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.
