The British legal system has left an enduring imprint on Nigeria. Introduced during colonial rule, it created a hybrid legal framework that blended English common law, equity principles, statutory law, and indigenous customary systems. Islamic law was preserved in Muslim-majority areas under indirect rule. This legal pluralism continues to shape Nigeria’s judicial structure, constitutional arrangements, and debates about the harmonisation of diverse legal traditions.
Pre-Colonial Legal Systems
Before British colonisation, Nigeria’s peoples had diverse legal traditions suited to their cultural contexts. Among the Yoruba in the south-west, law was administered by kings (Obas) and councils of elders. Disputes often involved communal consultation, emphasising restorative justice rather than punitive sanctions. The Igbo in the south-east relied on village assemblies and age-grade groups, with customary laws transmitted orally. In the north, Islamic emirates, influenced by centuries of Islamic jurisprudence, administered Sharia law for both civil and criminal matters, alongside customary norms.
These indigenous systems were grounded in cultural legitimacy rather than formal codification.
Colonial Legal Transplantation
The British formalised their legal influence following the annexation of Lagos in 1861. The Supreme Court Ordinance of 1876 established a structured judiciary in Lagos Colony and codified the application of English law. This process intensified after the amalgamation of Northern and Southern Nigeria in 1914 under Lord Frederick Lugard.

Lugard adopted indirect rule, allowing indigenous legal systems to operate alongside British law. This created a pluralistic arrangement:
- English law governed commercial matters and cases involving Europeans.
- Customary law applied to local communities, administered in native courts.
- Islamic law governed personal status issues in Muslim-majority areas, administered by Sharia courts.
The 1914 legal system entrenched this hybrid model, which persists today.
Key Figures in Nigerian Legal Development
- Justice Chukwudifu Oputa (1916–2014): Served on the Supreme Court and championed integrating customary law with modern jurisprudence.
- Dr Nnamdi Azikiwe (1904–1996): Nigeria’s first president, who advocated for constitutional self-rule and legal reforms during the independence movement.
- Chief Frederick Rotimi Williams (1920–2005): The first Nigerian called to the Bar, influential in shaping Nigeria’s legal profession.
These figures helped indigenise Nigeria’s legal system while preserving British legal heritage.
Constitutional Evolution
1960 Independence Constitution established a Westminster-style system with a federal structure, independent judiciary, and protection of fundamental rights. It recognised customary and Islamic law in matters of personal status.
1963 Republican Constitution retained this framework but introduced a republic system. Later constitutions (1979, 1999) maintained the British legal influence while adapting to Nigeria’s federal realities and socio-political challenges.
Court Structure and Legal Procedure
Nigeria’s court hierarchy mirrors the British system: Supreme Court → Court of Appeal → Federal High Court → State High Courts → Magistrates and Customary Courts. The adversarial system, principles of evidence, and doctrines such as stare decisis are inherited British legacies.
The Legal Practitioners Act governs legal practice, and the Nigerian Law School trains all lawyers, modelled closely on British legal education.
Integration of Indigenous Law
Customary Law: The colonial administration codified many customary laws, often distorting them by translating oral traditions into rigid forms. The “repugnancy test” requires customary law to align with natural justice and equity to be enforceable.
Sharia Law: Recognised in the north, Sharia applies in personal status matters and, in some states, extends to criminal cases. This dual system creates ongoing challenges in harmonising national law with religious law.
Contemporary Legal Challenges
Nigeria’s legal system continues to grapple with:
- Balancing inherited British procedures with local realities.
- Access to justice amid complexity and cost.
- Clarifying the scope of customary and Sharia law within a unified legal system.
- Adapting legal education to modern needs.
Recent reforms include specialised commercial courts, electronic filing systems, and increased reliance on alternative dispute resolution.

Author’s Note
The British legal legacy in Nigeria is a profound but contested inheritance. It established formal legal structures and the rule of law but also introduced challenges of pluralism, access, and harmonisation with indigenous traditions. Nigeria’s legal evolution reflects the continuing negotiation between colonial inheritance and contemporary needs. The challenge today is to preserve the strengths of the British system, judicial independence, rule of law, and procedural fairness, while making it accessible, culturally relevant, and adapted to Nigeria’s democratic aspirations.
