Three prominent considerations tending to work against adducing fresh evidence at the appellate Court, when this Court exercises its power under Order 2, Rule 12 of the Rules of this Court in that regard, are –
i. Where issues are joined on pleadings at the trial Court no party shall be taken by surprise. Thus, the Appeal Court cannot consider the reception of new evidence without amendment of the pleadings. See ONIBUDO v. AKIBU (1982) 7 SC. 60; ADELEKE v. ASHERIFA (1990) 3 NWLR (Pt.136) 94 at 111; (1990) 21 NSCC 145 at 154.
ii. It is in the interest of public policy, particularly for the purpose of efficient and effective administration of justice, to obviate prolongation of litigation that the practice of adducing evidence, which ought to have been adduced at the trial Court, should not be postponed to after judgment: See ADELEKE v. ASHERIFA (supra).
iii. Appellate Courts generally exercise their jurisdiction to correct errors of law or fact made by the Courts below, after the latter’s consideration of the totality of evidential materials before them. Accordingly, the correctness of the decision of a trial Court or Judge should not be assessed or judged on the new evidence that the trial Court or judge never had an opportunity to consider: See ADELEKE v. ASHERIFA (supra). In other words the correctness or otherwise of the judgment of the trial Judge or Court should not be assessed on evidential materials he or it never had opportunity to consider.
