This engagement with OPG and other justice, law enforcement and security agencies of Ukraine has been and will continue to be driven by the needs of the Government of Ukraine and the parameters of its support will be developed in close consultation with OPG. To this end, it will closely link its activities to ongoing operational work in cooperation with EU Member States, third country partners and the International Criminal Court, including the Joint Investigation Team coordinated by Eurojust.

The ACA brings together a multinational group of war crimes experts from countries in the European Union, the United States, the United Kingdom and other countries. Due to the current security situation in Ukraine, the experts are mainly based in south-eastern Poland, but are operationally engaged in Ukraine, including through short-term assignments and on-site interactions with OPG staff and other committed international partners. If the security situation permits, it is expected that experts and support staff will be fully transferred to Ukraine.

The ACA activity will cover the coordination of two key elements:

  • OPG Advisory Group: Experienced war crimes prosecutors, investigators, military analysts, forensic specialists and other experts based in the region provide ongoing expertise, mentorship, advice and operational support to OPG and mobile justice teams on the ground, as well as a wider range of state and non-state actors.
  • Mobile court teams: Several Mobile Justice Teams (MJTs) are created and deployed to increase the capacity of OPG’s War Crimes Unit and regional prosecutors to conduct investigations in the field. The MJTs will be made up of international and Ukrainian experts and will be deployed at the request of OPG to assist Ukrainian investigators in the field. They will be part of the holistic chain of documentation, investigation and prosecution of serious international crimes led by the OPG.

The ACA is supported by the U.S. Department of State’s Bureau of Global Criminal Justice (GCJ) and the Bureau of International Narcotics and Law Enforcement Affairs (INL). ACA partners include the Sandra Day O’Connor College of Law at Arizona State University, Global Rights Compliance, and the International Development Law Organization (IDLO).
