This book is one of seven volumes that provides a comparative analysis of European public law. As the gradual transformation of Europe continues to leave its mark on domestic public law, the book provide an overview of the different sections of public law, including its istorical and constitutional foundations, its intellectual history, and open statehood, public law and public authority, and administrative and judicial review. Each volume includes scene-setting chapters laying open the heart of the issue, detailing the challenges for the field, and providing a roadmap for the individual country reports. Chapters address the individual legal orders of their country, permitting comparative analysis across jurisdictions. Finally, cross-cutting chapters examine the European approaches taken when dealing with specific legal challenges. This volume looks initially at the idea of a European public law as it exists today, and as it has been conceived in the past. Two chapters compare the administrative states of Europe and the USA, and a further nine chapters examine central questions of administrative law in their separate jurisdictions. Finally the complex relationship between administrative law and constitutional law is laid bare, before questions of statehood, typology, and transformation are addressed. A final chapter looks at the growing concept of ‘Europeanization’ in relation to public law.
