Para. 21: “A cause of action is a set of facts sufficient to justify a right to sue. It must contain a clear and concise statement of the material facts upon which the pleader relies for his claim with sufficient particularity to enable the opposite party to reply thereto. The term “cause of action” was defined in McKenzie v Farmers’ Co-operative Meat Industries Ltd 1922 AD 16 at 23 as “…”every fact which would be necessary for the plaintiff to prove, if traversed, in order to support his right to the judgment of the Court. It does not comprise every piece of evidence which is necessary to prove each 22 fact, but every fact which is necessary to be proved.” See also Mousa Leo Keita (2004-2009) CCJELR pg. 75 See also Afolayan V. Oba Ogunrinde & 3 ORS, (1990), 1 NWLR, (Pt. 127) 369 @ 371. SCNJ 62. Where Karibi-Whyte JSC stated that a cause of action means: ‘a) A cause of complaints; b) A civil right or obligation for the determination by a Court of law; c) A dispute in respect of which a Court of law is entitled to invoke its judicial powers to determine.’”
