Reference for a preliminary ruling — Directive 2003/6/EC — Market manipulation — Penalties — National legislation providing for an administrative penalty and a criminal penalty for the same acts — Charter of Fundamental Rights of the European Union — Article 50 — Ne bis in idem principle — Criminal nature of the administrative penalty — Existence of the same offence — Article 52(1) — Limitations to the ne bis in idem principle — Conditions.
Outcome of the case
On those grounds, the Court (Grand Chamber) hereby rules:
1. Article 50 of the Charter of Fundamental Rights of the European Union must be interpreted as precluding national legislation which permits the possibility of bringing administrative proceedings against a person in respect of unlawful conduct consisting in market manipulation for which the same person has already been finally convicted, in so far as that conviction is, given the harm caused to the company by the offence committed, such as to punish that offence in an effective, proportionate and dissuasive manner.
2. The ne bis in idem principle guaranteed by Article 50 of the Charter of Fundamental Rights of the European Union confers on individuals a right which is directly applicable in the context of a dispute such as that at issue in the main proceedings.
