Pats-Acholonu, JSC in N.I.M.B. LTD vs. U.B.N. LTD (2004) 12 NWLR (pt. 888) 599 at 618 thus: “Now there is no doubt that the two Courts in this case of co-ordinate jurisdiction became seised of the same subject matter in which it must be made absolutely clear, made orders which from whatever or however any one may look and try to synthesise or analyse them, were pitched against each other. In that case, the protagonists, id est, the legal combatants would inevitably be put in the quandary as to which order would prevail or be obeyed. …They ought necessarily to avoid a situation where the Court by its being less cautious exposes itself by the nature of the order it makes to ridicule and the majesty and aura of its pronouncements are either compromised or treated with ignominy as a non-issue by the confused parties and I dare say by the common citizenry.”
The law is settled that a decision of a Court of competent jurisdiction not appealed against remains valid, subsisting and binding on the parties and is presumed acceptable by them. It is also the law that where there is an appeal on some points only in a decision, the appeal stands or falls on those points appealed against only while the other points or decisions not appealed against remain valid, subsisting and unchallenged.
