Crown Court rules may, subject to subsection (1) above, prescribe the number of justices of the peace constituting the Court on any hearing within subsection (1)(a) or (b) above, and may prescribe the qualifications to be possessed by any such justices of the peace ; and the rules may make different provision for different descriptions of cases, different places of sitting or other different circumstances.

Without prejudice to the provisions of subsection (1) above, any jurisdiction or power of the Crown Court may be exercised by a judge of the High Court, Circuit judge or Recorder sitting with not more than four justices of the peace.

Subject to the provisions of subsections (1) and (2) above, the cases or classes of cases suitable for allocation to a court comprising justices of the peace (including those by way of trial on indictment which are suitable for allocation to such a court) shall be determined in accordance with directions given by or on behalf of the Lord Chief Justice with the concurrence of the Lord Chancellor.

The Lord Chancellor may from time to time, having regard to the number of justices, or the number of justices with any prescribed qualifications, available for service in the Crown Court, give directions providing that, in such descriptions of proceedings as may be specified by the Lord Chancellor, the provisions of subsections (1) and (2) above shall not apply.

Directions under this subsection may frame descriptions of proceedings by reference to the place of trial, or by reference to the time of trial, or in any other way.

Crown Court rules may authorise or require a judge of the High Court, Circuit judge or Recorder, in such circumstances as are specified by the rules, to enter on, or at any stage to continue with, any proceedings with a court not comprising the justices required by subsections (1) and (2) above or at any stage to continue with any proceedings with a court from which any one or more of the justices initially comprising the court has withdrawn, or is absent for any reason.

No decision of a court shall be questioned on the ground that it was not constituted as required by subsections (1) and (2) above unless objection was taken on that ground by or on behalf of a party to the proceedings not later than the time when the proceedings were entered on, or when the alleged irregularity began.

A justice of the peace shall not be disqualified from acting as a judge of the Crown Court for the reason that the proceedings are not at a place within the area for which he was appointed as a justice, or because the proceedings are not related to that area in any other way.
