A Hague-based international prosecutorial team launched preparation July 3 of case materials against Russia for the crime of aggression—an offense that is notoriously difficult to prosecute. The International Center for the Prosecution of the Crime of Aggression (ICPA) was established within Eurojust, the European Union's agency for judicial cooperation. The new office will draw together prosecutors from various European countries, as well as from the International Criminal Court (ICC), to gather evidence of Russian aggression in Ukraine. 

Read the announcement: "The war in Ukraine is the most documented in history, and, for the first time, active investigations into the crime of aggression are taking place while an armed conflict is still ongoing. At the same time, we are dealing with an international crime that has rarely been prosecuted and for which there is no standard practice."

The center will collect evidence with the awareness that it remains unclear where the case will ultimately be prosecuted—in national courts, a dedicated international tribunal, or before the ICC.

The initiative was initially announced by EU President Ursula von der Leyen in February, who said at the time: "Russia must be held accountable in courts for its odious crime."
