Atolagbe v. Shorun (1985) 1 NWLR (Pt. 2) 360 at 365 where Coker, J.S.C. in dealing with the main function of pleadings in the trial of an action had this to say: – “The primary function of pleadings is to define and delimit with clarity and precision the real matters in controversy between the parties upon which they can prepare and present their respective cases and upon which the court will be called to adjudicate between them. It is designed to bring the parties to an issue on which alone the court will adjudicate between them party is bound by his pleading and cannot go outside it to lead evidence or rely on facts which are extraneous to those pleaded.”
PARTIES AND THE COURT ARE BOUND BY THE PLEADINGS AND ISSUES JOINED
It is settled law that issues for trial by the Court are joined in the pleadings and that parties and indeed the Court are bound by the pleadings of the parties. The Petitioners’ case stands to collapse if no evidence is called on the issue. See ORUWARI V. OSLER (2012) LPELR-19764 (SC) and KUBOR & ANOR V. DICKSON & ORS (2012) LPELR-9817 (SC).
