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…”
DUTY OF TRIAL COURT; PERCEPTION & EVALUATION OF EVIDENCE
There is a duty in a trial court to receive all available relevant evidence on an issue. This is perception of evidence. After that there is another duty to weigh that evidence in the context of the surrounding circumstances of the case. This is evaluation of evidence. A finding of fact will entail both perception and evaluation. But very often in actual practice it is difficult to say when perception ends and evaluation begins.
