The legal landscape in Nigeria is rich and diverse, influenced by a combination of customary, statutory, and case law. Within this intricate tapestry, the Doctrine of Covering the Field stands out as a fundamental legal principle that shapes the relationship between federal and state laws. This doctrine, also known as the Doctrine of Occupied Field, plays a crucial role in determining the extent to which federal and state legislatures can enact laws on the same subject matter.
Understanding the Doctrine of Covering the Field
The Doctrine of Covering the Field is rooted in the constitutional division of powers between the federal and state governments in Nigeria. According to the Nigerian Constitution of 1999 (as amended), legislative powers are allocated between the National Assembly (federal) and State Houses of Assembly (state). The doctrine essentially asserts that when the National Assembly has enacted legislation on a particular subject matter, to the exclusion of any other law, the field becomes “covered,” and states are precluded from legislating on the same subject.

The Doctrine in Practice
To comprehend the practical implications of the Doctrine of Covering the Field, one must delve into specific examples and case law. Courts in Nigeria have grappled with cases where the question arises as to whether a particular subject matter falls within the exclusive legislative list of the National Assembly. Notable areas include aviation, immigration, and telecommunications, among others.
Conflict arising between state legislation and federal legislature on a matter within the concurrent legislative list initiates a potential clash for legal supremacy. This necessitated the inclusion of a constitutional provision stating that “If any law enacted by the House of Assembly of a state is inconsistent with any law validly made by the National Assembly, the law made by the National Assembly will prevail, and that other law shall, to the extent of its inconsistency, be void” (Section 4(5) CFRN 1999, As Amended).
In simpler terms, this means that only a law validly enacted by the federal legislature will take precedence over a state law, but this applies only when the state law conflicts with the federal law. However, if the state law mirrors that of the National Assembly on the same matter, the state law becomes inactive for the duration the federal statute is effective (A.G Lagos State v. Eko Hotels, (2017) LPELR – 43713 (SC)). Importantly, this principle applies only when the Federal law comprehensively covers the entire field concerning that subject matter. Therefore, where a federal law only covers a portion of the field, and the effect is to enhance a federal purpose on a concurrent subject, a state can still enact legislation to further its own purposes.
In the case of Adetona v. Attorney General of Ogun State (1984) 5 NCLR 299, 308-309, the court affirmed that if a federal law restricts its application to the federal level, allowing states to exercise legislative powers on the same subject in the concurrent list, states can effectively legislate on that subject already addressed by federal law. Understanding the principles of the doctrine of covering the field is crucial in advising clients on the potential issues of double taxation arising from conflicting laws passed by both the National Assembly and state Houses of Assembly (A.G. Lagos State v. Eko Hotels LTD & Anor (2017) LPELR- 43713 (SC)).
Moreover, when proposing legislation or recommending laws to legislatures, knowledge of this doctrine guides decisions on the appropriateness of the intended laws to avoid confusion and disputes. An awareness of the doctrine of covering the field is instrumental in identifying laws that, although in existence, are inadvertently null and void and should be challenged upon discovery.
For instance, in the case of Attorney General of the Federation v. Attorney General of Abia State (2002) 6 NWLR (Pt. 763) 264, the Supreme Court of Nigeria considered whether the National Assembly’s legislation on aviation precluded states from enacting laws on the same subject. The court held that where the National Assembly has legislated on a particular matter, state legislation on the same subject would be invalid, as the federal law covers the entire field.
Also, in the case of Attorney-General of Ogun State v. Attorney-General of the Federation (1982) 2 NCLR 166, the court held that wherein the exercise of the legislative powers of the National Assembly or a state House of Assembly, a law is enacted with the Constitution has already made provision for covering the subject matter of the federal Act or the state law, it is worthy of note that the constitution has covered the field on that particular subject matter. The National Assembly and the state House of Assembly cannot make a valid law to that effect anymore.

Challenges and Controversies
While the Doctrine of Covering the Field provides a clear framework for the distribution of legislative powers, it is not without its challenges and controversies. One primary concern is the potential encroachment on states’ autonomy and their ability to address local peculiarities. Critics argue that an overly broad application of the doctrine might undermine the principles of federalism and impede the ability of states to legislate on matters that directly affect their residents.
In some instances, states have challenged the application of the doctrine, asserting that the subject matter at hand is not exclusively within the purview of the National Assembly. This has led to legal battles and a nuanced examination of the constitutional provisions and legislative lists.
Harmonization and Cooperative Federalism
Efforts have been made to address the tensions arising from the Doctrine of Covering the Field through principles of harmonization and cooperative federalism. Harmonization involves a collaborative approach between the federal and state governments to ensure that laws complement rather than conflict with each other. Cooperative federalism, on the other hand, emphasizes intergovernmental cooperation to achieve common goals, recognizing that both levels of government have roles to play in addressing complex issues.
Recent Developments and Legislative Trends
In recent years, there have been notable developments and legislative trends that have further shaped the application of the Doctrine of Covering the Field in Nigeria. For instance, the advent of technological advancements and the digital economy has raised questions about the jurisdictional scope of federal and state laws in areas such as e-commerce, data protection, and cybercrime. Courts are increasingly faced with the challenge of determining whether existing federal laws adequately cover these emerging issues or if states can enact complementary legislation.
Additionally, environmental concerns, such as climate change and natural resource management, have brought about debates on the intersection of federal and state legislative powers. As environmental issues often have both local and national implications, finding a balance between federal oversight and state autonomy becomes crucial.
Constitutional Amendments and the Doctrine
The potential for amendments to the Nigerian Constitution has also fueled discussions on the Doctrine of Covering the Field. Proposals to reevaluate the legislative lists, particularly the exclusive legislative list of the National Assembly, have been put forward by legal scholars and policymakers. This reflects a broader discourse on constitutional reform and the need to adapt the legal framework to contemporary challenges and aspirations.
Judicial Activism and Case-by-Case Analysis
Judicial activism has played a role in shaping the application of the Doctrine of Covering the Field. Courts are increasingly engaging in a case-by-case analysis, carefully examining the specifics of each situation to determine whether the doctrine should be strictly applied or if there is room for concurrent legislation by states.
In cases where there is ambiguity or a lack of clarity in the legislative lists, courts have the responsibility of interpreting the Constitution to safeguard the principles of federalism while addressing the practical needs of governance. This approach acknowledges the dynamic nature of legal interpretation and the evolving needs of society.
Comparative Perspectives
To gain a comprehensive understanding of the Doctrine of Covering the Field in Nigeria, it is beneficial to explore comparative perspectives from other federal systems. Examining how other countries with similar federal structures manage the distribution of legislative powers can provide insights into best practices, potential pitfalls, and alternative approaches to the Nigerian context.

Recommendations for Future Consideration
As Nigeria continues to navigate the complexities of federalism and the Doctrine of Covering the Field, there are several recommendations for future consideration:
- Continuous Legal Education: Legal practitioners, lawmakers, and judges should engage in continuous legal education to stay abreast of evolving legal principles and the application of the Doctrine of Covering the Field.
- Public Participation: Encouraging public participation in the legislative process can help identify areas where federal and state laws can work together to address societal challenges. This approach ensures that legislation is responsive to the needs of the people.
- Flexible Legislative Lists: Periodic reviews and potential adjustments to the legislative lists can be considered to accommodate changing social, economic, and technological landscapes.
- Alternative Dispute Resolution: Emphasizing alternative dispute resolution mechanisms can help resolve conflicts arising from the application of the doctrine more expeditiously, avoiding prolonged legal battles.
In conclusion, the Doctrine of Covering the Field remains a cornerstone of Nigeria’s legal framework, influencing the relationship between federal and state legislatures. As the nation evolves, a dynamic and adaptable approach to its application is necessary, ensuring that it continues to serve the principles of federalism while addressing the complexities of contemporary governance.
