This article briefly explores the reasons why the Committee of the Regions (CoR) has only partially accomplished its representative function. It is divided into three parts. In the first part I argue that the ambiguous nature of the CoR is the consequence of the polysemous notion of ‘region’ in EU law (Palermo, 2005) and of the very heterogeneous approach to the ‘federal issue’ in Europe. In the second part of the article I look at the recent developments that have given the CoR new powers, for instance in light of Art. 263 TFEU in order to defend its own prerogatives and Art. 8 of Protocol No 2 on the application of the principles of subsidiarity and proportionality. This will be done by looking at a recent resolution of the CoR on a proposal made by the EU Commission to amend Regulation (EU) No 1303/2013. Finally, I deal with some proposals that have been advanced to strengthen the role of the CoR, and their feasibility.
