Cross-examination is an acid-test of the truthfulness of Evidence of witness
Under the Code of Criminal Procedure, whether it is a trial before a Court of Session or a trial or warrant cases by Magistrates there are specific provisions prescribing the mode of recording evidence with the right of cross- examination of any witness by the accused as contemplated under Sections 244 as well as Sections 273, 275 and 276 of the Code. Both under the sessions trial and trial of warrant cases, the accused is given a discretionary right of deferring the cross examination of any witness or recalling any witness for further cross-examination [vide Sections 231(2), proviso to Section 242 sub-section (3)].
278. Section 137 of the Evidence Act defines what cross- examination means and Sections 139 and 145 speak of the mode of cross-examination with reference to the documents as well as oral evidence. It is the jurisprudence of law that cross-examination is an acid-test of the truthfulness of the statement made by a witness on oath in examination-in-chief, the objects of which are :
(1) to destroy or weaken the evidentiary value of the witness of his adversary;
(2) to elicit facts in favour of the cross- examining lawyer's client from the mouth of the witness of the adversary party;
(3) to show that the witness is unworthy of belief by impeaching the credit of the said witness;
