EU Joins Special Tribunal to Hold Russia Accountable for Ukraine War

Summary

The European Commission proposes that the EU sign the Enlarged Partial Agreement (EPA) on the Management Committee of the Special Tribunal for the Crime of Aggression against Ukraine. The EU will become a founding member of the Management Committee, which will finance the tribunal, approve its budget, elect judges and prosecutors, and provide non‑judicial advice.

Background

• Russia began an unprovoked war against Ukraine in February 2022.
• The European Council condemned the aggression on 24 Feb 2022 and called for Russia’s full accountability.
• The UN General Assembly adopted resolutions on 2 Mar 2022 and 23 Feb 2023 demanding an end to the war and accountability for the most serious crimes.
• 39 EU member states referred the situation to the ICC on 2 Mar 2022, but the ICC cannot prosecute the crime of aggression under the Rome Statute.
• The EU, the High Representative, and the Council have repeatedly urged the creation of a special tribunal to try those responsible for the aggression.
• From January 2023 to March 2025, the Core Group (about 40 states, the EU, and the Council of Europe) drafted the legal instruments for the tribunal.
• The Lviv Statement (9 May 2025) reaffirmed the commitment to establish the tribunal.
• The Council of Europe’s Committee of Ministers approved the agreement between Ukraine and the Council of Europe (24 June 2025) and the EPA (25 June 2025).
• The EU signed a €10 million contribution agreement on 22 Jan 2026 to set up an Advance Team that will prepare the institutional, logistical and organisational foundations for the tribunal.

Legal basis

• Article 212 TFEU (technical and financial cooperation with third countries).
• Article 218(5) TFEU (Council decision to conclude an agreement).
• The EPA is a non‑binding instrument until the EU completes its internal procedures.

Subsidiarity & proportionality

• The EU’s participation complements, rather than replaces, national actions.
• The EU’s contribution is proportionate to the overall cost of the tribunal.

Budgetary implications

• The EU will pay an annual contribution once the EPA enters into force (likely after 2028).
• The €10 million Advance Team contribution covers staff costs for 2026–2027.
• The EU will also support evidence collection through the International Centre for the Prosecution of the Crime of Aggression (ICPA) and cooperation with Eurojust.

Other EU actions that align with the EPA

• Eurojust’s evidence database (CICED) and the ICPA (established July 2023).
• The Ukraine Facility Regulation (2024) and the Ukraine Compensation Mechanism (Register of Damage, Claims Commission).
• EU sanctions and the Freeze and Seize Task Force against Russia.
• EUAM Ukraine and the Atrocity Crimes Advisory Group.

Decision

The Council will adopt a decision authorising the Commission to notify the Secretary‑General of the Council of Europe of the EU’s intention to join the EPA and to participate in the adoption of the Council of Ministers’ resolution establishing the EPA. The decision takes effect on the day it is adopted.

Broader Context

This legislation is part of the EU’s broader effort to respond to Russia’s war against Ukraine. Since the International Criminal Court cannot prosecute the crime of aggression, EU countries are helping create a special tribunal specifically for this purpose. The EU’s involvement means it will be part of the management and financing of the tribunal, alongside other countries and international organisations. This aligns with ongoing EU actions like sanctions against Russia, support for Ukraine, and mechanisms to document and compensate war damages.

The initiative also reflects the EU’s commitment to international law, accountability, and coordinated action with partners like the Council of Europe and Eurojust. It strengthens the EU’s role in global justice efforts without replacing national courts.

Impact on EU Citizens

For most EU citizens, this decision won’t change daily life directly. However, it signals that the EU is actively supporting justice and accountability for international crimes. Taxpayer money will fund part of the tribunal, but only a small share of the overall cost.

Indirectly, it could affect EU citizens by:

• Reinforcing the EU’s credibility in international law and security matters.
• Supporting Ukraine and contributing to stability in Europe, which may have long-term security and economic benefits.
• Strengthening EU institutions that track crimes and coordinate with national authorities, which could improve legal cooperation across Europe.

Financial Transparency

The EU is contributing a small fraction of the tribunal’s total budget. Citizens can see exactly how funds are allocated: setup costs, annual contributions, and support for evidence collection. This shows an effort to be proportionate and accountable in spending public money.
