Per Oputa, JSC. in Chief Gani Fawehinmi v Nigerian Bar Association & ors. (No.2) (1989) 2 N.W.L.R. (Pt.105) 558 at page 650. “Our law is the law of the practitioner rather than the law of the philosopher. Decisions have drawn their inspiration and their strength from the very facts which framed the issues for decision. Once made, these decisions control future judgments of the Courts in like or similar cases. The facts of two cases must either be the same or at least similar before the decision in the earlier case can be used in a later case, and even there, merely as a guide – What the earlier decision establishes is only a principle, not a rule. Rules operate in an all or nothing dimension. Principles do not. They merely incline decisions one way or the other. They form a principium or a starting point. Where one ultimately lands from that starting point will largely depend on the peculiar facts and circumstances of the case in hand.”
STARE DECISIS MAKES THE LAW CERTAIN
It is a policy of Courts to stand by established precedent for the certainty of the law. Agreed, no two cases have identical facts. Where, however, the facts of the decided case are substantially the same with the case at hand, the principle of stare decisis enjoins a Court to follow the earlier judicial decisions when the same points arose again in litigation. It is also a rule of law that ensures certainty in the state of the law and its application.
