Constitutional Guarantees of Religious Freedom and the Regulation of Religious Bodies in Nigeria: A Study of Kaduna State

Religious freedom is guaranteed under Section 38 of the 1999 Constitution of Nigeria, and the state is constitutionally prohibited from adopting a state religion. However, the management of religious tensions and the legal regulation of religious bodies, particularly in religiously mixed states such as Kaduna in the North West zone, raise complex constitutional questions about the boundaries of permissible religious regulation. This study examines the constitutional framework for religious freedom and its practical operation in Kaduna State, with particular reference to the Kaduna State Religious Preaching Law 2016, the Religious Bodies Registration Decree, and their compatibility with constitutional religious freedom guarantees. A doctrinal methodology is applied, reviewing the 1999 Constitution, relevant Kaduna State laws, decisions of Nigerian courts on religious freedom, and the African Commission on Human and Peoples' Rights jurisprudence on religious rights. The study evaluates whether regulatory measures targeting religious preaching and religious body registration proportionally limit religious freedom or constitute unconstitutional restrictions. Available religious freedom literature from North West Nigeria identifies arbitrary preaching permits, discriminatory enforcement against minority religious groups, and state interference in mosque and church administration as the most documented constitutional concerns. The Proportionality Test and the UN Declaration on Religious Tolerance provide the comparative normative reference. Recommendations address standards for permissible religious regulation consistent with constitutional guarantees.
