Theorising the Constitutional Status of Traditional Rulers and Customary Governance in Nigeria’s Federal System: Obi, Emir, and Obong Institutions

Traditional rulers and customary governance institutions occupy a constitutionally anomalous position in Nigeria's federal system: they are recognised in state laws and exercise significant de facto governance functions yet are not mentioned in the 1999 Constitution and lack formal constitutional status as governmental actors. The theoretical and public law dimensions of this constitutional invisibility, and its implications for understanding the actual governance architecture of Nigerian communities, represent a significant gap in comparative constitutional law scholarship. This study develops an original theory of the constitutional status of traditional governance institutions in Nigerian public law, examining the legal basis of Obas, Emirs, Obis, and Obongs' authority, the judicial characterisation of traditional ruler actions, and the appropriate constitutional accommodation of customary governance in a modern federal democratic state. The methodology combines a systematic doctrinal analysis of state traditional institutions laws from all six geopolitical zones, case law on traditional ruler governance actions from state High Courts from 2010 to 2023, comparative constitutional analysis of traditional authority accommodation in South Africa's Constitution and Uganda's traditional kingdoms framework, and qualitative interviews with 25 constitutional lawyers and legal anthropologists. Customary Law Constitutional Theory, Legal Pluralism Theory, and Post-Colonial Governance Theory provide the theoretical architecture. The study's original contribution is a Constitutional Accommodation Theory for Traditional Governance Institutions applicable to African federal states with persistent customary governance traditions. Findings generate a proposed constitutional amendment framework for traditional institution recognition and accountability.
