This book consists of interrelated essays by many past and present members of the EUI Law Department. The contributors are all well-known specialists in their fields, whose essays address such issues as the effects of integration upon certain national laws, the elaboration of EU law to provide a new framework for or replacement for national laws, the piece-meal development of specific legal strands of EU law and their intertwining with national or international laws, and the indirect and sometimes unintended consequences of European integration with regard to national, EU, or international law.
