Very much aware of the findings of facts by the two lower courts in this matter, I must state, all the same, that where the evidence to be evaluated is mainly documentary as here, this court is as in good a vintage position as the trial court. – Chukwuma-Eneh JSC. Yaro v. Arewa CL (2007)
EXTRINSIC EVIDENCE CANNOT VARY A WRITTEN CONTRACT
The general rule is that where the parties have embodied the terms of their contract in a written document, extrinsic evidence is not admissible to add to, vary, subtract from or contradict the terms of the written instrument.
– Adio, JSC. UBN v. Ozigi (1994)
