ESSENTIAL REQUIREMENTS TO IMPEACH CREDIBILITY OF A WITNESS AS TO CONTRADICTION

ONLY MATERIAL CONTRADICTIONS ARE IMPORTANT TO SET ASIDE DECISION

The contradiction complained about by the learned counsel for the Appellant is very insignificant. It is not any and every minor discrepancy or inaccuracy in the evidence of prosecution witnesses that amount to contradiction, especially where the witnesses are in substance saying the same thing. It is only material contradiction that is important. See The State vs Azeez & Ors 4 SC 188: Dibie & 2 Ors vs The State (2007) 3 SC (Pt. 1) 176.

ONLY SUBSTANTIAL CONTRADICTIONS CREATES DOUBT

The law further requires that whatever evidence the respondent relies on in proving its case against the appellant, it must be bereft of substantial contradictions. Only material contradictions in respect of a fact in issue creates doubt in the mind of the Court thereby destroying the case sought to be established against an accused. Thus, only such material contradictions which affect live issues to which they relate avail an opposing party thereby entitling the appellate Court to interfere with the judgment on appeal giving the miscarriage of justice they occasion. See Maiyaki V. The State 2008) LPELR-1823 (SC), Sele V. The State 1 SCNJ (Pt. 1) 15 at 22 23 and Usiobaifo & Anor V. Usiobaifo (2005) LPELR-3424 (SC).

COUNSEL ALLEGING CONTRADICTION IN COURT’S JUDGEMENT MUST POINT TO THE SAID CONTRADICTIONS

Now, in the first place, it is significant and most remarkable, that the learned counsel for the Appellant, in their Brief, did not point out or identify, one single evidence of any contradiction either in the evidence of the prosecution witnesses or in any documentary evidence tendered before the trial court. I suppose, and with respect, this is commonsensical, that it is not enough or sufficient to complain or allege contradictions, without indicating the areas of any such material contradiction or contradictions either in the evidence of the prosecution witnesses or in the totality of the admissible evidence before a trial court.

ONLY CONTRADICTIONS ON MATERIAL POINTS ARE RELEVANT

I have given careful consideration to the contradictions and inconsistencies highlighted in appellant’s brief. The law is clear. It is not every contradiction in the evidence of witnesses called by a party that is fatal to the party’s case but only those contradictions on material points – Nasama v. The State (1979) 6-9 S.C. 153; R. v. Ekanem 5 F.S.C. 14, (1960) SCNLR 42; Kalu v. State (1988) 4 NWLR (Pt.90) 503.

TWO EVIDENCE CONTRADICT ONE ANOTHER WHEN THEY AFFIRM THE OPPOSITE

A piece of evidence contradicts another when it affirms the opposite of what that other evidence has stated not when there is just a minor discrepancy between them. Two pieces of evidence contradicts one another when they are themselves inconsistent. A discrepancy may occur when a piece of evidence stops short of, or contains a little more than what the other evidence says or contains some minor difference in details. See Gabriel v State (1989) 5 NWLR (Pt.122) p.460. If a witness makes a statement before trial which is inconsistent with the evidence he gives in Court and he does not explain the inconsistency to the satisfaction of the Court, the Court should regard his evidence as unreliable. See Onubogu & Anor v State (1974) (NSCC) p.358. I must say straightaway that it is only material contradictions that are to be considered.

WHERE PROSECUTION CASE CONTRADICTS, COURT MUST REJECT BOTH, EXCEPT PROSECUTION LAY FOUNDATION

In Onubogu v. State (1974) 9 SC 1, this court per Fatayi-Williams, JSC (as he then was) said at page 20: “We are also of the view that where one witness called by the prosecution in a criminal case contradicts another prosecution witness on a material point, the prosecution ought to lay some foundation, such as showing that the witness is hostile, before they can ask the court to reject the testimony of one witness and accept that of another witness in preference for the evidence of the discredited witness. It is not competent for the prosecution which call them to pick and choose between them. They cannot, without showing clearly that one is a hostile witness, discredit one and accredit the other. (See Summer and Leivesley v. Brown & Co. (1909) 25 TLR 745). We also think that, even if the inconsistency in the testimony of the two witnesses can be explained, it is not the function of the trial Judge, as was the case here, to provide the explanation. One of the witnesses should furnish the explanation and thus give the defence the opportunity of testing by cross-examination, the validity of the proffered explanation.”
