The body of national law derived from EU directives and regulations expands into all areas of government, and officials in both national and EU administrations play an increasingly active role as administrators and enforcers of EU law. Therefore, they need sufficient understanding of legal norms to avoid actions incompatible with EU legislation, leading to compensation claims against them and their authority. On the other hand, regulatory affairs professionals from business and professional associations are required to possess good knowledge of the EU legislative framework in order to actively influence the EU law-making process. This tutorial provides a concentrated, in-depth introduction into the most important rules of EU law. It is divided into two modules, starting with the EU legal framework and decision-making process, moving on to the new comitology system after Lisbon, and ending with Internal Market rules and proceedings before the Court of Justice. Case studies and workshops will allow participants to enhance their skills in solving legal problems and applying their knowledge in a practical legal context.
