Federalism remains a highly contentious issue in the United Kingdom, but however suspect the 'F' word may be, a substantial amount of devolution has already become part of the local landscape and more may yet follow. With the competence for a number of policies thus shifting from Westminster to Scotland, Wales, Northern Ireland, and in future perhaps even within England itself, foreign experience with federal and regional structures becomes a valuable source of ideas. In a series of contributions, distinguished experts from a wide range of legal systems including Canada, the United States, Germany, South Africa and the European Union present their experience, criticisms, and views concerning, inter alia, the distribution of power, judicial review and human rights protection in federalised and regionalised states. The book contains the papers from a conference jointly organised by the Institute of Global Law (UCL) and the Institute of Transnational Law (The University of Texas at Austin).
