In the case of AG of Lagos State Vs. AG FEDERATION (2004) LPELR – SC 70/2004, this Court aptly postulated: What is legal right? A legal right in my view, is a right recognisable in law. It means a right recognised by law and capable of being enforced by the plaintiff. It is a right of a party recognised and protected by a rule of law, the violation of which would be a legal wrong done to the interest of the plaintiff; even though no action is taken. The determination of the existence of a legal right is not whether the action will succeed at the trial but whether the action denotes such a right by reference to the enabling law in respect of the commencement of the action. Per Niki Tobi, JSC @ 97-98 paragraphs G — B.
CHANGE IN LAW DOES NOT NULLIFY RIGHTS BASED ON THE OLD LAW
When the Supreme Court departs from its earlier decision on a point, the departure does not operate to generally overrule and nullify all previous decisions that followed the earlier decision it has departed from. The departure serves to chart a new direction to be followed without affecting the previous status quo. If the new decision is one on procedure including venue, pending and new cases at all levels will now be decided in accordance with the new decision. If the new decision applies the law on the existence of rights, interests and obligations differently, new and pending cases will be decided according to it depending on when the cause action arose or when the right, interest or obligation came into being. The general principle of law is that a change in law does not result in the nullification of rights and interests based on the previous law. That is why amending or repealing legislations provide for the saving of such rights and interests including ongoing situations that originated on the basis of the old law. On the basis of this general principle, it is the law prevailing at the time the right or interest accrued or at the time a situation arose and not the new law that determines its validity. In the light of the foregoing, I hold that the Learned respondent’s counsel reliance on the principle of ex nihilo nihil fit as espoused by the Legendary Lord Denning in MACFOY v. UAC (1962) AC, has no basis here.
