Introduction
Jurisdiction remains the foundation of every adjudicatory process. Without it, proceedings—however diligently conducted—are a nullity. This principle explains the settled position that parties may raise jurisdiction at any stage of proceedings, even for the first time on appeal, and that a court may raise it sua sponte.[1]
However, this principle is not without limits. Once a competent court—whether at trial or on appeal—has expressly considered and determined a specific jurisdictional issue, parties cannot reopen or re-argue that issue as a fresh ground in subsequent appeals, even before the apex court, the Supreme Court of Nigeria.
This article examines this important qualification, drawing on Nigerian judicial authorities to demonstrate why the rule promotes certainty, procedural efficiency, and finality in litigation.
Jurisdiction: The Unshakeable Foundation
The general rule is well settled and frequently cited. The Supreme Court of Nigeria, in the locus classicus case of Madukolu v Nkemdilim,[2] laid down the essential conditions for the competence of a court, emphatically holding that where a court lacks competence, its proceedings—no matter how well conducted—are a nullity. This principle explains why parties may object to jurisdiction at any stage of proceedings, whether at trial, on appeal, or by the court sua sponte. Jurisdiction is a threshold issue that goes to the very root of a court’s authority to adjudicate.
The rationale is straightforward: where a court lacks jurisdiction, it lacks the power to act. Permitting such a court to proceed would amount to an exercise in futility, wasting judicial time and resources and inevitably producing a void judgment.
The Crucial Limitation: When “Anytime” Becomes “Not Anymore”
Although the right to challenge jurisdiction remains fundamental, it is necessary to distinguish between raising a jurisdictional issue for the first time and attempting to re-litigate one that a competent court has already determined.[3] Nigerian courts do not permit the latter.
The right to raise jurisdiction at any stage does not confer an unfettered licence to repeatedly resurrect issues that parties have fully canvassed and that a court has conclusively resolved. Any attempt to do so constitutes an abuse of court process.[4]
The Rationale: Beyond Repetitive Litigation
Nigerian courts, particularly the Supreme Court, have consistently emphasised the need for finality in litigation and the prevention of abuse of process.[5] Several interrelated principles support this limitation:
- Prevention of Abuse of Court Process:
An abuse of court process arises where a party improperly uses the judicial process to harass, annoy, or delay proceedings, or to impose unnecessary expense on the opposing party or the court. Re-litigating a jurisdictional issue already determined by a competent court clearly falls within this category. It reflects a misuse of judicial resources and a disregard for the conclusiveness of judicial pronouncements. As the Supreme Court held in Saraki v. Kotoye, courts possess inherent jurisdiction to prevent the abuse of their process.
- Judicial Economy and Efficiency:
Judicial resources are finite. Permitting parties to repeatedly raise jurisdictional arguments that courts have already resolved would create endless litigation, congest court dockets, and undermine the efficient administration of justice. Anthony Nnaemeka Aniagolu JSC succinctly captured this rationale in Aro v. Fabolude,[6] where his Lordship stated: “There must be an end to litigation.”
- Sanctity and Finality of Judicial Decisions:
Respect for judicial decisions remains a cornerstone of any legal system. Once a court determines an issue, that decision is, as between the parties, binding and conclusive. Although doctrines such as res judicata and issue estoppel do not strictly apply at the stage of raising jurisdiction for the first time, they become relevant once a competent court has conclusively determined the issue. Allowing parties to re-argue such issues would undermine the authority and finality of judicial decisions.
Nigerian Precedents: Guiding Principles
The Supreme Court of Nigeria has consistently rejected attempts to re-litigate jurisdictional issues [7] that a competent court has already determined. Once parties have raised, argued, and obtained a judicial decision on a specific jurisdictional point, the principle of res judicata operates to preclude its re-litigation. This position differs from a proper appeal against that decision on jurisdiction, which invites a higher court to review the correctness of the earlier determination. Appellate courts entertain such challenges only within the confines of a valid appeal, not through a fresh re-argument of settled issues.
In Oyeyemi v Owoeye,[8] the Supreme Court reaffirmed that once a competent court has determined an issue, parties cannot re-open or re-litigate it in the same or subsequent proceedings unless an appellate court sets the decision aside. Although the case addresses general issues, the principle applies with equal force to jurisdictional questions that have received prior judicial determination.
These authorities demonstrate that courts carefully distinguish between a legitimate jurisdictional objection and an attempt to frustrate proceedings by repeatedly raising settled issues.
Practical Implications for Counsel
For legal practitioners, this principle underscores the need for diligence and strategic precision at every stage of litigation:
- Thoroughness at First Instance:
Counsel must identify, investigate, and present any jurisdictional objection comprehensively at the trial stage.
- Precision in Appeals:
Where a jurisdictional ruling forms part of the decision, counsel must challenge it through properly framed grounds of appeal. The appeal must address the lower court’s reasoning and findings, not merely restate the original objection as though it were a fresh issue.
Failure to comply with this principle may result in the dismissal of an appeal, the striking out of processes, or the award of costs for abuse of court process.
Conclusion
The principle that parties cannot re-argue jurisdiction on appeal once a competent court has conclusively determined it strikes a necessary balance. It preserves the fundamental importance of jurisdiction while upholding the equally critical principles of judicial efficiency, finality of litigation, and the prevention of abuse of court process.
Although jurisdiction remains the foundation of judicial authority, litigation must come to an end. Nigerian jurisprudence, guided by the Supreme Court of Nigeria, ensures that courts remain open to legitimate jurisdictional challenges but firmly reject attempts to endlessly re-argue issues already decided. This approach safeguards both the integrity and effectiveness of the legal system.
