274.
—(1) As regards a statement in a document or made by a person in any other form than a document, if the parties to any criminal proceedings agree at a hearing that for the purpose of those proceedings the statement may be given in evidence, then, unless the court otherwise directs, the statement is admissible in those proceedings and in any proceedings arising out of them (including any appeal or retrial) as evidence of any fact stated therein.
(2) An agreement under subsection (1) does not enable a statement to be given in evidence under this section on the prosecution’s behalf unless at the time the agreement is made the accused or any of the co-accused is represented by an advocate.
(3) An agreement under subsection (1) shall be of no effect for the purpose of any proceedings before the High Court or any proceedings arising out of proceedings before the High Court if made during proceedings before an examining Magistrate conducting a committal hearing under Division 2 of Part X.
(4) Where in any criminal proceedings a statement in a document is admissible under this section, it may be proved by the production of that document or (whether or not that document is still in existence) by the production of a copy of that document, or of the material part of it, authenticated in a manner approved by the court.
(5) Where a statement is given in evidence under this section but might have become admissible in evidence under section 270 or 272, section 273(4) applies to it as if it were admissible under section 270 or 272, as the case may be.
