In recent judgments, the Court of Justice of the European Union (CJEU) has been developing its interpretation of the notion of “communication to the public”. This forms one of the exclusive rights of copyright holders that have been harmonised by the InfoSoc Directive (Directive 2001/29/EC (OJ 2001 L 167 p.1)). As was established in 2006 (Case C-306/05, Sociedad General de Autores y Editores de España (SGAE) v Rafael Hoteles, ECLI:EU:C:2006:764, at [31]), despite the lack of an explicit definition in that directive, the notion of a “communication to the public” must be given “an autonomous and uniform interpretation” throughout the EU. This finding initially resulted in the creation of a considerable amount of uncertainty for national courts. The gradual accumulation of information through subsequent CJEU judgments has begun to bring some clarity, while also raising new questions.
