This is the first comprehensive collection of court decisions dealing exclusively with the relationship between European Community law and the national laws of the Member States. It contains 90 decisions given between 1962 and 1994 by both the Community's Court of Justice (20 cases) and the courts of the 12 Member States (70 cases). The volume includes the recent decisions of national courts concerning the Maastricht Treaty. Major recurring topics of the decisions are the supremacy and direct effect of Community law, its impact on national sovereignty and constitutional rights, and the remedies available before national courts for its enforcement. All the texts are presented in English, having been translated wherever necessary. Each decision is preceded by a concise summary and key-word heading. The volume also includes a systematic introduction, digest of key-word headings, table of cases and detailed index.
