In many parts of Africa three different systems of laws are concurrently applied – the imported "Colonial" law, the indigenous customary law and Islamic law. In some countries the customary and the Islamic law are kept separate and distinct, while in others they are fused into a single system. This volume represents a unique survey of the extent to which Islamic law is in fact applied in those parts of East and West Africa which were at one time under British administration. It examines the relevant legislation and case law, much of which has never appeared in any Law Reports; the judges and courts which apply it and the problems to which its application give rise.
