(a) by a party to the proceedings, or

(b) by the court of its own motion,

shall be determined by the court in accordance with this section.

(2) The witness may not be sworn for that purpose unless—

(b) he has a sufficient appreciation of the solemnity of the occasion and of the particular responsibility to tell the truth which is involved in taking an oath.

(3) The witness shall, if he is able to give intelligible testimony, be presumed to have a sufficient appreciation of those matters if no evidence tending to show the contrary is adduced (by any party).

56 Reception of unsworn evidence. E+W

(1) Subsections (2) and (3) apply to a person (of any age) who—

(2) The evidence in criminal proceedings of a person to whom this subsection applies shall be given unsworn.

(3) A deposition of unsworn evidence given by a person to whom this subsection applies may be taken for the purposes of criminal proceedings as if that evidence had been given on oath.

(4) A court in criminal proceedings shall accordingly receive in evidence any evidence given unsworn in pursuance of subsection (2) or (3).

(5) Where a person (“the witness”) who is competent to give evidence in criminal proceedings gives evidence in such proceedings unsworn, no conviction, verdict or finding in those proceedings shall be taken to be unsafe for the purposes of any of sections 2(1), 13(1) and 16(1) of the Criminal Appeal Act 1968 (grounds for allowing appeals) by reason only that it appears to the Court of Appeal that the witness was a person falling within section 55(2) (and should accordingly have given his evidence on oath).

57 Penalty for giving false unsworn evidence. E+W

(1) This section applies where a person gives unsworn evidence in criminal proceedings in pursuance of section 56(2) or (3).

(2) If such a person wilfully gives false evidence in such circumstances that, had the evidence been given on oath, he would have been guilty of perjury, he shall be guilty of an offence and liable on summary conviction to—

(a) imprisonment for a term not exceeding 6 months, or

(b) a fine not exceeding £1,000,

or both.

(3) In relation to a person under the age of 14, subsection (2) shall have effect as if for the words following “on summary conviction” there were substituted “ to a fine not exceeding £250 ”.
