12.—(1) This paragraph applies where, at any time while a relevant order is in force in respect of an offender, a court of summary jurisdiction acting for the petty sessions district concerned is satisfied that the offender proposes to change, or has changed, his residence from that petty sessions district to another petty sessions district.
(2) Subject to sub-paragraphs (3) and (4), the court may, and on the application of the responsible officer shall, amend the relevant order by substituting the other petty sessions district for the district specified in the order.
(3) The court shall not amend under this paragraph a probation order which contains requirements which, in the opinion of the court, cannot be complied with unless the offender continues to reside in the petty sessions district concerned unless, in accordance with paragraph 13, it either—
(a)cancels those requirements; or
(b)substitutes for those requirements other requirements which can be complied with if the offender ceases to reside in that district.
(4) The court shall not amend a community service order under this paragraph unless it appears to the court that provision can be made for the offender to perform work under the order under the arrangements which exist for persons who reside in the other petty sessions district to perform work under such orders.
