Customary Law in Nigeria
Introduction
Customary law is a fundamental component of Nigeria’s plural legal system, comprising the customs, traditions, and practices of the diverse ethnic communities that constitute the Nigerian state. Customary law predates colonial rule and continues to govern significant aspects of life for many Nigerians, particularly in matters of personal status, family relations, land tenure, and community governance. The Constitution and statutes recognize customary law as a source of law, subject to certain validity tests. The courts play a crucial role in ascertaining, applying, and developing customary law.
Nature and Sources
Customary law derives from the social practices of communities that have acquired the force of law through long usage and acceptance. It is unwritten, flexible, and dynamic, adapting to changing social conditions. The sources of customary law include:
- Community customs and traditions
- Decisions of customary courts and traditional rulers
- Expert opinions of chiefs and elders
- Judicial decisions of Nigerian courts recognizing and applying customary law
- Writings of legal scholars and anthropologists
Ascertainment of Customary Law
The ascertainment of customary law presents unique challenges for the courts. Unlike English law, customary law is not recorded in statutes or law reports. The Evidence Act 2011, section 16, provides that a custom may be proved by evidence of persons with special knowledge of the custom. The court may also take judicial notice of customs that have been frequently proved in court.
The Supreme Court in Oyewunmi v Ogunesan (1990) 3 NWLR (Pt 137) 182 held that a party seeking to rely on customary law must lead evidence to prove the custom, unless the court can take judicial notice of it. The court may also refer the matter to customary law experts or to the customary court for a ruling on the applicable custom.
Validity Tests
Customary law is subject to three validity tests:
The Repugnancy Test
A customary rule is unenforceable if it is repugnant to natural justice, equity, and good conscience. The repugnancy doctrine has been applied to invalidate customs that discriminate on the basis of gender, deny inheritance rights to widows, or impose cruel or oppressive obligations.
The Incompatibility Test
A customary rule is invalid if it is incompatible with any legislation in force in Nigeria. Statutory provisions prevail over inconsistent customary law.
The Public Policy Test
A customary rule is unenforceable if it is contrary to public policy. The courts have applied this test to invalidate customs that undermine the administration of justice or violate fundamental values.
Areas of Application
Customary law governs a range of matters, primarily in the realm of personal law:
- Marriage: Customary marriage is recognized as valid under Nigerian law
- Divorce: Customary grounds for divorce are recognized
- Inheritance: Customary rules of succession govern the distribution of property on death
- Land Tenure: Customary land tenure systems govern land ownership and use
- Family Relations: Custody, maintenance, and family property are governed by custom
- Dispute Resolution: Customary arbitration and mediation are recognized mechanisms
Customary Courts
Customary courts exist in various states to adjudicate matters governed by customary law. These courts are established by state laws and exercise jurisdiction primarily over civil matters involving customary law. Appeals from customary courts lie to the Customary Court of Appeal of the state and then to the Court of Appeal.
Interaction with Other Legal Systems
Customary law interacts with English law and Sharia law in the Nigerian legal system. Choice of law rules determine which legal system applies in particular cases. In matters of personal status, the law of the parties (whether customary or Islamic) generally governs. The courts seek to harmonize the application of different legal systems within the framework of the Constitution and the rule of law.
Conclusion
Customary law is a vital and dynamic component of the Nigerian legal system, providing legal rules and institutions that reflect the values and traditions of Nigeria’s diverse communities. The courts play a crucial role in ascertaining and applying customary law while ensuring that it conforms to fundamental constitutional values. The continued vitality of customary law demonstrates the resilience and adaptability of indigenous legal traditions within the modern Nigerian state.
