In the case of Olafisoye v. FRN (2004) LPELR-2553 (SC), the Supreme Court per Tobi, JSC, held that: “An issue is the question in dispute between the parties necessary for the determination of the Court, see Chief Ejowhomu v. Edok-Eter Mandalis Limited (1986) 5 NWLR (Pt. 39) 1. An issue which is usually raised by way of a question is usually a proposition of law or fact in dispute between the parties, necessary for the determination by the Court; a determination of which will normally affect the result of the appeal. See Adejumo v. Ayantegbe (1989) 3 NWLR (Pt. 110) 417. Issues for determination of appeal, are short questions raised against one or more grounds of appeal and are meant to be a guide to the arguments and submission to be advanced in support of the grounds of appeal. It is a succinct and precise question either of law or of fact for determination by the Court, see Imonikhe v. The Attorney-General of Bendel State (1992) 6 NWLR (Pt. 311) 370. An issue is a disputed point or question to which parties in an action have narrowed their several allegations and upon which they are desirous of obtaining either decision of the Court on question of law, or of the Court on question of fact. See Chief Okoromaka v. Chief Odiri (1995) 7 NWLR (Pt. 408) 411”.
WHEN COURT RAISES AN ISSUE, COURT SHOULD DO WELL TO GIVE PARTY OPPORTUNITY TO ADDRESS IT ON THE ISSUE
But there is nothing in the case of Lawrence Okafor & Ors. v. Felix Nnaife & ors. (1972) 3 E.C.S.L.R. 261, which the learned trial Judge relied upon to support his decision to suggest that the court could take up the point and decide it without hearing the parties. Indeed in that case when the Supreme Court felt that point needed to be taken, their Lordships invited counsel on both sides to address the court on the point, before they decided it. It is basic and fundamental in our system of administration of justice that no one can have a decision entered against him without his being heard. This is the essence of the maxim: audi alterant partem. That maxim implies not only that all the parties to be affected by a decision are entitled to be heard in the case on hand before the decision is given but also that if, in the course of hearing, any new point material to the decision arises, each of such parties shall be heard on it before a decision based upon it can rightly be handed down. Quite apart from this, a Judge who in our system must be and be seen as an impartial umpire will be anything but that if he takes up a material point, no matter how clear it may appear, and, without hearing any of the parties to be affected by the decision, decides it. That cannot be even-handed justice. A court ought never raise an issue for either of the parties and, without hearing both parties proceed to base its judgment on it. See Inua v. Nta (1961) 1 ALL N.L.R. 576; Ejowhomu v. Edok-Eter Ltd. (1986) 5 N. W.L.R. (Pt.39) 1. So, the Court of Appeal was right on that ground.
