If you are directly affected by the practice which you suspect restricts competition and are able to provide specific information, you may want to lodge a formal complaint, which must fulfil certain requirements. The complaint form (“Form C”) is available on the Commission Regulation (EC) No 773/2004 of 7 April 2004 relating to the conduct of proceedings by the Commission pursuant to Articles 81 and 82 of the EC Treaty [1]. Official Journal L 123, 27.04.2004, p.18-24 (see the form on the last page “Annex”). Information on how the Commission handles complaints is available on the Commission Notice on the handling of complaints by the Commission under Articles 81 and 82 of the EC Treaty (Articles 101 and 102 TFEU) (Official Journal C 115, 9.5.2008, p. 88–89). You can provide information on a specific market where you may have concerns regarding compliance with EU competition rules by e-mail to comp-market-information@ec.europa.eu
