Ukrainian prosecutors will work in the Office of the Prosecutor of the International Criminal Court (ICC) in Ukraine, where they will investigate Russia's crimes, according to the Office of the Prosecutor General of Ukraine.

Thus, Ukrainian prosecutors will collect evidence and support investigations into international crimes committed by Russia during its armed aggression against Ukraine.

In addition, they will work together with ICC prosecutors to ensure effective information exchange and coordination of actions.

According to the agreement signed by the Cabinet of Ministers and the ICC, Ukrainian prosecutors will be permanently present in the international justice office in Ukraine. This will significantly strengthen the evidence base in cases involving war crimes and crimes against humanity committed by Russia.

ICC

The International Criminal Court is an international organization established under the Rome Statute. It was adopted on July 17, 1998, in Rome, and entered into force on July 1, 2002, after 60 ratifications. Since then, the Court has only been able to consider crimes committed after that date.

The ICC's jurisdiction covers four categories of core crimes: genocide, crimes against humanity, war crimes, and the crime of aggression. The Court operates on the principle of complementarity — it only intervenes when the national system cannot or will not investigate and prosecute.

As of 2025, 125 states are parties to the Rome Statute. In addition, 29 states have signed but not yet ratified the relevant international agreement.
