The substantive law of the European Community is concerned with the development of the internal market and the free movement of goods, persons and services, and the right of establishment. These fundamental freedoms include the right of business undertakings to establish themselves in other Member States, and the rights of the workers to free mmovement and social security coverage. The rights to equal pay and sex equality are key features of the Community legal system. EC rules also cover competition law, mergers, public undertakings and state aids. The rules of EC business and social law are laid down in the EC treaty and in legislation made by the Community institutions, and are implemented and enforced by national authorities and courts. Knowledge of these matters is important for law students and legal practitioners alike. This book considers substantive community law in detail with extensive reference to the case law of the European Court of Justice. For a full understanding of EC law it is necessary to know about the institutions which make and enforce the substantive law, and about the possible implications of the Maastricht Treaty. This book informs on the law of the EC, its background, institutions and substantive law, with a sufficient level of detail for students and practitioners who need more than a beginner's guide.
