Onwu v. Nka (1996) 7 NWLR (Pt.458) 1 at 17 paragraph E, where the Supreme Court, per Iguh JSC. had this to say: “The law is well settled that where disputes or matters in difference between two or more parties are by consent of the disputants submitted to a domestic forum inclusive of arbitrators or a body of persons who may be invested with judicial authority to hear and determine such disputes and matters for investigation in accordance with customary law and general usages, and a decision is duly given, it is as conclusive and unimpeachable (unless and until set aside on any of the recognized grounds) as the decision of any constituted court of the land, such a decision is consequently binding on the parties and the courts in appropriate cases will enforce it.”
COURT OF APPEAL IS BOUND BY HER PREVIOUS JUDGEMENT
This is a hypothetical and an academic question but my answer to the question is in the affirmative, i.e., that the Court of Appeal is bound by its previous judgments. It is also bound by the judgments of the Supreme Court. The Court of Appeal has not contended the contrary. Since the Court of Appeal sits in divisions, now there exists the danger of decisions delivered in one division conflicting with decisions in another division.
