The first edition of the Practical Guide to the EU Labyrinth was published in 1991. 32 years and 16 editions later, Daniel Guéguen and Vicky Marissen now offer an updated and adapted edition. The Treaty of Lisbon of 1 December 2009 requires a comprehensive reform of this guide to understand the new procedures, new ways of conduct and new practices of the EU. After reading this guide, enriched with diagrams, examples and summaries, the structures, competences and procedures of the European institutions will no longer hold any secrets for you.
