In order to promote fair competition and free trade within the European Union, competition law, including merger control and cartel prohibition and the prohibition of abuse of a dominant position, limits the market behaviour of companies. If a company does not respect these limits, it can have all kinds of drastic consequences for the company, such as administrative fines, nullity of prohibited agreements or civil liability. After all, the European Commission, the ACM (Authority for Consumers & Markets) and other national competition authorities have far-reaching, parallel powers to monitor compliance with competition law restrictions and to investigate suspected infringements. Compliance with competition law therefore is, also considering the stricter enforcement, important for every company.
