The migration of constitutional ideas across jurisdictions is rapidlyemerging as one of the central features of contemporary constitutionalpractice. The increasing use of comparative jurisprudence in interpretingconstitutions is one example of this. In this book, leading figures in thestudy of comparative constitutionalism and comparative constitutionalpolitics from North America, Europe, and Australia discuss the dynamicprocesses whereby constitutional systems influence each other. Theyexplore basic methodological questions which have thus far received littleattention, and examine the complex relationship between national andsupranational constitutionalism – an issue of considerable contemporaryinterest in Europe. The migration of constitutional ideas is discussed from avariety of methodological perspectives – comparative law, comparativepolitics, and cultural studies of law – and contributors draw on case studiesfrom a wide variety of jurisdictions: Australia, Hungary, India, SouthAfrica, the United Kingdom, the United States, and Canada.
