Article 267 reference
Also known as reference for a preliminary ruling. Formerly known as a reference under Article 177 of the Treaty of Rome or Article 234 of the EC Treaty. A procedure under Article 267 of the Treaty on the Functioning of the European Union (TFEU) ( www.practicallaw.com/A35020) whereby national courts, in the course of proceedings before them, can put questions to the Court of Justice of the European Union ( www.practicallaw.com/A36017) (ECJ) either on the interpretation of relevant parts of the TFEU or relevant secondary legislation or on the constitutionality of relevant secondary legislation. The purpose is to try to ensure a uniform application of EU law throughout the European Union ( www.practicallaw.com/A36027). The ECJ is always careful to avoid expressing a view on how its ruling should be applied in the context of the national proceedings.
