On 12 December 2019, Eurojust officially became the European Agency for Criminal Justice Cooperation, with its new Regulation taking effect the same day (see also eucrim news of 18 February 2019).

Novelties set into motion under the Regulation EU) 2018/1727 include a new governance structure (with an Executive Board of six members), new powers for the national Members, new procedures for the work of the College, and stronger democratic oversight. Relations with other institutions and agencies such as the EJN, Europol, and the EPPO have been set out. The types of serious crime for which Eurojust is competent now include genocide and war crimes.

In addition, Eurojust is now run by a new data protection regime, adapting it to the revised EU legal framework on data protection. The European Data Protection Supervisor (EDPS) is responsible for the external supervision of Eurojust, replacing the Joint Supervisory Body (JSB). While the UK and Ireland decided to opt-in to the Eurojust Regulation, Denmark is not bound by it. Hence, on 11 December 2019, a cooperation agreement between Denmark and Eurojust took effect (see eucrim news of 20 December 2019).
