European Union property law is an area of law that is still in its infancy. In past research I have focused on the influence of the internal market rules on national property law and on the extent to which the European legislature has enacted legislation dealing with matters of property law. EU property law is however not merely shaped by the European legislature but also by the Court of Justice of the European Union (CJEU). CJEU judgments on property law matters are predominantly found in the context of the VAT Directive. This Directive exempts certain transactions relating to immovable property from VAT, which calls for a definition of the term 'immovable'. This presentation for the Property Law Discussion Group will discuss the criteria developed by the CJEU to classify an object as either movable or immovable.
