Abstract
This essay examines the problems that many scholars raise when referring to the EU’s chances of implementing a true, original and effective social model, capable of renewing the Welfare State model developed after the Second World War. The analysis is conducted in the light of the process of ‘constitutionalisation’ in the European Union and of the Lisbon Treaty. Following a constructive approach, the author examines the current debate among European public actors on this issue, with particular emphasis on the ‘advanced enforcement’ of the Nice Bill of Rights evident in the jurisprudence of the European Courts as well as in recently published European Commission documents on ‘flexicurity’.
