SUBSTANTIVE VERSUS PROCEDURAL JURISDICTION OF THE COURT

In Adekanola v. A.P.D. Co. Ltd. (2026) 9 NWLR (Pt. 2048) 309 at 354–355, E–D per Tsammani JSC:

‘It should also be noted that, jurisdiction consists of procedural (adjectival) and substantive jurisdiction. Procedural (Adjectival) jurisdiction regulates the enforcement of substantive law. It comprises the rules by which a court hears or conducts civil or criminal proceedings. Substantive jurisdiction (or law) defines the rights and obligations of the parties in controversy. The substantive jurisdiction or law, determines the cause of action in a particular case. See Prince J.S. Atolagbe & Anor v. Alhaji Ahmadu Awuni& Ors (1997) LPELR-593 (SC), (1997) 9 NWLR (Pt. 522) 536; Central Bank of Nigeria v. Inalegwu Frankline Ochife & Ors (2025) LPELR-80220 (SC), (2025) 12 NWLR (Pt. 2000) 1 and Total Exploration & Production Nigeria Ltd v. Okwu (2024) LPELR-62623 (SC), (2024) 17 NWLR (Pt. 1967) 379. Thus, breach of substantive law or jurisdiction will have the effect of nullifying any judgment or order reached in the absence of such jurisdiction. In the case of Mobil Producing Nigeria Unlimited v. Lagos State Environmental Protection Agency & Ors (2002) LPELR-1887(SC), (2002) 18 NWLR (Pt. 798) 1 this court held thus: “……. sometimes, the distinction between substance and procedure is blurred. It is generally accepted that matters (including facts which define the rights and obligations of the parties in controversy) are matters of substance defined by substantive law, whereas matters which are mere vehicles which assist the court or Tribunal in going into matters in controversy or litigated before it are matters of procedure regulated by procedural law. Facts which constitute the cause of action are matters of substance and should be pleaded, whereas facts which relate to how a party is to invoke the jurisdiction of the court for a remedy pursuant to his cause of action is a matter of procedure outside the realms of pleadings ……”

As stated earlier in the course of this judgment matters of substantive law or jurisdiction are donated either by the Constitution or Statute. In the instant case, we are confined to the substantive jurisdiction of the trial court, which is the Federal High Court of Nigeria. It is axiomatic that the jurisdiction of the Federal High Court is defined by section 251 of the Constitution of the Federal Republic of Nigeria, 1999 (as altered).’

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.

SITUATIONS WHERE ISSUE OF JURISDICTION MAY BE RAISED

Any objection to the jurisdiction of a court can be raised in any of the following situations – a. On the basis of the statement of claim, b. On the basis of evidence received, c. By motion supported by affidavit setting out facts relied on, d. On the face of writ of summons. Where appropriate as to the capacity in which the action was brought or against whom the action was brought.

WHEN CAN IT BE SAID THAT A COURT HAS JURISDICTION TO HEAR A CASE

It is now settled law that jurisdiction is the life blood of adjudication in that any decision by a Court that lacks jurisdiction to hear and determine a matter is a nullity no matter how well conducted see Madukolu vs Nkemdilim 1962 NSCC 374 at 379-380. When can it be said that a Court has jurisdiction to hear and determine a case? As stated earlier, the Supreme Court in the above cited case decided that for a Court to have the requisite jurisdiction to hear a matter: (a) the Court must be properly constituted as regard numbers and qualifications of members of the bench, and no member is disqualified for one reason or another; (b) the subject matter of the case is within the jurisdiction of the Court and there is no feature in the case that prevents the Court from exercising its jurisdiction; and (c) the case comes before the Court initiated by due process of the law, and upon fulfilment of any condition precedent to the exercise of jurisdiction.
