Through analyzing the implementation of a series of European Court of Justice rulings in the key member states of Germany, France and the UK, The End of Territoriality brings the high impact issue of policy changes to the foreground. The time sequencing of such changes is traced and scrutinized through a detailed investigation by Obermaier, followed by a comprehensive illustration on the full impact the policy amendments have had on the welfare states. By drawing extensively on original sources and new material, this volume will be of key interest to those studying and working within social policy, welfare, political sociology, and European law.
