Courts and Judiciary in Nigeria

Introduction

The Nigerian court system is structured as a hierarchical pyramid with the Supreme Court at its apex. Established under the Constitution of the Federal Republic of Nigeria 1999 (as amended), the judiciary operates as an independent branch of government, exercising judicial powers vested by section 6 of the Constitution. The court system comprises federal courts established by the Constitution and state courts established by state laws, together with specialized appellate courts for customary law and Sharia law. The National Judicial Council (NJC) serves as the central administrative and disciplinary body for the judiciary.

The Supreme Court of Nigeria

The Supreme Court is the highest court in Nigeria, composed of the Chief Justice of Nigeria and not more than 21 justices appointed by the President on the recommendation of the NJC. The court exercises exclusive original jurisdiction in disputes between the Federation and a state, or between states (section 232 of the Constitution). Its appellate jurisdiction extends to appeals from the Court of Appeal as of right in constitutional matters and civil cases involving substantial questions of law, and by leave of the Court of Appeal or the Supreme Court in other cases. Decisions of the Supreme Court are final and binding on all other courts in Nigeria, establishing the doctrine of stare decisis throughout the judicial hierarchy.

The Court of Appeal

The Court of Appeal, headed by the President of the Court of Appeal, hears appeals from the Federal High Court, the High Courts of states, the National Industrial Court, the Sharia Court of Appeal, and the Customary Court of Appeal. Section 240 of the Constitution confers appellate jurisdiction on the Court of Appeal. The court is divided into judicial divisions located across Nigeria’s geopolitical zones. Appeals from the Court of Appeal lie to the Supreme Court as of right in specified cases and by leave in others.

The Federal High Court

The Federal High Court, established under section 249 of the Constitution, exercises jurisdiction over matters specified in the exclusive legislative list, including revenue, customs, admiralty, banking, intellectual property, company law, and federal government actions. The court has one Chief Judge and such number of judges as may be prescribed by an Act of the National Assembly. The Federal High Court also exercises appellate jurisdiction over decisions of the Tax Appeal Tribunal, the Competition and Consumer Protection Tribunal, and other federal administrative tribunals.

State High Courts

Each of Nigeria’s 36 states has a High Court established by the Constitution, presided over by a Chief Judge appointed by the state Governor on the recommendation of the NJC. State High Courts exercise unlimited jurisdiction in civil and criminal matters, subject to the exclusive jurisdiction of the Federal High Court. State High Courts also supervise inferior courts and tribunals within their territorial jurisdiction through the exercise of judicial review powers.

The National Industrial Court

The National Industrial Court (NIC) was elevated to constitutional status by the Third Alteration to the Constitution (2010). The NIC exercises exclusive jurisdiction in labour and employment matters, including trade union disputes, collective bargaining, industrial relations, and employment contracts. Section 254C of the Constitution confers comprehensive jurisdiction on the NIC, and its decisions are appealable to the Court of Appeal.

Sharia Courts of Appeal

Twelve northern states maintain Sharia Courts of Appeal as superior courts of record. The Sharia Court of Appeal exercises appellate jurisdiction over lower Sharia courts in matters of Islamic personal law, including marriage, divorce, inheritance, and family relations. The Grand Kadi presides over each Sharia Court of Appeal. Appeals lie from the Sharia Court of Appeal to the Court of Appeal, which is composed of justices learned in Islamic law.

Customary Courts of Appeal

States with customary law systems maintain Customary Courts of Appeal, presided over by a President of the Customary Court of Appeal. These courts hear appeals from lower customary courts in matters of customary law, particularly those relating to marriage, family property, inheritance, and land tenure governed by native law and custom.

The National Judicial Council (NJC)

The NJC, established under section 153 of the Constitution and detailed in Part I of the Third Schedule, is the central body responsible for the appointment, discipline, and welfare of judicial officers. The NJC recommends candidates for judicial appointment to the President (for federal courts) or state Governors (for state courts). It also investigates complaints against judicial officers and recommends disciplinary action, including removal, to the appropriate appointing authority.

Conclusion

The Nigerian judiciary is a complex, multi-layered institution that reflects the country’s federal structure and legal pluralism. The constitutional independence of the judiciary, safeguarded by the NJC and provisions relating to judicial tenure and financial autonomy, remains fundamental to the rule of law in Nigeria. The hierarchical court system ensures appeals and consistent development of jurisprudence, while specialized courts address the unique demands of Islamic law, customary law, and labour relations.
