One of the most important EU consumer protection directives of the past decade, the 2005 Unfair Commercial Practices Directive, or UCPD, is brought under examination in this stimulating volume. Bringing together leading experts in the comparative law and consumer law domain, the book discusses the impact of the Directive and whether the many possible issues identified at its inception have been borne out in practice. Divided into four parts of 'Implementation, Approximation and Harmonization', 'Vulnerability', 'The UCP Directive and Other Regimes', and finally 'Enforcement', the volume examines the various policy developments, the growing body of case law, the decisions of relevant national enforcement authorities, as well as the legislative debates which have surrounded the implementation of the UCPD in Member States.This book provides a valuable assessment of the impact of a major EU directive almost ten years after its adoption, and as such will be of interest to academics, legal practitioners and the judiciary working in the areas of European and Consumer law.
