Abstract: | Among the many important changes wrought by Regulation 1/2003are the decentralization of responsibility for enforcing EUcompetition law from Brussels to Member States and the creationof the European Competition Network to encourage coordinationand information-sharing among the 26 competition authoritiesin the EU. This article contrasts Europe's new system of competitionenforcement under Regulation 1/2003 with that of the UnitedStates. I focus upon two of the more significant features ofthe U.S. system: the dual legislative and enforcement authorityof the States and the Federal Government, and private enforcement.The Commission is presently evaluating measures to facilitateprivate enforcement and is set to release a Green Paper on thattopic later this year. I highlight a few characteristics thathave made private enforcement such a significant component ofthe U.S. antitrust regime, in some ways and at some times providingtoo much incentive for plaintiffs, at the expense of neutralor procompetitive business activity. |
