摘要:The new Council Regulation (EC) No. 1/2003 on the implementation of the rules on competition laid down in Article 81 and 82 of the EC-Treaty, which came into force on 1 May 2004, brings fundamental changes in the application of European competition law. It replaces the Antitrust-Regulation No. 17 which has been in force for more than 40 years. Regulation No. 1/2003 establishes a system of direct applicability of Article 81(3) EC-Treaty, which abandons the requirement of notification as a key element of the old system under Regulation No. 17. Under the new scheme set up by Regulation No. 1/2003 Article 81(3) will be directly applicable. This enables national competition authorities and national courts to apply Article 81 and 82 of the EC-Treaty in their entirety, including paragraph 3 of Article 81. Although the new regulation is to be considered as an important step in strengthening and reinforcing European competition policy, in particular in view of the enlargement of the European Union, the numerous changes involve uncertainties which call for adjustment. The following article gives an overview of the new enforcement system for Articles 81 and 82 of the EC-Treaty, set up by Regulation No. 1/2003.
