This collection deals with challenges confronting public law and public administration in twenty-first century democracies across the world. It draws together contributions from leading scholars, examining cutting-edge topics, and projecting the scholarship forward. It emphasizes the importance both of justifying executive policymaking to citizens and of drawing on bureaucratic expertise and professional competence. Contributors examine the role of courts and argue for new forms of public participation that can incorporate democratic values into executive-branch policymaking. Finally, the work confronts problems in the administration of the criminal law that are generating increased public concern. Building on Rose-Ackerman’s scholarship, writers compare the American experience with contemporary developments in other leading democracies – in particular, Germany, France, the EU, Canada, and Latin America. The work will be an invaluable resource for academics, researchers and policymakers working in the areas of Administrative Law, Public Law, and Political Science.
