The European Commission has decided to refer the United Kingdom to the EU's Court of Justice for not fully implementing EU rules on the confidentiality of electronic communications such as e-mail or internet browsing. Specifically, the Commission considers that UK law does not comply with EU rules on consent to interception and on enforcement by supervisory authorities. The EU rules in question are laid down in the ePrivacy Directive 2002/58/EC and the Data Protection Directive 95/46/EC. The infringement procedure was opened in April 2009 (IP/09/570), following complaints from UK internet users notably with regard to targeted advertising based on analysis of users’ internet traffic. The Commission previously requested the UK authorities in October 2009 (IP/09/1626) to amend their rules to comply with EU law.
