And that takes me to the principles which an Appellate Court should consider in the evaluation of evidence by the trial Judge: 1. Evaluation of trial evidence is the primary responsibility of the trial court and so an Appellate Court cannot interfere just for the asking by an appellant. 2. An Appellate Court will however evaluate the evidence before the court if the trial court fails to do so; and this is from the Record. 3. An Appellate Court will also evaluate the evidence before the court if the trial court failed to evaluate the evidence properly in the sense that the evaluation is perverse. And so, the evaluation of evidence, though the primary responsibility of the trial court, is not the exclusive preserve of that court. It becomes so only where the evaluation is borne out from the evidence before the court.
