L’INFLUENZA DEI PRINCIPI DEL DIRITTO DELL’UNIONE EUROPEA SULL’ATTIVITÀ AMMINISTRATIVA NAZIONALE

The purpose of this thesis is to examine the general principles of European administrative law, recognized and interpreted by the European Court of Justice. An understanding of these fundamental elements of law is, therefore, vital to any study not only of the European Union law but also of the national legal system itself. Moreover the impact of these principles is pervasive: they are relevant in all branches and at all levels of the EU law. Because of the fundamental importance of the European principles for the development of administrative law, the first chapter of this study aims to identify the European principles that are more innovative for the national administrative activity. The second chapter analyzes the implications of article 1, paragraph 1, of the 7 August 1990, n. 241 Law, that was modified by the 11 February 2005, n.15 Law with the intent of enriching the catalogue of the general principles of administrative action. After the identification of the most important European principles for the action of the Public Administration and after the clarification of the scope and effect of the reference to «the principles of Community law», contained in the Article 1, paragraph 1, of Law n. 241/1990, the third chapter examines the national system of an administrative act contrary to European Union law. In this context, the final part of this thesis analyzes the influence of European legal order on the rules of liability for damages of the national Public Administration.
