A serious violence reduction order takes effect on the day it is made, subject to subsections (3) and (4).
A serious violence reduction order must specify the period for which it has effect, which must be a fixed period of not less than 6 months and not more than 2 years.
Subsection (4) applies in relation to a serious violence reduction order if—
the offender has been remanded in or committed to custody by an order of a court, or
a custodial sentence has been imposed on the offender or the offender is serving or otherwise subject to a such a sentence.
The order may provide that it does not take effect until the offender is released from custody or ceases to be subject to a custodial sentence.
Where a court makes a serious violence reduction order and the offender is already subject to such an order, the earlier order ceases to have effect.
