(1) This section applies if—
(a) a young offender is currently subject to a supervision condition under a good behaviour order (an "existing order"); and
(b) the court makes a further good behaviour order that includes a supervision condition (a new order ).
(2) The court may direct how the new order and the existing order work together.
(3) However, the new order must not require the
young offender to be supervised as stated in the order for longer than 3
years.
