There is no doubt that the evaluation of evidence and ascription of probative value thereto are the primary duties of the trial court, which had the singular opportunity of seeing and hearing the witnesses testify and an appellate court would ordinarily not interfere. It is also trite that this court will not interfere with concurrent findings of fact by two lower courts, unless it is shown that the findings are perverse, or not based on a proper and dispassionate appraisal of the evidence, or that there is an error, either of law or fact, which has occasioned a miscarriage of justice.

Fashola (2008) All FWLR (Pt. 443) 1302, (2008) 6 NWLR (Pt. 1082) 90 at 153- E.
