This unique work explores several core themes relating to the evolution and the achievements of the Constitution of Ireland. A distinctive feature is the comparative approach taken by several leading Italian scholars of public and constitutional law, and their approach to different themes of the Irish Constitution, examining the nature and implementation of the pertinent constitutional provisions and comparing them with the experiences of other European States. The book covers the most important areas of public law: civil liberties, form of government, public administration, and constitutional principles. It is the product of an international workshop held in Dublin in 2011, organized by the Italian Embassy with the support of UniCredit Bank. The book is a celebration of the 75th anniversary of the Irish Constitution.
