The Judicial Network of the European Union (JNEU) is run by the Court of Justice of the European Union (CJEU).

It supports the exchange of case law between the Member States' courts and the CJEU. On a closed portal, the Member States' courts and the CJEU publish information on their case law concerning European Union law, on cases referred by national courts to the CJEU, and on scientific works and preparatory documents.
