137.—(1) In this section “dual order” means an order which requires a child either—

( a) to be under the supervision of a probation and welfare officer for a specified period, or

( b) to attend at a day centre for a specified period not exceeding 90 days,

and which also restricts the child’s movements for a specified period not exceeding 6 months.

(2) The court may make a dual order where it is of opinion that neither supervision by a probation and welfare officer nor attendance at a day centre, including any conditions to which such supervision or attendance would be made subject, would of itself adequately reduce the likelihood of the child committing further offences.

(3) A dual order shall be deemed for all purposes—

( a) in so far as it imposes a requirement mentioned in subsection (1)(a), to be a probation order,

( b) in so far as it imposes a requirement mentioned in subsection (1)(b), to be a day centre order, and

( c) in so far as it restricts a child’s movements, to be an order under section 133 .
