It is a basic principle of law that the evaluation of evidence and the ascription of probative value to such evidence are the primary functions of a court of trial which saw, heard and assessed the witnesses while they testified before it. The trial court has the exclusive jurisdiction on matters of appraising evidence and ascribing probative value to the evidence of witnesses whom it had the opportunity of seeing, hearing and observing while in the witness box. Where a court of trial unquestionably evaluates the evidence and justifiably appraises the facts and arrives at a conclusion on the credible evidence, the appellate court will not interfere with such findings of fact nor is it the business of such appellate court to substitute its own views of the facts for those of the trial court. What the appellate court ought to do is to scrutinise the record carefully and find out whether there is evidence on which the trial court could have acted. Once there is such evidence on record from which the trial court arrived at its findings of fact, the appellate court cannot interfere with such findings. See: Mufutau Bakare v.
