 EU competition law has jurisdiction over cases which affect inter-state trade in the Union.Regulation 1/2003 of the European Commission "decentralised" the enforcement of competition law with a number of reforms designed to increase the enforcement of EC rules in national courts.The law is primarily enforced by the Competition and Consumer Protection Commission (which replaced the Irish Competition Authority on 31 October 2014), who review mergers, and investigate cartels and abuse of dominance by undertakings.
