In February 2006 the Court of Justice of the European Union (CJEU) delivered its ruling in Halifax, a case concerning the interpretation of EU secondary legislation on VAT. The judgment represented the culmination of a long process, with the Court referring for the first time to the ‘principle of prohibiting abusive practices’. Yet, Halifax also represented the beginning of a new process: the discussion over the significance of the newly designated ‘principle of prohibition of abuse of law’. Fundamental questions immediately arose and were the subject of intensive debate such as: the scope of application of the principle; how would the abuse test be applied; and, the nature and implications of this ‘principle’ - interpretative, general, or neither. This research reviews and considers the ongoing debate over the development of an EU principle of prohibition of abuse of law. It reflects on the role of the principle within the field of free movement of persons, in the context of the literature on convergences and divergences between the fundamental freedoms. It then proposes the notion of reverberation as a new conceptual framework for the analysis of the development of general principles of EU law.
