On 25 April 2022 - for the first time in its history -, the Office of the Prosecutor of the International Criminal Court (ICC) signed an agreement to participate in a Joint Investigation Team (JIT). The respective JIT was set up on 25 March 2022 by Lithuania, Poland, and Ukraine with Eurojust’s support in order to facilitate investigations and prosecutions on core international crimes committed in Ukraine. At the end of May 2022, the judicial authorities of Estonia, Latvia and Slovakia joined the JIT.

The agreement with the ICC can be regarded as a clear signal that the international community undertakes all efforts to effectively gather evidence on core international crimes committed in Ukraine and bring those responsible to justice. Eurojust will accompany the JIT with operational, analytical, legal and financial support. Eurojust will also accommodate the coordination and cooperation between all national investigating and prosecuting authorities that have initiated investigations into core international crimes.

The EU is also financially supporting the ICC's investigations into international crimes committed by Russia in Ukraine. On 8 June 2022, the Commission announced that a new project was launched with a funding of €7.25 million. The project will support the Office of the Prosecutor of the ICC to build up capacities of large data storage on the respective international crimes in Ukraine.
