According to the Penal Code of 1960, criminal laws purportedly based on sharīʿa ceased to exist in Northern Nigeria. In 2000, twelve states of Northern Nigeria sought to reintroduce Islamic criminal law, which had been partially in place prior to the 1960 law reforms. In pursuit of its vision to restore Islamic criminal law, the government of Bauchi state in Northern Nigeria set up a “Sharia Implementation Committee.” The Committee was charged with examining the legality and constitutionality of the proposed laws, inquiring into public opinion, and educating members of the public. To carry out this task, the Committee consulted Muslim jurists, state-trained lawyers, legal academics, and members of the public. This volume of Philip Ostien’s Sharīʿa Implementation Sourcebook contains the report of the Committee.
