The Nigerian legal system is a complex and fascinating tapestry woven from various historical, cultural, and political threads.
As the most populous nation in Africa, Nigeria operates a "pluralistic" legal system, meaning that multiple systems of law function side-by-side.
This complexity arises from the country’s colonial history under British rule, its rich indigenous traditions, and its religious diversity.
Understanding the primary sources of Nigerian law is essential for legal practitioners, law students, and the general public.
These sources provide the authority upon which legal rules are established, interpreted, and enforced.
Without a clear understanding of these sources, one cannot navigate the Nigerian courtroom or understand the rights and obligations of citizens.
In this comprehensive guide, we will delve into the primary sources that form the bedrock of the Nigerian legal framework, ranging from the Constitution to the intricacies of Customary law.
1. The Constitution of the Federal Republic of Nigeria
The Constitution is the most significant source of law in Nigeria.
Often referred to as the "Grundnorm" (a term popularized by jurist Hans Kelsen), it is the supreme law of the land.
The current working document is the 1999 Constitution (as amended).
The Supremacy of the Constitution
Section 1(1) of the 1999 Constitution explicitly states that the Constitution is supreme and its provisions shall have binding force on all authorities and persons throughout the Federal Republic of Nigeria.
Furthermore, Section 1(3) provides a "consistency test": if any other law is inconsistent with the provisions of the Constitution, the Constitution shall prevail, and that other law shall, to the extent of the inconsistency, be void.
What the Constitution Covers
The Constitution provides the framework for governance in Nigeria. It outlines:
The structure of the Federal Government (Executive, Legislature, and Judiciary).
The division of powers between the Federal and State governments (Exclusive, Concurrent, and Residual lists).
The fundamental human rights of citizens (Chapter IV).
The qualifications for political offices and the conduct of elections.
The establishment of the Nigerian Police Force and Armed Forces.
Because it dictates how all other laws are made and validated, the Constitution sits at the very apex of the hierarchy of Nigerian laws.
2. Nigerian Legislation (Statutory Law)
Legislation refers to laws enacted by the legislative arm of government specifically for the purpose of governance.
In Nigeria, legislation is a primary source of law that has seen significant growth since independence in 1960.
Federal Legislation: Acts of the National Assembly
The National Assembly, consisting of the Senate and the House of Representatives, has the power to make laws for the peace, order, and good government of the Federation.
Laws passed by the National Assembly are called "Acts.
" Examples include the Companies and Allied Matters Act (CAMA) and the Criminal Code Act.
State Legislation: Laws of the House of Assembly
Each of the 36 states in Nigeria has its own House of Assembly.
Laws passed at the state level are referred to as "Laws.
" These laws cover matters within the state's jurisdiction, such as land use (within the state), local government administration, and state-specific taxes.
Subsidiary Legislation (Delegated Legislation)
Often, the legislature delegates the power to make specific rules to administrative bodies or ministers.
These are known as subsidiary legislations, statutory instruments, or bylaws.
While they are not passed directly by the legislature, they derive their authority from a "parent" Act or Law and carry the full force of law unless they exceed the powers granted by the parent statute (the doctrine of ultra vires).
Military Decrees and Edicts
During Nigeria's history of military rule, the legislative process was suspended.
The Federal Military Government made laws through "Decrees," while State Military Governors issued "Edicts.
" While Nigeria is currently under democratic rule, many of these Decrees were converted into Acts and remain part of the Laws of the Federation of Nigeria (LFN) today.
3. Received English Law
Due to Nigeria’s history as a British colony, English law serves as a foundational pillar of the Nigerian legal system.
Through various "Reception Clauses" in Nigerian statutes, certain aspects of English law were formally "received" into the Nigerian legal framework.
Received English Law consists of three main components:
The Common Law
Common law refers to the body of law developed by judges through decisions of courts and similar tribunals (judicial precedents), rather than through legislative statutes.
In Nigeria, common law principles govern areas such as contracts, torts, and certain aspects of property law where local statutes may be silent.
The Doctrines of Equity
Equity was developed in England to mitigate the harshness and rigidity of the Common Law.
It introduced concepts of fairness and justice.
Maxims such as "Equity follows the law" and "He who comes to equity must come with clean hands" are frequently cited in Nigerian courts today.
Where there is a conflict between Common Law and Equity, Equity prevails.
Statutes of General Application (SOGA)
These are statutes that were in force in England on or before January 1, 1900.
Under the reception clauses, these laws apply in Nigeria unless they have been repealed or replaced by local Nigerian legislation.
Examples include the Wills Act of 1837 and the Conveyancing Act of 1881.
It is important to note that many states (especially in the old Western Region) have since repealed these and enacted their own local versions.
4. Judicial Precedent (Case Law)
Judicial precedent, also known as stare decisis ("let the decision stand"), is the principle where lower courts are bound by the decisions of higher courts on similar facts and legal issues.
This ensures consistency, certainty, and predictability in the law.
The Hierarchy of Nigerian Courts
The application of judicial precedent follows the hierarchy of the Nigerian judiciary:
The Supreme Court of Nigeria: The highest court.
Its decisions are final and binding on all other courts in Nigeria.
The Court of Appeal: Bound by the decisions of the Supreme Court, and its decisions bind all courts below it.
The Federal High Court and State High Courts: These are courts of coordinate jurisdiction.
They are bound by the Supreme Court and Court of Appeal.
Magistrate Courts, Customary Courts, and Sharia Courts: These are lower courts that must follow the precedents set by the superior courts of record.
Ratio Decidendi and Obiter Dictum
In a judgment, only the Ratio Decidendi (the legal reason for the decision) is binding as a precedent.
An Obiter Dictum (something said "by the way") is a comment made by a judge that is not essential to the decision.
While obiter dicta are not binding, they can be highly persuasive in future cases.
5. Customary Law
Before the arrival of the British, various ethnic groups in Nigeria had their own systems of law.
Customary law remains a vital source of law, particularly in matters of marriage, inheritance, land ownership, and traditional leadership.
Characteristics of Customary Law
Customary law in Nigeria is generally:
Unwritten: Traditionally passed down through oral tradition, though many customs are now documented in textbooks and judicial decisions.
Pluralistic: It varies from one ethnic group to another (e.
g.
, Igbo customary law differs from Yoruba customary law).
Flexible: It changes over time to reflect the current social realities of the community.
The Validity Tests
For a custom to be enforced by a Nigerian court, it must pass three rigorous "validity tests":
The Repugnancy Test: The custom must not be repugnant to natural justice, equity, and good conscience.
(For example, customs involving human sacrifice or the killing of twins were struck down under this test).
The Incompatibility Test: The custom must not be incompatible with any existing legislation or the Constitution.
The Public Policy Test: The custom must not be contrary to public policy or detrimental to the state.
6. Islamic Law (Sharia)
Islamic law, or Sharia, is a significant source of law, particularly in Northern Nigeria.
It is not considered "customary law" in the strict sense but is often categorized alongside it in legal discussions regarding personal law.
Sources and Application
Sharia is derived from the Holy Quran, the Sunnah (practices of the Prophet Muhammad), the Ijma (consensus of scholars), and Qiyas (analogical reasoning).
In Nigeria, Sharia primarily applies to civil matters involving Muslims who choose to be governed by it, such as marriage (Nikah), divorce, and succession.
In several Northern states, Sharia has also been extended to cover criminal law, although this remains a subject of significant constitutional debate regarding its alignment with the fundamental rights guaranteed by the 1999 Constitution.
7. International Law (Treaties)
In an increasingly globalized world, international law has become a primary source of Nigerian law.
Nigeria is a member of various international organizations, including the United Nations, the African Union, and ECOWAS.
The Domestication Requirement
Nigeria follows a "dualist" approach to international law.
According to Section 12 of the 1999 Constitution, no treaty entered into by Nigeria shall have the force of law until it has been enacted into law by the National Assembly.
This process is called "domestication.
"
A famous example is the African Charter on Human and Peoples' Rights.
Because it was domesticated by the Nigerian government, it can be directly enforced in Nigerian courts, sometimes providing wider protections than the Constitution itself.
Conclusion
The primary sources of Nigerian law—the Constitution, Legislation, Received English Law, Judicial Precedent, Customary Law, Islamic Law, and International Treaties—collectively form a robust and dynamic legal environment.
While the Constitution remains the ultimate authority, the interaction between these various sources allows the Nigerian legal system to address the needs of a diverse and evolving society.
For anyone dealing with legal issues in Nigeria, it is crucial to recognize which source of law takes precedence in a given situation.
Whether you are a business owner navigating statutory regulations, a family member dealing with customary inheritance, or a lawyer arguing a case based on judicial precedent, understanding these foundations is the first step toward achieving justice and legal clarity in the "Giant of Africa.
