In Clement C. Ebokam vs. Ekwenibe & Sons Trading Company Ltd. (1999) 7 SCNJ 77, Kalgo, JSC held at page 87 that: “…Where the decisions of the Court under consideration clearly and wholly disposes of all the rights of the parties in the case, that decision is final. But where the decision only disposes of an issue or issues in the case, leaving the parties to go back to claim other rights in the Court, then that decision is interlocutory. And in order to determine whether the decision is final or interlocutory, the decision must relate to the subject matter in dispute between the parties and not the function of the Court making the order.”
A COURT HAS INHERENT POWERS TO SET ASIDE ITS OWN ORDER MADE WITHOUT
In sum, I hold firmly that where a judgment of this court or an order thereof is adjudged a nullity, a party affected thereby is entitled to have it set aside ex debito justitiae. The court has inherent jurisdiction or power to set aside its own order or decision made without jurisdiction if such order or decision is in fact a nullity or was obtained by fraud or if the court was misled into granting same by concealing some vital information or facts.
