THE HAGUE, Netherlands (CN) — While Ukraine’s military advisers are busy fighting off Russian aggression, the country’s legal experts have been searching for every possible avenue to bring Moscow to justice.
Ukraine hasn’t let the ongoing war stop it from attempting to hold perpetrators accountable. According to Myroslava Krasnoborova, Ukraine’s liaison prosecutor at Eurojust, European Union’s judicial cooperation organization, the country is investigating more than 71,000 allegations of war crimes, crimes against humanity and other serious offenses relating to the war.
Ukrainian prosecutors have, to date, secured 26 convictions in their national courts. A 21-year-old Russian soldier sentenced to life in prison for the killing of an unarmed Ukrainian civilian was the first person found guilty of war crimes committed during the invasion, a mere 11 weeks into the full-scale conflict.
Kyiv has had broad international support in its pursuit of justice. Less than a month after the Russian invasion began, Ukraine, Lithuania and Poland set up a joint investigative team to look into genocide, crimes against humanity and war crimes. They have since been joined by Estonia, Latvia, Slovakia, Romania, Eurojust and the International Criminal Court, or ICC.
“Our task is to facilitate,” Krasnoborova said.
According to Eurojust, 21 other countries have opened investigations into possible crimes committed in Ukraine under the legal principle of universal jurisdiction. On Thursday, the organization announced the creation of a new database to allow countries to store evidence related to those investigations.
The Hague
The ICC – the world’s only permanent court for the prosecution of genocide and crimes against humanity – completed an initial investigation into Russia’s activities in eastern Ukraine and its annexation of the Crimean peninsula in 2020, concluding there was “a reasonable basis at this time to believe that a broad range of conduct constituting war crimes and crimes against humanity.”
Neither Russia nor Ukraine are parties to the Rome Statue, which created The Hague-based court in 2002, but Ukraine gave the ICC partial jurisdiction to investigate war crimes in 2014.

In May 2022, the court deployed a team of 42 investigators, forensic experts and support staff - the largest ever - to collect evidence of war crimes.
“Now more than ever we need to show the law in action,” the ICC's chief prosecutor, Karim Khan, said in a statement at the time.
A jurisdiction gap
Although cases at the ICC can take years to complete, the court at least has jurisdiction for war crimes, crimes against humanity and genocide in the Russia-Ukraine conflict. It cannot, however, look into the crime of aggression.
Aggression - the act of invading another country - is one of the core crimes established by the Rome Statute but ICC member states couldn’t agree on a definition when the treaty was signed. So they kicked the can down the road, only later creating a definition at the Kampala Review Conference in 2010.
The so-called Kampala Agreement includes a carve-out for non-member states, mostly as a concession to the United States, France and the United Kingdom, countries with a history of engaging in military actions beyond their own borders. The Russian Federation isn’t a party to the Rome Statute, so no act of military aggression it perpetuates could be prosecuted at the court.
“There’s a gap,” Astrid Reisinger Coracini, a senior lecturer in international law at the University of Vienna, said in an interview. She and a number of other legal scholars have been pushing for the creation of an ad hoc tribunal to cover the crime of aggression.
A new court?
The full-scale invasion brought to the forefront a problem international legal scholars have complained about for years: no court has jurisdiction to try aggression committed by non-ICC countries.
