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”.
A PARTY CANNOT CANVASS ARGUMENT OUTSIDE OF ISSUES FRAMED
It is clear that both issues are confined to the competence of the plaintiffs/respondents to sue in the matter. As they do not extend to the competence of the defendants/appellants to defend the action, I shall not go there. This is because parties are, bound by the issues formulated in their briefs. In other words, a party cannot advance an argument outside the issue or issues formulated in the brief without leave of Court. This stems from the larger ambit of our adjectival law that parties are, bound by their briefs.
