The European Union is still primarily based on legal norms. The work provides a critical review of their commitment to shaping European cooperation over the last 50 years. To this end, contributions on fundamental questions of integration, their values, goals and methods, the institutional system and selected legal issues are reprinted, critically commented on and provided with references to current case law, legislation and literature. In the process, constants and variables of the integration process emerge. Weaknesses and advantages of individual methods also become clear. The book is of equal interest to actors in the Union, lawyers and political scientists. New product
