In the case of Osondu Co Ltd. and Anor v. Akhigbe (1999) LPELR – 1433 (SC), the Supreme Court per Uwaifo, JSC, held as follows: “It must be realized that pleadings is a statement of candour as to what a party to a case relies on to prove or defend a cause. It ought to be made as clear as it possibly can, not evasive or misleading or ambiguous. Each party must endeavor to place and must be presumed to have placed, all necessary pleadable acts on record the best way it can in order to achieve the best of its case. It must put the other party and the Court on a firm understanding of what the issues joined or denied, or issues admitted or not admitted. Pleadings are the guiding light by which all concerned trace the path to the justice of a case. That path should not be hampered by and littered with stumbling blocks of uncertainties, misrepresentations and ambushes embedded in the averments. That will be an effort to spring surprises and will not be proper pleadings. As was said by Phillimore J., in The Why Not (1888) LR 2A and E. 265 and quoted with approval in Enwezor v. Central Bank of Nigeria (1976) 3 SC 45 at 56 Per Madarikan, JSC, pleadings “…are not to be considered as constituting a game of skill between the advocates. They ought to be so framed as not only to assist the party in the statement of his case but the Court in its investigation of the truth between the litigants.”
NATURE OF PROOF OF PLEADINGS
It must be appreciated that there cannot be a better notice of a case a party intends to make than his pleading. It is a mere notice and can never be substituted for the evidence required in proof of the facts pleaded, subject however to an admission made by the other party. Unless through skilful cross-examination discrediting the case of the other party, he is still bound to lead evidence in support of his own pleading. Where evidence is adduced to buttress a pleading, then it is good news for the pleader, as it strengthens his case. However, evidence adduced in support of facts not pleaded goes to no issue and should therefore be disregarded ORIZU V. ONYAEGBUNAM 1978.5 S.C. 21 at 820. In ACB V. GWAGWALADA 1994. 5 NWLR Part 342 page 25 at 27 it was held that before considering admissibility of any evidence or document in support of a party’s case it must be shown that the evidence sought to be led is relevant. Even if the evidence is admissible and it is not relevant, the admission of such evidence does not advance the case of the party.
