A trilogue meeting is a type of interinstitutional negotiation used in the European Union (EU) legislative process.[1] The bodies involved in trilogue negotiations are the European Commission, the Council of the European Union, and the European Parliament. The European Commission takes on the mediating function.[2]
It takes its name from a literary form, the trilogue, which means a conversation with three parties. Most references to "trilogues" in European legal studies refer to informal trilogue meetings. However, a conciliation committee, an official part of the ordinary legislative procedure (OLP) provided for in the EU treaties, is sometimes referred to as a "formal trilogue meeting".[3][1][4]
