The project revolves around the Contact Group, which functions as a regional coordination mechanism for cross-border judicial cooperation in criminal matters. The Contact Group is composed of two representatives per each Western Balkan partner (prosecutors and/or police officials) appointed by their home authorities. The Contact Group meets regularly in various locations, either at Eurojust premises or in one of the Western Balkan partners.

There have been five meetings of the Contact Group since the project commenced. The first meeting took place in The Hague on 8 March 2023, followed by the second in The Hague on 15 May 2023, the third in Sarajevo on 5 July 2023, the fourth in Podgorica on 27 September 2023, and the fifth meeting was conducted online on 30 November 2023.

• On 26 June 2023, upon a proposal of DG NEAR, the Project Team organised a Webinar on admissibility of evidence obtained from SKY ECC and Encrochat networks, in cooperation with the European Judicial Cybercrime Network (EJCN), gathering more than 300 participants.
• The Regional Seminar on JITs in migrant smuggling cases took place in Sarajevo on 6 July 2023. This seminar was organised jointly with the JITs Network Secretariat and the Focus Group on Migrant Smuggling at Eurojust. It was the first event organised by the Project in the region and it was attended by more than 50 participants, including prosecutors and law enforcement officers from the six Western Balkans partners. The aim of the seminar was to introduce the JITs Network of National Experts and its Secretariat to practitioners from the Western Balkan region, as well as highlighting the benefits of joining the Focus Group on Migrant Smuggling. The seminar included a section on case studies, during which EU prosecutors presented and analysed successful JITs they signed with Western Balkan authorities.

The Seminar was aimed at promoting the Eurojust toolkit and the WBCJ Project’s financial support among Montenegrin prosecutors, with a specific focus on the benefits of JITs.
