The Ukraine is not a party to the Rome Statute of the International Criminal Court (ICC), but it has submitted declarations which may give the Court jurisdiction over certain crimes committed in Ukraine.
Consequently, Russian soldiers who take part in an invasion and commit war crimes, crimes against humanity, or other crimes within the Court’s jurisdiction, within Ukraine, could be subject to trial before the ICC, and in any event before the courts of any countries which prosecute such crimes on the basis of universal jurisdiction.
As a result, Russian soldiers who commit such crimes in Ukraine may never be able to travel to European or other countries which have ratified the Rome Statute, or which exercise universal jurisdiction, without running the risk of being arrested and tried for such enumerated crimes as they may have committed in Ukraine.
This would be be true for the rest of their lives.
