European Competition Network (ECN)
"The European Commission and the national competition authorities in all EU Member States cooperate with each other through the European Competition Network (ECN).
This creates an effective mechanism to counter companies which engage in cross-border practices restricting competition. As European competition rules are applied by all members of the ECN, the ECN provides means to ensure their effective and consistent application. Through the ECN, the competition authorities inform each other of proposed decisions and take on board comments from the other competition authorities. In this way, the ECN allows the competition authorities to pool their experience and identify best practices."
