In the case of AWUSA v. NIG. ARMY (2018) LPELR-44377 (SC) the Apex Court held that: “The position of the law is that when an Appellant alleges that a decision is against the weight of evidence, he means that when evidence he adduced is balanced against that of the Respondent. Judgment in the Respondent’s favour is against the weight that should have been given to the totality of the evidence adduced – See Akinlagun v. Oshoboja (2006) 12 NWLR (Pt. 993) 60 at 82 SC. The complaint is only concerned with appraisal and evaluation of all the evidence and not the weight to be attached to any particular piece of evidence…”
WHAT APPELLANT MUST DO WHEN HE ALLEGES FAULTY EVALUATION OF EVIDENCE
Evaluation of evidence entails the trial Judge examining of all evidence before him before making a finding. This is done by putting all the evidence on an imaginary scale to see which side outweigh the other by way of credible evidence. See LAFIA L. G. v. EXEC. GOV. OF NASARAWA STATE (2012) LPELR-20602 (SC). So where the Appellant complained that the judge did not evaluate evidence properly as in this case, he has the duty to show the Appellate Court how the correction of the omission will make the decision wrong and liable to be set aside. For example, the Appellant must show which admissible evidence the trial Judge rejected or inadmissible evidence he relied upon to the extent that resulted in a miscarriage of justice. In other words, it is not just enough to complain against the evaluation of evidence, but the Appellant must show that the decision of the trial Court was wrong. See PETROLEUM (SPECIAL) TRUST FUND v. WESTERN PROJECT CONSORTIUM LTD and ORS. (2006) LPELR-7719 and ODUNUKWE v. OFOMATA and ANOR. (1999) 6 NWLR (PT. 602) 416 at 425 (CA). The law has been stated and re-stated in uncountable number of decisions of this Court and the Supreme Court that the duty of evaluation of evidence and the ascription of probative value to such evidence is the primary duty of the trial Court. This is especially so where the evaluation of evidence is on the conflicting oral testimonies and belief or disbelief of such evidence. The Appellate Court cannot be in a position to recapture that advantage that the trial Judge had in observing the witnesses as they testified. Therefore, unless the Appellant satisfied this Court as an Appellate Court that the decision of the trial Court was wrong vide improper evaluation of evidence, we have no business re-evaluating the evidence to substitute our own decision for that of the trial Court.
