Now, it is undeniable that Section 294 (1) of the Constitution of the Federal Republic of Nigeria consecrates the right to final addresses. Sodipo v. Lemminkainen Oy [1985] 2 NWLR (pt 8) 547; Mustapha v. Governor of Lagos State (1987) 2 NWLR (Pt. 58) 539; Ijebu Ode v. Balogun and Company Ltd. (1991) LPELR 1463 (SC) 31-32; F-A; Okeke v. State (2003) LPELR-2436 (SC) 19-20; F-A. The said expression “final addresses” means the last or ultimate speech or submission made to the Court in respect of the matter before it, before the delivery of the judgment. Put simply, it is the last address before the delivery of the judgment. Sodipo v. Leminkainen Oy (supra); Mustapha v. Governor of Lagos State (supra); Ijebu Ode v. Balogun and Company Ltd (supra); Okeke v. State (supra). It [final address] is the penultimate part of the three most important portions of the trial period; the first, being the hearing of the evidence; while the last is the judgment, Okeke v. State (2003) LPELR-2436 (SC) 19-20; F-A. Such is its pedestal in the administration of justice that when counsel or a party is denied this right [that is, of address], the trial Court is equally deprived of its enormous benefits. Its inevitable consequence is that a miscarriage of justice has been occasioned. Okafor and Ors v. A.G., Anambra and Ors (1991) LPELR-2414 (SC) 28; A-C; Obodo v. Olomu (1987) 3 NWLR (Pt. 59) 111; Adigun v. A-G of Oyo State (supra). This explains why a party must have the same right as given to his adversary to offer, by his counsel, the final address on the law in support of his case. Ndukauba v. Kolomo and Anor (2005) LPELR-1976 (SC) 12; A-D. It would thus seem obvious that the draftsperson of this section [Section 294] had in mind the eloquent views of a distinguished American Jurist, Dillon, who observed in his Laws and Jurisprudence of England and America that; “I feel reasonably assured of my judgment where I have heard counsel, and a very diminished faith where the case has not been orally argued, for mistakes, errors, fallacies and flaws elude us in Spite of ourselves unless the case is pounded and hammered at the Bar…”
