On 13 May the Court of Justice of the European Union (“ECJ”) delivered a ground-breaking ruling on the application of the Data Protection Directive 95/46/EC (the “Directive”) to internet search engine operators. In its eagerly anticipated judgment, the ECJ ruled on key issues including the circumstances in which search engines must block certain information from being returned in the results of a search made against the name of an individual (even where those data were originally lawfully published by a third party), the so-called “right to be forgotten”, and the territorial application of the Directive.
