In Peter Igho v. The State (1978) 3 SC 87 the facts as set out in the judgment were that the deceased, lfoto Oboluke, left her house on Sunday 20th August, 1972 for a religious service but never returned alive. When the mother did not see her return in the evening she made a report and a search party was organised by the villagers. Those who saw her last said she was riding at the back of a bicycle. The corpse of the deceased was later found that night. This Court per Eso JSC upholding the verdict of the trial court on the conviction of the appellant said: “The only irresistible inference from the circumstances presented by the evidence in this case is that the appellant killed the deceased. We can find no other reasonable inference from the circumstances of the case. The facts which were accepted by the learned trial Judge amply supported by the evidence before him, called for an explanation and beyond the untrue denials of the appellant (as found by the learned trial Judge) none was forthcoming. See R. v. Mary Ann Nash (1911) 6 C.A.R. 225 at page 228. Though this constitutes circumstantial evidence, it is proof beyond reasonable doubt of the guilt of the appellant.”
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.
