The decentralized enforcement regime of EU competition law is based on
the assumption that the obligation to apply the same Treaty provisions is
sufficient to ensure a uniform administration of the law. This paper
questions this assumption. Based on a systematic analysis of a large
database of cases, it presents empirical evidence indicating that the
Commission, EU courts and five national competition authorities have
followed very different interpretations of the law when applying Article
101(3)TFEU. The paper uses the debate over the types of benefit that can
be examined under Article 101(3) TFEU as an illustrative example of the
struggle between the different competition authorities in shaping the
future of EU competition policy
