So far as matters upon which the European Union (EU) has legislated are concerned, the Commission claims competence to represent the views of the Member States in international fora. Thus, in the light of the acquis communautaire in the field of copyright and related rights established by the twelve Directives and two Regulations adopted to date on various aspects of these rights, the EU has for some years played an active role in multilateral external relations on the subject of copyright and related rights. The acquis communautaire in this context embraces the general principles of the EU Treaties and legislation, including the Directive and Regulations on copyright and related rights, as interpreted by the Court of Justice. In intergovernmental meetings, the spokesman for the Union is normally a representative of the Commission, speaking on behalf of the Union and its Member States. Sometimes, the spokesman is the head of the delegation of the Member State which at the time occupies the rotating Presidency of the Union. The EU first took a leading role in the negotiations which led to the adoption of the Agreement on Trade-Related Aspects of Intellectual Property Rights (the TRIPs Agreement) in 1994 but subsequently has claimed competence to represent the Member States of the Union in intergovernmental meetings on copyright and related rights convened by the World Intellectual Property Organization (WIPO). WIPO administers inter alia the Berne Convention for the Protection of Literary and Artistic Works (the Berne Convention), the Rome Convention for the Protection of Performers.
