Thirty-six nations and the European Union formally committed to the Special Tribunal for the Crime of Aggression against Ukraine (STCA) last month in Chisinau, Moldova. This commitment came through the adoption of the Enlarged Partial Agreement (EPA), a key governing document for the tribunal. The EPA is one of three foundational agreements establishing the STCA, alongside a bilateral agreement between Ukraine and the Council of Europe, and the Tribunal’s Statute itself. The STCA aims to investigate and prosecute individuals responsible for the crime of aggression against Ukraine. This development marks a significant step towards operationalizing the court and pursuing accountability for alleged war crimes. The agreement signifies international collaboration in addressing the legal consequences of the conflict. Establishing the tribunal is expected to be a complex undertaking, but this agreement provides a crucial framework for its function.
