The fight against cartels is now one of the top priorities of all competition authorities who are very active and innovating to improve enforcement and deterrence. Within the EU, one of these innovations has been the EU cartel settlement procedure, first established in 2008.

The paper analyses key issues and draw lessons from the almost ten years of practice.
