9.—(1) This paragraph applies where—
(a)an offender in respect of whom a relevant order is in force is convicted of an offence before a court of summary jurisdiction other than a court of summary jurisdiction acting for the petty sessions district concerned; and
(b)the court imposes a custodial sentence on the offender.
(2) If it appears to the court, on the application of the offender or the responsible officer, that it would be in the interests of justice to do so having regard to circumstances which have arisen since the order was made, the court may—
(a)if the order was made by a magistrates' court revoke it; and
(b)if the order was made by the Crown Court, commit the offender to custody or release him on bail until he can be brought or appear before the Crown Court.
(3) Where the court deals with an offender’s case under sub-paragraph (2)(b), it shall send to the Crown Court such particulars of the case as may be desirable.
