Competition disputes within the EU may be heard by either the EU Commission – Competition Directorate-General (DG Competition) - and/or by a court.
It is important to know whether you are looking for a DG Competition decision or for a court judgment, and if the latter, to be aware that there is more than one court with jurisdiction.
Cases before DG Competition may result in a Commission decision, which will be published in the L series of the Official Journal. Commission decisions may be subsequently challenged in court.
The EU courts which hear competition cases are the General Court (EGC) (formerly the Court of First Instance) and the Court of Justice (CJEU).
