It is settled law that the appraisal of facts is the duty of the trial Judge and the Appellant court will only intervene when the finding is perverse or wrongly made. – Nwodo, JCA. OLAM v. Intercontinental Bank (2009)
TWO TYPES OF FINDING OF FACTS – WHEN APPEAL COURT CAN INTERFERE
In a trial, there are generally two sets of findings of facts: A finding of fact may be based on the credibility of witnesses or may be informed from other facts proved before the trial court. Where a witness gives direct evidence that is the evidence of the facts in issue as seen, heard or perceived by any other sense by him. (Section 77 of the Evidence Act). The finding of the trial court on such evidence depends on whether or not it believes that witness (credibility of the witness). Such a finding on such evidence is a primary finding of fact, i.e. the way the witness testifies, his demeanor in the box tells much of his credibility. The trial court that saw and heard the witness is in the best position to assess his credibility and make findings of primary facts. But, where on the other hand, other facts are put in evidence from which the facts in issue can be inferred, or where a witness gave circumstantial evidence, the finding of the trial court on the facts in issue depends on inference. This is a secondary finding of fact as it is not based on the credibility of the witness but on logical process of inference. In the former’s case, i.e. primary findings of fact, an appeal court should always be loathe in interfering with such a finding as it did not have the privilege of seeing, hearing or observing the demeanour of the witness. There are several decided authorities on this: Ebba v. Ogodo & Anor (1984) 4 SC 75; Akintola v. Olowa (1962) 1 All NLR 224; Fatoyinbo v. Williams (1956) 1 FSC 87; Egri v. Uperi (1974) 1 NMLR 22; just to mention a few. In the latter’s case, i.e. where findings of fact are secondary, i.e. drawn from inferences, an appeal court is in as good position as a court of trial to do this. It can differ from the trial court.
