17. (1) Where information is given in evidence by virtue of this Chapter—

(a) any evidence which, if the person who originally supplied the information had been called as a witness, would have been admissible as relevant to his or her credibility as a witness shall be admissible for that purpose,

(b) evidence may, with the leave of the court, be given of any matter which, if that person had been called as a witness, could have been put to him or her in cross-examination as relevant to his or her credibility as a witness but of which evidence could not have been adduced by the cross-examining party, and

(c) evidence tending to prove that that person, whether before or after supplying the information, made (whether orally or not) a statement which is inconsistent with it shall, if not already admissible by virtue of section 14 , be admissible for the purpose of showing that he or she has contradicted himself or herself.

(2) This section is without prejudice to provisions in any other enactment concerning evidence as to the credibility of the supplier of information in business records.
