The Competition Authority is responsible for enforcing Irish and European competition law in Ireland and promoting competition in the economy. Competition law in Ireland is governed by the Competition Act 2002 and articles 101 and 102 TFEU. We do not ourselves make decisions on whether Irish or EU competition laws have been infringed. We investigate suspected breaches of competition law and either take legal proceedings ourselves in court or, in relation to hard-core cartels, send a file to the director of public prosecutions, who decides whether to prosecute on indictment. We can also block mergers between businesses that would substantially reduce competition and harm consumers. Any decision we take to block a merger or clear it with conditions can be appealed to the courts.
