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
NATURE OF JURISDICTION OF COURTS
Jurisdiction is to a Court what a door is to a house. The question of a Courts jurisdiction is called a threshold issue because it is at the threshold of the temple of justice. Jurisdiction is a radical and fundamental question of competence, for if the Court has no jurisdiction to hear the case, the proceedings are and remain a nullity, however well conducted and brilliantly decided they might have been. A defect in competence is not intrinsic but rather extrinsic to adjudication. Oloba v. Akereja (1988)3 NWLR (Pt.84)508; Oloriode v. Oyebi (1984) 1 SCNLR 390; Ezomo v. Oyakhire (1985) 1 NWLR (Pt. 2) 105; Petrojessica Ent. Ltd. v. Leventis Technical Co. Ltd. (1992) 5 NWLR (Pt. 244) 675; Barclays Bank v. C.B.N. (1976) 6 SC 175; African Newspapers (Nig.) Ltd. v. F.R.N. (1985) 2 NWLR (Pt. 1006) 608; A.-G., Anambra State V. A.-G., Fed. (1993) 6 NWLR (Pt. 302) 692; Saleh v. Monguno (2003) 1 NWLR (Pt. 801) 221. (The underlining is supplied by us for emphasis). Under the Nigerian legal system, Courts are creations or creatures of statutes or legislations such as the grundnorm itself, that is, the Constitution or Decrees or Acts or Laws or Edicts. Hence, it is the legislations themselves that cloak the Courts with powers or adjudicatory jurisdiction. Therefore, if the Constitution, Decrees, Acts, Laws and Edicts do not grant jurisdiction to a Court, the Court itself and or parties cannot by agreement endow the Court with jurisdiction. For once there is a defect in the competence of a Court to adjudicate upon an action, the proceedings in the action no matter how otherwise so well, properly and brilliantly conducted would amount to a nullity and an exercise in futility. Therefore, since Courts are creatures of statutes, their jurisdiction is confined, limited, restricted and circumscribed by the statutes creating them. Moreover, a Court must study the statute which creates it and must not misconstrue same to exercise jurisdiction not donated to it thereby. See also the cases of: (1) Ndaeyo v. Ogunnaya (1977) 1 SC p. 11; (2) National Bank of Nigeria v. Shoyoye (1977) 5 SC p. 181 and (3) A.-G., Fed. v. Guardian Newspapers Ltd. (1999) 9 NWLR (Pt. 618) p. 187.
