Evidence must not be excluded in detention order proceedings on the ground that it is hearsay (of whatever degree).
Sections 2 to 4 of the Civil Evidence Act 1995 apply in relation to detention order proceedings as those sections apply in relation to civil proceedings.
Detention order proceedings are proceedings—
for an order under section 47M;
for the discharge or variation of such an order;
on an appeal under section 47O.
Hearsay is a statement which is made otherwise than by a person while giving oral evidence in the proceedings and which is tendered as evidence of the matters stated.
Nothing in this section affects the admissibility of evidence which is admissible apart from this section.
