This book investigates the underlying federal philosophy of the European Union's law-making function by tracing its evolution from a dualist structure to a cooperative model. Robert Schütze, a professor of European law, utilizes historical analysis and constitutional theory to argue that the European legal order has undergone a fundamental shift in its jurisdictional framework. By examining the division of powers between the Union and its member states, the author provides a systematic account of how these federal dynamics have matured over time.

Legal scholars and practitioners frequently cite this work as a foundational text for understanding the structural evolution of EU competence. Experts note the analytical rigor of the prose, which provides a clear conceptual map for navigating the complexities of European constitutional law.
