Regulatory framework The main Austrian antitrust law is the Cartel Act 2005, which came into force on 1 January 2006. The Cartel Act contains the rules on cartels, vertical agreements, abuse of dominance, mergers and enforcement procedure. The Competition Act contains provisions relating to the Federal Competition Authority (FCA) and its powers, and the Commission on Competition. Apart from the Cartel Act and the Competition Act, further rules on competition are set out in various other statutes such as the Neighbourhood Supply Act, which governs the relationship between suppliers and retailers. Other important rules covering areas such as de-monopolisation in formerly protected sectors have been brought about through several statutes, including the Telecom Act 2003 and the Postal Services Act 1997.
