The treatment of traditional evidence or history has over the years come to be regulated by what I may call the rule in Kojo II v. Bonsie (1957) 1 NMLR 1223. The proposition of law relating to traditional evidence as decided in Kojo II v. Bonsie is that where there is a conflict of traditional history, demeanour by itself, is of little guide to the truth. The best way to test the traditional history is by reference to the facts in recent years as established by evidence and by seeing which of the two competing histories is more probable.
