Act shall have effect in relation to applications under the last foregoing subsection.
