An Original Contribution to the Theory of Islamic Constitutional Democracy: Bridging Shura, Human Rights and Federalism in the Nigerian Context

The theoretical relationship between Islamic political principles, constitutional democracy, and federal governance remains contested in Islamic constitutional theory, with significant practical implications for multi-religious federal states like Nigeria where Islamic and democratic constitutional principles coexist. This study develops an original theoretical contribution to Islamic constitutional democracy, specifically addressing the conceptual bridging of Shura (consultation), universal human rights, and federalism in the Nigerian multi-religious federal context. A systematic theoretical methodology is applied, constructing the theory through engagement with Islamic political philosophy from Al-Mawardi, Ibn Khaldun, and contemporary Islamic constitutionalists (Rachid Ghannouchi, Tariq Ramadan, Abdullahi an-Na'im), democratic constitutional theory from Habermas, Rawls, and Mouffe, and federalism theory from Elazar and Watts. The theory is tested against Nigeria's constitutional architecture through analysis of forty constitutional court decisions involving Sharia-democracy intersections from 1999 to 2023. The original contribution is a Theory of Deliberative Islamic Constitutional Democracy specifying six institutional mechanisms for integrating Shura-based deliberation with constitutional rights protection and federal governance: Islamic deliberative institutions at state level, rights floor protections enforceable against Sharia legislation, structured inter-religious constitutional dialogue processes, Maqasid-based constitutional review, an Islamic constitutionalism review council, and a federal Islamic law coordination framework.
