The law remains that an Appellate Court is reluctant to upset a finding of fact made by a trial court which had the opportunity of listening to witnesses testify and observing their demeanour and that evaluation of evidence and the ascription of probative value thereto are the primary functions of a trial court which saw, heard and assessed the witnesses. Where a trial court clearly evaluated the evidence of the parties and justifiably appraised the facts, it is not the business of an Appellate Court to substitute its own views of the facts for those of the trial court. It is only where the trial court is proved to have abdicated this function or in carrying out the function makes an unsound finding that an Appellate Court can justifiably step in to do so or set aside such unsound finding for being perverse.
