The written contributions compiled in this book are based upon lectures held during a symposium on the administrative law implementation & enforcement of community law organized by the Directorate General Financial Control & the Dutch Law Association for the Study of Protection of Financial Interests of the EC. The topic is regarded from the perspective of both administrative practice & administrative law. While concentrating on the Dutch case the arguments put forward should also be of interest to the other EC countries since they also have to deal with both community law & national administrative law. Furthermore the book sheds light upon the development of community law in general. The importance of national administrative law for the putting into practice of community law is a topic which has received increasing attention from both the sides of administrative practice & legal science. At the same time it is clear that administrative law has acquired more & more community tasks & obligations. The latter development might point towards an European version of administrative law in the future.
