On 3 July 2023, the newly created International Centre for the Prosecution of the Crime of Aggression against Ukraine (ICPA) officially started operation at Eurojust. Designed as a judicial hub embedded in Eurojust, the centre will support national investigations into the crime of aggression related to the war in Ukraine. Through the centre, independent prosecutors from different countries will be able to work together in the same location on a daily basis, exchange evidence in a fast and efficient manner, and agree on a common investigative and prosecution strategy. The centre will benefit from Eurojust’s operational, technical, logistical, and financial structure. A key tool for the centre will be the Core International Crimes Evidence Database (CICED) managed by Eurojust. To start, five members (Lithuania, Latvia, Estonia, Poland, and Romania) of the Joint Investigation Team on alleged core international crimes committed in Ukraine (→eucrim news of 5 May 2023) and the ICC are participating in the ICPA alongside Ukraine. In a second step, the participation of other countries and organisations, such as the EU Advisory Mission to Ukraine, will be facilitated. Furthermore, countries in possession of information or evidence relevant to the investigation of the crime of aggression against Ukraine may also request to participate.
