It has long been established that the function of the evaluation of evidence is essentially that of the trial Court, Igago v State (1999) LPELR – 1442 (SC) 27; Onuoha V. The State [1998] 5 NWLR (pt. 548) 118. Where the trial Court has unquestionably, evaluated evidence and, justifiably, appraised the facts, it is not the business of an appellate Court to interfere, and to substitute its own views for the view of the trial Court. – Nweze JSC. Abdullahi v. Adetutu (2019)
NATIVE CUSTOM IS A QUESTION OF FACT
Native law and custom being a question of fact in an action in the High Court, it is true that the findings in these cases are not binding as precedents, and it is also true, as has been pointed out by Mr Oseni on behalf of the respondents, that however learned and experienced the Judges whose judgments are relied on may have been, they could only act on the evidence which the parties in the cases concerned chose to call before them.
