COMPETENCY IS A MATTER OF UNDERSTANDING

COURT TO DECIDE CASE ONLY ON LEGALLY ADMISSIBLE EVIDENCE

Thus where a court wrongfully admits inadmissible evidence, it ought as a duty, to disregard the inadmissible evidence in the consideration of the judgment in the matter. Where such evidence has been wrongfully admitted and acted upon and whether or not the opposing party objects or not, an appellate court has the duty to exclude such evidence and decide the case only on the legally admissible evidence, see Timitimi v Amabebe (1953) 14 WACA 374; Ajayi v Fisher (1956) 1 FSC 90, (1956) SC NLR 279.

EXTRINSIC EVIDENCE NOT ALLOWED TO VARY WRITTEN CONTRACT

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.”

SETTLED PRINCIPLES WHICH GUIDE THE COURT WHETHER TO ADMIT FRESH EVIDENCE

As rightly submitted by learned counsel for both parties, there are settled principles, which guide the Court in determining whether to grant leave to adduce fresh or further evidence. They are, inter alia, as follows: (a) The evidence sought to be adduced must be such as could not have been, with reasonable diligence, obtained for use at the trial, or are matters which have occurred after judgment in the trial Court. (b) In respect of other evidence other than in (a) above, as for instance, in respect of an appeal from a judgment after a hearing on the merits, the Court will admit such fresh evidence only on special grounds. (c) The evidence should be such as if admitted, it would have an important, not necessarily crucial effect on the whole case; and (d) The evidence must be such as apparently credible in the sense that it is capable of being believed and it need not be incontrovertible. See: Asabaro vs Aruwaji (1974) 4 SC (Reprint) 87 @ 90 – 91: Akanbi vs Alao (1989) 3 NWLR (Pt.108) 118@ 137 – 138 H – B: Esangbedo vs The State (1989) 4 NWLR (Pt.113) 57 @ 67 A-C.

PRINCIPLES WHICH APPELLATE COURTS SHOULD CONSIDER IN THE EVALUATION OF EVIDENCE

And that takes me to the principles which an Appellate Court should consider in the evaluation of evidence by the trial Judge: 1. Evaluation of trial evidence is the primary responsibility of the trial court and so an Appellate Court cannot interfere just for the asking by an appellant. 2. An Appellate Court will however evaluate the evidence before the court if the trial court fails to do so; and this is from the Record. 3. An Appellate Court will also evaluate the evidence before the court if the trial court failed to evaluate the evidence properly in the sense that the evaluation is perverse. And so, the evaluation of evidence, though the primary responsibility of the trial court, is not the exclusive preserve of that court. It becomes so only where the evaluation is borne out from the evidence before the court.
