The European Committee of the Regions as a watchdog of the principle of subsidiarity

In a resolution adopted on 1 February 2018, the European Committee of the Regions noted that a legislative proposal of the European Commission concerning a Regulation that changes the rules governing the EU regional funds for 2014-2020 did not comply with the principle of subsidiarity. Accordingly, the Committee considered challenging the legislative proposal before the Court of Justice if the proposal was formally agreed upon. Although at a later stage the European Commission decided to take into account the Committee’s argument and amended the proposal accordingly, such a context offers the chance to investigate more in detail the role of the Committee of the Regions in the legislative process of the EU and, more in particular, its role as a watchdog of the principle of subsidiarity. This paper aims to shed light on a rather neglected aspect of the EU constitutional practice, such as the potential of the Committee of the Regions to contribute to the legislative process, and answer the question of whether this Committee is the right body to guarantee compliance with the principle of subsidiarity.
