Oputa, JSC in Ikemson V State (1989) LPELR-1473(SC) at 44 where he magisterially intoned as follows – “Two witnesses who saw the same incident are not bound to describe it in the same way. There is bound to be slight differences in their accounts of what happened. When their stories appear to be very similar, the chances are that those were tutored or tailored witnesses. Minor variations in testimony seem to be a badge of truth. But when the evidence of witnesses violently contradict each other, then that is a danger signal. A trial Court should not believe contradictory evidence. Contradictory means what it says – contra-dictum – to say the opposite.”
ESSENTIAL REQUIREMENTS TO IMPEACH CREDIBILITY OF A WITNESS AS TO CONTRADICTION
Section 232 of Evidence Act, 2011 is intended to check the double-speak of a witness, who is prevaricating on an issue that he had made previous statement in writing on. There are essential requirements of the Section that the party cross-examining a witness, who intends to impeach the credit of the witness by showing that what the witness is presently saying contradicts his previous statement in writing, must comply with. That is, (a) the attention of the witness must be specifically drawn to those parts or portions of his previous statement in writing which are to be used for the purpose of contradicting him; (b) the witness must be reminded of what he had stated in the previous statement, and (c) he must be given an opportunity of making explanation on the apparent contradictions. From the authoritative stance of this Court those are the templates the cross-examiner shall comply with before he tenders any previous statement in writing by a witness for the purpose of contradicting the witness and impeaching his credibility. See MADUMERE v. OKAFOR (1996) 4 NWLR (pt.445) 637; AMODU V. THE STATE (2010) 2 NWLR (pt.1177) 47.
