In Obodo v. Olomu (1987) 3 NWLR (Pt.59) 111 at page 121, Belgore, JSC, observed as follows: “Addresses of counsel form part of the case and failure to hear the address of one party, however overwhelming the evidence on the one side, vitiates the trial because in many cases, it is after the addresses that one finds the law on the issue fought not in favour of the evidence adduced … By holding that the decision could not have been different if all the address were before the trial court, the Court of Appeal was attempting to read the mind of the trial Judge. He heard the evidence and saw the witnesses, the addresses might have thrown a new light on his view on the evidence. For a totality of a case heard entails not only the evidence but also the addresses.” At pages 123 and124, Obaseki, JSC, stated:- “The hearing of addresses by every court established by the Constitution of the Federal Republic of Nigeria is recognised by the constitution. It is to be given before judgment. See section 258 (1) – “Its beneficial effect and impact on the merit of the case is enormous and unquantifiable. The value is immense and its assistance to the Judge in arriving at just and proper decision though dependent on the quality of the address cannot be denied … until the learned trial Judge’s mind is exposed to an address, no one can say what effect it will have on his mind. It cannot be said that in the light of the above, the failure to hear the address of counsel for the plaintiff has not occasioned a miscarriage of justice. It certainly has not served the interest of justice. Miscarriage of justice vitiates a judgment and renders it a nullity.”
THE RIGHT TO FINAL ADDRESS IS PROTECTED BY THE CONSTITUTION
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…”
