CUSTOMARY LAW IN NIGERIA: EVOLUTION, LEGITIMACY AND REFORM WITHIN A PLURAL LEGAL ORDER

Abstract

Customary law remains a foundational yet contested component of Nigeria’s plural legal system. While historically rooted in indigenous normative practices, its continued operation is shaped by statutory regulation, constitutional supremacy and judicial interpretation. This article critically examines the doctrinal foundations, evidentiary regulation, constitutional scrutiny and reform prospects of Nigerian customary law. Drawing upon the jurisprudence of the Supreme Court of Nigeria, comparative constitutional practice and the theoretical insights of the Historical School of Jurisprudence, the article argues that customary law is neither obsolete nor merely residual. Rather, it is a dynamic normative order that has survived colonial suppression, post-colonial marginalisation and constitutional transformation. Its future lies in principled harmonisation, selective codification and constitutionally grounded reform, not in displacement. Achieving that future requires the honest engagement of courts, legislators, traditional institutions and the communities that customary law serves.
