PART III - PRODUCTION AND EFFECT OF EVIDENCE CHAPTER 3 - EXAMINATION OF WITNESSES
Section 112. Impeaching credit of witness
The credit of a witness may be impeached in the following ways by the adverse party or, with the consent of the Court, by the party who calls him:
(a) by the evidence of persons who testify that they from their knowledge of the witness believe him to be unworthy of credit;
(b) by proof that the witness has been bribed, or has accepted the offer of a bribe, or has received any other corrupt inducement to give his evidence;
(c) by proof of former statements inconsistent with any part of his evidence which is liable to be contradicted.
Explanation--- A witness declaring another witness to be unworthy of credit may not, upon his examination-in-chief, give reasons for his belief, but he may be asked his reasons in cross-examination, and the answers which he gives shall not be contradicted, though, if they are false, he may afterwards be charged with giving false evidence.
