Cause of action has been defined as the facts or combination of facts which give rise to a right to sue. In the case of: Afolayan v. Ogunrinde (1990)1 NWLR (Pt. 127) p. 369, the Supreme Court per Obaseki, J.S.C., (of blessed memory) held thus: In its simplest terms, I would say that a cause of action means (1) a cause of complaint; (2) a civil right or obligation fit for determination by a Court of law; (3) a dispute in respect of which a Court of law is entitled to invoke its judicial powers to determine. It consists of every fact which would be necessary for the plaintiff to prove, if traversed, in order to support his right to judgment. Therefore, a cause of action is the bundle or aggregate of facts which law and equity will recognize as giving the plaintiff a substantive right to make the claim for the relief or remedy being sought. Thus, the factual situation on which the plaintiff relies to support his claim must be recognized by law and or equity as giving rise to a substantive right capable of enforcement or being claimed against the defendant. See the cases of: (1) Ogbimi v. Ololo (1993) 7 NWLR (Pt. 304) p. 128; (2) Bello v. A.-G., of Oyo State (1986) LPELR 764 and (3) Cookey v. Fombo (2005) 15 NWLR (Pt. 947) p. 182.
