Introduction
The concept of jurisdiction is fundamental to the administration of justice in any legal system. It refers to the authority of a court to hear and determine legal disputes and to enforce its judgments. Without jurisdiction, any proceedings conducted by a court, no matter how well-conducted, are a nullity (Madukolu v Nkemdilim, 1962). In Nigeria, the judicial framework and the jurisdiction of its courts are primarily established and defined by the Constitution of the Federal Republic of Nigeria, 1999 (as amended). This essay will provide an overview of the jurisdiction of the superior courts of record in Nigeria. It will examine the constitutional provisions that delineate the powers of the Supreme Court, the Court of Appeal, the Federal High Court, the State High Courts, and other specialised courts, thereby illustrating the hierarchical and functional structure of the Nigerian judiciary.
The Constitutional Basis of Judicial Power and Jurisdiction
Section 6 of the 1999 Constitution vests the judicial powers of the Federation in the courts established for the Federation, and the judicial powers of a State in the courts established for that State. This section lists the superior courts of record, creating a clear hierarchy. Jurisdiction can be classified in several ways, including original jurisdiction (the power to hear a case at first instance), appellate jurisdiction (the power to review decisions of lower courts), and exclusive jurisdiction (the power to hear a matter to the exclusion of all other courts). The constitution carefully allocates these types of jurisdiction among the different courts in the system to ensure a structured and orderly judicial process. The seminal case of Madukolu v Nkemdilim (1962) established that for a court to be competent and have jurisdiction, it must be properly constituted, the subject matter must be within its prescribed scope, and the case must be initiated by due process of law.
The Supreme Court of Nigeria
The Supreme Court stands at the apex of the Nigerian judicial hierarchy. Its composition and jurisdiction are outlined in Sections 230 to 236 of the Constitution. It is the final court of appeal, and its decisions are binding on all other courts in Nigeria.
The Supreme Court possesses both original and appellate jurisdiction. Its original jurisdiction, as detailed in Section 232, is exclusive and pertains to disputes between the Federation and a state, or between states themselves. This role is crucial for resolving constitutional conflicts within Nigeria’s federal structure. For example, a dispute over resource allocation between the federal government and a state government would be heard directly by the Supreme Court.
However, the primary function of the Supreme Court is appellate. Under Section 233 of the Constitution, it hears appeals from the Court of Appeal. An appeal lies as of right in cases involving decisions on questions of law alone in any civil or criminal proceedings, decisions in any civil or criminal proceedings on questions as to the interpretation or application of the Constitution, and decisions concerning fundamental rights. In other matters, appeals can only be brought with the leave of the Court of Appeal or the Supreme Court itself. This filtering mechanism ensures that the Supreme Court is not overburdened and focuses on matters of significant legal and constitutional importance.
The Court of Appeal
Immediately below the Supreme Court is the Court of Appeal. Established by Section 237 of the Constitution, it is principally an intermediate appellate court. Its main function, as provided in Section 240, is to hear and determine appeals from the decisions of the Federal High Court, the High Court of a State, the Sharia Court of Appeal of a State, and the Customary Court of Appeal of a State, among others.
The Court of Appeal’s jurisdiction is almost entirely appellate, covering all final decisions from the lower superior courts and certain interlocutory decisions. Section 241 specifies the instances where an appeal lies as of right, which are extensive and cover most final judgments of a High Court. For other matters, an appeal requires leave.
The Court of Appeal also has a limited original jurisdiction under Section 239 of the Constitution to hear and determine any question as to whether any person has been validly elected to the office of President or Vice-President. This specific grant of original jurisdiction highlights the court's role in adjudicating matters of national political importance, with any appeal from its decision going to the Supreme Court.
The High Courts: A Jurisdictional Divide
A significant feature of the Nigerian judicial system is the division of jurisdiction at the trial level between the Federal High Court and the High Courts of the various states. This division has sometimes been a source of procedural and jurisdictional disputes (Malemi, 2012).
The Federal High Court, established under Section 249, has its jurisdiction specified in Section 251(1) of the Constitution. This jurisdiction is exclusive in relation to a defined list of matters. These matters predominantly concern the revenue, fiscal measures, and administration of the Government of the Federation. They include taxation, customs and excise duties, banking, companies, admiralty, copyright, patents, and trademarks. The rationale is to provide a specialised court to handle matters directly affecting the federal government's economic and administrative interests.
In contrast, the State High Courts, established under Section 270, possess a broad, general jurisdiction. Section 272(1) grants the State High Court jurisdiction to hear and determine any civil proceedings in which the existence or extent of a legal right, power, duty, liability, privilege, interest, obligation, or claim is in issue. It also has jurisdiction over criminal proceedings. Essentially, a State High Court can hear any matter that is not specifically assigned to the Federal High Court or another specialised court. This makes it the primary trial court for a wide range of disputes, including contracts, torts, land matters, and most criminal offences under state law.
Specialised Courts
To address specific types of disputes, the Nigerian legal system incorporates several specialised courts.
The National Industrial Court of Nigeria (NICN) is a key example. The Third Alteration to the 1999 Constitution in 2010 elevated the NICN to the status of a superior court of record and granted it exclusive jurisdiction in civil causes and matters relating to labour, employment, trade unions, industrial relations, and workplace conditions. This has streamlined labour-related litigation, which was previously spread across various High Courts (Ogunye, 2011).
Furthermore, states that have a significant Muslim population may establish a Sharia Court of Appeal, while states with a body of customary law may establish a Customary Court of Appeal. As per Sections 277 and 282 of the Constitution, these courts exercise appellate and supervisory jurisdiction in civil proceedings involving questions of Islamic personal law and customary law, respectively, on appeal from lower courts. Their jurisdiction is specialised and confined to these specific areas of personal law.
Conclusion
The jurisdiction of courts in Nigeria is meticulously structured by the 1999 Constitution, creating a clear judicial hierarchy with defined roles for each court. The Supreme Court serves as the final arbiter, the Court of Appeal acts as the main appellate filter, and a division of labour exists at the trial level between the specialised, exclusive jurisdiction of the Federal High Court and the broad, general jurisdiction of the State High Courts. Specialised courts like the National Industrial Court further refine this structure by providing expert forums for specific legal areas. While this constitutional framework provides a comprehensive system for the administration of justice, the precise boundaries of jurisdiction, particularly between the Federal and State High Courts, can sometimes lead to uncertainty and litigation. Nevertheless, the system is designed to ensure that all legal grievances have a judicial forum for determination, from the grassroots level to the highest court in the land.
