'Joseph Weiler's 'The Transformation of Europe' was a seminal article that placed previous developments in sharp perspective, and contained valuable insights on the future challenges facing the EU. The article has stood the test of time. This volume provides a fitting tribute to Weiler's article, with important contributions from prominent scholars in the field that reflect on Weiler's scholarship from a variety of perspectives.' Paul Craig, University of Oxford
