Pam vs. Gwom (2000) FWLR 9Pt.1) 1 at 12 that: “The right of appeal from the Customary Court of Appeal to the Court of Appeal is as of right and must relate to any question of Customary Law and/or such other matters as may be prescribed by an Act of National Assembly that can extend this right by providing for such matters. Neither the Federal Military Government nor the National Assembly, made such other provision as envisaged in Section 224(1) of the 1979 Constitution. In the circumstances, for an appeal from the Customary Court of Appeal to the Court of Appeal to be competent, it must raise a question of Customary Law.”
Ayoola JSC: “The question therefore is: when is a decision in respect of a question of Customary Law? I venture to think that a decision is in respect of Customary Law when the controversy involves a determination of what the relevant Customary Law is and the application of the customary Law so ascertained to the question in controversy… When the decision of the Customary Court of Appeal turns purely on facts, or a question of procedure, such decision is not with respect to a question of Customary Law, not withstanding that the applicable law is Customary Law.”
CUSTOMARY LAW IS A QUESTION OF FACT TO BE PROVED
It is well settled that customary law is a question of fact to be proved by evidence. See Section 14 of Evidence Law. Hence a party who alleges the existence of a particular custom must adduce sufficient evidence in support and to establish its existence to the satisfaction of the court. See Inyang v Ita (1929) 9 NLR 84. But there comes a time when by frequent litigation in the courts, a point of customary law has been sufficiently ruled upon, the courts will no longer require proof, and would be prepared to take judicial notice of it. See Angu v Attah, PC 74, 28, 43; Buraimo v Gbamgboye (1940) 15 NLR 139; Giwa v Erimolokun (1961) 1 All NLR 294, 1 SCNLR 337. The burden is on the defendants to establish the custom they rely upon for their defence. Balogun v Labiran (1988) 3 NWLR (Part 80) 66. Indeed only a single decision, sufficiently cogent and authoritative would be sufficient – Larinde v Afiko (1940) 6 WACA 108, but see Cole v Akinyele (1960) 5 FSC 84; (1960) SCNLR 192; Folami & others v Cole & others (1990) 2 NWLR (Part 133) 445.
