Non-participating EU Member States
To this date, Denmark, Hungary, and Ireland do not participate in the enhanced cooperation on the EPPO. In May 2026, Hungary formally notified the Commission and the Council of its request to join the EPPO.
Ireland expressed its firm intention to participate in the EPPO in near future. Domestic preparatory work and ongoing operational cooperation with the EPPO are currently underway.
Denmark has an opt-out from the area of freedom, security, and justice (AFSJ).
Judicial cooperation in criminal matters with these countries is based on EU instruments for which the EPPO is notified as the competent authority pursuant to Article 105(3) of the EPPO Regulation.
To facilitate judicial cooperation and strategic exchange of information, a working arrangement with the Office of the Prosecutor General of Hungary entered into force on 6 April 2021 and a working arrangement with the Danish Ministry of Justice entered into force on 31 August 2023.
