The Supreme Court may make an order for the interim detention of an
eligible offender (called an
"interim detention order" ) if, in proceedings on an application for a
continuing detention order, it appears to the Court--
(a) that the offender's current custody (if any) will expire before the proceedings are determined, and
(b) that the matters alleged in the supporting documentation would, if proved, justify the making of an extended supervision order or continuing detention order.
