For 20 years, the U.S. Commission on International Religious Freedom (USCIRF) has monitored and evaluated religious freedom conditions in Nigeria. This year also marks 20 years since Nigeria’s return to democracy and the adoption of the 1999 Constitution, which outlines the federal system of government and the hybrid application of religious, customary, and civil laws. The Constitution provides that states shall have High Courts, and may also have Shari’ah and Customary courts of appeal where required. During the same time period, 12 northern Nigerian states have also re-integrated Islamic criminal law in various ways. While the Shari’ah laws are based on long-standing practices, receive widespread support from Muslims, and apply only to Muslims, state enforcement of religious laws presents serious challenges to fully respecting freedom of religion or belief.
