On 8 November 2017, the French Banking Federation (FBF) appealed to the French Council of State against the notice by which the Autorité de contrôle prudentiel et de résolution (ACPR) stated its compliance with the guidelines on the oversight and governance arrangements of retail banking products issued by the European Banking Authority (EBA) on 22 March 2016. As the FBF challenged the compliance of those guidelines with Union law in support of the appeal, the Council of State referred a question to the Court of Justice of the European Union (CJEU) for a preliminary ruling. In particular, the Council of State asked the CJEU whether the content and purpose of these guidelines fell within the scope of the EBA’s powers.
