First principal article coming out of the Marie Curie Project has been published in the Journal of Common Market Studies. The article is entitled ‘Legitimacy and Multi-Level Governance in European Union Competition Law: A Deliberative Discursive Approach’ and is available electronically on the Journal of Common Market Studies’ website. This article investigates the moral (output) and procedural (input) legitimacy of the recent competition law reforms in the European Union. Following a discursive approach, the article looks into the roles played by institutions deliberating for citizens (consumer organisations, European Parliament and the Union Courts) in the reform process. This inquiry results in the questioning of the reforms’ legitimacy, and it also leads to broader conclusions regarding the legitimacy of multi-level governance: expert discourses overshadow potential deliberative qualities of networks, which exacerbates networks’ legitimacy problems. Also, the input/output legitimacy dichotomy appears problematic, as expert policy-making in the absence of citizen participation does not guarantee policies resonating with public interest.
