The Law is well settled that where a court has no jurisdiction to entertain any claim, anything done in respect of the claim will be an exercise in futility. In the celebrated case on the subject of jurisdiction and competence of court of Madukolu & others v Nkemdilim & others (1962) 2 SCNLR 342; (1962) NSCC 374; (1962) 1 All NLR 587; Bairamian, F.J. stated the law at page 595 as follows:- “Before discussing those portions of the record, I shall make some observations on jurisdiction and the competence of a court. Put it briefly, a court is competent when:- (1) it is properly constituted as regards members and qualification of the members of the bench and no member is disqualified for one reason or another; and (2) the subject matter of the case is within its jurisdiction, and there is no feature of the case which prevents the court from exercising its jurisdiction; and (3) the case comes before the court initiated by due process of law, and upon fulfilment of any condition precedent to the exercise of jurisdiction.” Once there is a defect in competence, it is fatal as the proceedings are a nullity. See Ojo-Ajao & others v Popoola Ajao & others (1986) 5 NWLR (Part 45) 802 and Attorney-General Anambra State v Attorney-General of the Federation (1993) 6 NWLR (Part 302) 692. — Mohammed JSC. AG Kano State v AG Federation (2007) – SC 26/2006
JURISDICTION OF THE COURT IS DETERMINED BY CAUSE OF ACTION
The jurisdiction of the court is determined by the cause of action of the plaintiff as endorsed on the writ of summons or from both the writ of summons and the statement of claim. Where however, an action is commenced by Originating summons then it is the reliefs sought as well as the averments in the affidavit in support of the originating process that would be examined to discern if the court has jurisdiction. These would be relied on if the facts placed before the court as contained in the statement of claim or the affidavit in the case of originating summons are clear and unambiguous to enable it determine the issue. This is because it is the plaintiff who invokes the constitutional right for a determination of his right and accordingly the exercise of the judicial powers of the Constitution vested in the courts.
