Joint investigation team into alleged crimes committed in Ukraine

Just three weeks after the war began, Eurojust supported the establishment of a JIT into alleged core international crimes committed in Ukraine. The speed at which the JIT was set up between Ukraine, Lithuania and Poland, followed by the prompt membership of four additional countries (Estonia, Latvia, Slovakia and Romania), the participation of the ICC and later also Europol, and a Memorandum of Understanding with the United States, has sent a clear message that no effort will be spared in gathering evidence and bringing those responsible to justice. The JIT is enabling close cooperation between all parties involved, and an effective and swift exchange of information and evidence.

Representatives of the Ukraine JITThe aim of the JIT is to facilitate investigations and prosecutions in the States concerned, as well as those which could be taken forward to the ICC. The Agency provides critical support to all JIT parties, including to investigators on the ground in Ukraine.

Eurojust ensures that the work of the JIT remains aligned with the various national Ukraine-related investigations currently ongoing in over 20 countries. During 2022, 18 cases were opened at Eurojust by national authorities in 8 Member States and 2 third countries in support of ongoing investigations in relation to war crimes and crimes against humanity, following Russia’s invasion of Ukraine. Ukraine, via the Ukrainian Liaison Prosecutor at Eurojust, is involved in all of these cases.

Support to the JIT on alleged core international crimes committed in Ukraine

The Network of National Experts on Joint Investigation Teams (the JITs Network) is a network of national judicial and law enforcement practitioners who promote the use of JITs by competent national authorities. The JITs Network is supported by the JITs Network Secretariat, which is hosted by Eurojust. The JIT investigating alleged core international crimes committed in Ukraine relies on Eurojust’s and the JITs Network Secretariat’s legal, analytical, financial, logistical, administrative and operational support.

The JITs Network Secretariat has played an active role in supporting the JIT, including in the preparation of the JIT agreement and appendix on cooperation with the ICC, and by assisting the JIT parties with a range of legal issues. The JITs Network Secretariat also provides the JIT with financial support and equipment for JIT parties to communicate securely. To respond to the JIT’s specific needs, the JITs Network Secretariat has ensured agile support through its standard, urgent and exceptional funding procedures.

Joint investigation team for crimes committed in Ukraine

Just three weeks after the war began, Eurojust supported the establishment of a joint investigation team (JIT) into alleged core international crimes committed in Ukraine. The JIT, originally set up between Ukraine, Lithuania and Poland, soon extended its membership to four additional countries (Estonia, Latvia, Slovakia and Romania), and added the participation of the ICC, Europol, and a Memorandum of Understanding with the United States. The JIT allows for close cooperation between all parties involved, and an effective and swift exchange of information and evidence.

A joint investigation team (JIT) is the most advanced tool in international cooperation in criminal matters. It is a team in which judges, prosecutors and law enforcement officials work together on a transnational criminal investigation, based on a legal agreement between two or more countries for a fixed period. Eurojust has been assisting countries to set up and operate JITs since 2009.
Eurojust supported Lithuania, Poland and Ukraine in setting up the JIT on 25 March 2022, the International Criminal Court and later Europol in becoming a participant, and the extension of the JIT to four more EU member states. The Agency will support the JIT partners in the entire process with operational, analytical, legal and financial assistance. Eurojust also accommodates the coordination and cooperation between all national investigating and prosecuting authorities who have initiated investigations into core international crimes.
The JIT was set up by Lithuania, Poland and Ukraine. On 31 May 2022, Estonia, Latvia and Slovakia became members, followed by Romania on 13 October 2022. Eurojust, Europol and the ICC are participants in the JIT. The JIT’s seven national authorities signed a Memorandum of Understanding with the United States Department of Justice on 3 March 2023.
While it cannot be excluded that other EU Member States will join the JIT at a later stage, it is important to keep the size of the JIT limited so the number of members does not negatively influence the decision-making processes. The Member States that joined so far are all in possession of large amounts of evidence in the form of witness and victim testimonies coming from Ukrainian refugees.
