This paper attempts to address the question of how multilingualism in the EU might affect the consistency of private enforcement of competition law. In the literature, there have been concerns raised about the consistency of public enforcement of competition law, so in this paper attention has shifted to concerns about consistency of private enforcement. For the purposes of this paper, a distinction is drawn between rule-making and the application of competition law. The latter falls outside the scope of this paper. The article starts by going straight into aspects of public versus private enforcement of EU competition law and consistency of private enforcement of competition law. Next, by looking at examples of national rules implementing the EU Damages Directive, the author is going to discern what challenges for consistency of private enforcement of competition law are associated with the multilingualism in the EU.
