"(1) In any criminal proceedings, other than committal proceedings, a written statement by any person shall, if such of the conditions mentioned in the next following subsection as are applicable are satisfied, be admissible as evidence to the like extent as oral evidence to the like effect by that person. (2) The said conditions are - (a) the statement purports to be signed by the person who made it; (b) the statement contains a declaration by that person to the effect that it is true to the best of his knowledge and belief and that he made the statement knowing that if it were tendered in evidence, he would be liable to prosecution if he wilfully stated in it anything which he knew to be false or did not believe to be true; (c) before the hearing at which the statement is tendered in evidence, a copy of the statement is served, by or on behalf of the party proposing to tender it, on each of the other parties to the proceedings; and (d) none of the other parties or their solicitors, within seven days from the service of the copy of the statement, serves a notice on the party so proposing objecting to the statement being tendered in evidence under this section. (8) A document required by this section to be served on any person may be served (a) by delivering it to him or to his solicitor."
