This book focuses on the substantive law of the EU with regard to the free movement of goods, persons, services, and capital. An introductory chapter outlines the background to EU law in this sphere: the role of free trade theory, the development of economic integration up to the present day, and the fundamental principles underpinning this development. The following sections then provide a detailed examination of the law relating to freedom of movement in each of the major categories - goods, persons and services, and capital - and a concluding section deals with the legal issues raised by the ongoing process of harmonization within the single market.
