4.5. Identifier assigned by the Court of Justice of the European Union
European case-law identifier (ECLI)
The European case-law identifier (ECLI) has been developed to facilitate the correct and unequivocal citation of decisions from European and national courts. It was introduced progressively by the Court of Justice of the European Union in 2014.
The Court of Justice of the European Union has assigned an ECLI to all decisions delivered by the European Union courts since 1954 (judgments, orders, opinions of the Court, decisions (review procedure)), to the opinions and views of the advocates general and to the information about these decisions (summaries and reviews, information on unpublished decisions).
The ECLI is composed of five mandatory elements, in Latin alphanumerical characters only, separated by a colon, as shown below.
Council conclusions inviting the introduction of the European case-law identifier (ECLI) and a minimum set of uniform metadata for case-law (OJ C 127, 29.4.2011, p. 1).
