In European Union (EU) law, the Meroni doctrine, which arose from cases C-9/56 and C-10/56 (Meroni v High Authority [1957/1958] ECR 133), relates to the extent to which EU institutions may delegate their tasks to regulatory agencies.[1] The doctrine is controversial,[1] notably because it would be anachronistic in view of the growing complexity of EU competences.[2]
In the view of some,[3] [4] the Meroni doctrine no longer holds since the 2014 European Court of Justice judgement in the UK v Parliament and Council case on the Short Selling Regulation, where the Court upheld most of the provisions that were delegated to the European Securities and Markets Authority by the co-legislators.
