22Where—
(a)a community service order or combination order is in force in respect of any offender, and
(b)on the application of the offender or the responsible officer, it appears to a magistrates' court acting for the petty sessions area concerned 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, in relation to the order, extend the period of twelve months specified in section 47(3) of this Act.
