The event entitled “Cartels” elaborates on key substantive and procedural developments in cartel enforcement. Cartels are regarded as the most detrimental violations of competition law and remain at the core of competition law enforcement both at the EU and national level. The seminar will therefore provide judges with a comprehensive overview of how to assess collusive behaviour, in particular the requirements of prohibition under Article 101 TFEU. The seminar will also focus on the sources of information and guidance to which judges could turn when faced with complex or novel issues.
