It is trite that litigation, particularly election dispute litigation, is fought on pleadings. Parties swim or sink with their pleadings. In the case of ANYAFULU & ORS V. MEKA & ORS (2014) LPELR 22336 (SC), the Supreme Court Per Kekere Ekun, JSC held that: “Litigation is fought on pleadings. They are the pillars upon which a party’s case is founded. Not only do they give the other side notice of the case they are to meet at the trial, they also define the parameters of the case. In other words, parties are bound by their pleadings. Any evidence led on facts not pleaded goes to no issue while any pleadings in respect of which no evidence is led are deemed abandoned. In effect, where the pleadings are deficient no matter how cogent the evidence led, the case would fail. See: Nwokorobia Vs Nwogu (2009) 10 NWLR (1150) 553; Shell B. P. Vs. Abedi (1974) 1 SC 23; Ebosie Vs. Phil Ebosie (1976) 7 SC 119; George Vs Dominion Flour Mill Ltd. (1963) 1 ALL NLR 71.” See also IFEANYICHUKWU OSONDU CO. LTD & ANOR V. AKHIGBE (1999) LPELR (SC). Those pleadings in Paragraphs 41-42 of the Petition having been abandoned are discountenanced.
