Combining historical, conceptual, and empirical approaches, this article studies one of the most fundamental, yet underexplored, questions surrounding Regulation 1/2003: What limits European Union (EU) competition law places on the adoption and application of national competition and other laws? The relationship between EU competition and national laws was supposedly settled with the adoption of Regulation 1/2003. There are two exceptions to the rule in Article 3(1), under which national competition authorities and courts must apply EU competition law when applying their national competition laws, with primacy for EU provisions: Article 3(2) leaves room for ‘stricter’ national competition rules on unilateral conduct, and Article 3(3) for national rules pursuing a ‘predominantly different objective’. The solution offered by Article 3 is not workable. Through a historical study of the political discussions preceding Article 3’s adoption, a conceptual analysis of potential interpretations, and a systematic content analysis of French and German practice, this article reveals the lack of a dividing line between the notions of national competition laws and other laws. It calls for reform of Article 3 to ensure that conduct that should be governed by EU law is not assessed under national rules and standards that differ from one Member State to another.
