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 COURT CANNOT BE GIVEN BY RULES OF COURT
The law is settled that the jurisdiction of a Court of record, in its broad and substantive sense, cannot be conferred by the Rules of Court. The Rules of Court are only made, pursuant to the powers conferred on the heads of Courts by the Constitution to make Rules, to regulate practice and procedure in their respective Courts. The Rules they make are only to regulate the practice and procedure in their respective Courts. The Rules do not confer jurisdiction on the Court to entertain causes or matters. Rather, the jurisdiction of Courts in Nigeria is either conferred or vested by the Constitution or the enabling statute establishing the Court.
