With the entering into force of Regulation 1/2003 on 1 May 2004, the role of competition law and enforcement in both the EU’s and its Member States’ constitutional legal orders and economic policies have significantly changed. Ten years later, during the 4th ACELG Annual Conference we look back and reflect on 10 years of decentralized EU competition law enforcement.

Detail Summary
Date 14 November 2014
Time 09:30 - 17:00


On 1st May 2004, Regulation 1/2003 entered into force, introducing a fundamental change in the enforcement of Articles 101 and 102 TFEU. This date also marked a fundamental change in the history of the EU: ten new Member States joined the European Union. Regulation 1/2003 was evaluated 5 years after it took effect, but no such legislative evaluation has been envisaged ten years after. 

The role of competition law and enforcement in both the EU’s and its Member States’ constitutional legal orders and economic policies have significantly changed. In the enlarged EU, the Lisbon Treaty introduced a new Article 3(3) TEU; competition disappeared as an objective of the EU, but at the same time it did become a core constitutional value in many of the new Member States’ legal systems. Since then many new market sectors have been opened up to competition and the enforcement of competition laws has become crucial. Moreover, the economic crisis of the last couple of years has significantly challenged this newly anchored role of competition law enforcement in the EU and its Member States. 

The goal of this ACELG conference is to take stock of the various constitutional (legal and institutional) developments that followed the entering into force of Regulation 1/2003. The conference will discuss the constitutional implications of these developments in the EU’s and the Member States’ legal orders and evaluate its first ten years of functioning.
