The Supreme Court has held in Layade v. Panalpina (1996) 6 NWLR (Pt. 456) 544 at 558; (1996) 7 SCNJ 1 at 14-15 per Adio. J.S.C., as follows and I quote; ”The general rule is that where parties have embodied the terms of their agreement or contract in a written document, as it was done in this case, extrinsic evidence is not admissible to add to, vary, subtract from or contradict the terms of the written instrument … So, where the parties enter into a contract, they are bound by the terms of that contract and it is unfair to read into such a contract the terms on which there was no agreement.”
COURT WILL ACT ON UNCHALLENGED EVIDENCE
The law is well settled that where the evidence given by a party to any proceedings was not challenged by the opposite party who had the opportunity to do so, it is always open to the court seised of the case to act on such unchallenged evidence before it.
