The special tribunal against Russia’s aggression enters the practical stage: what Kyiv announced on April 16, 2026

On April 16, 2026, the official internet representation of the President of Ukraine published material on the key stages of launching a special tribunal for the crime of aggression by Russia against Ukraine. It is from there that the main data on the current state of the project, its legal basis, international support, and the next steps towards a full launch are taken.

This concerns an international mechanism that should hold the top political and military leadership of Russia accountable for the very decision to start and conduct an aggressive war against Ukraine. For Kyiv, this is not only a matter of symbolism but also of law: the Ukrainian side emphasizes that existing international mechanisms do not fully address this issue, and therefore a separate tribunal specifically focused on the crime of aggression is needed.

For the Israeli audience, this topic is particularly sensitive.

In a world where war crimes, terror, state violence, and the limits of international law are increasingly discussed, the question of personal responsibility for the war itself takes on much greater significance than just another diplomatic process. Ukraine is now trying to ensure that Russia’s aggression is framed not only as a political reality but also as a separate category of international punishment.

Why Kyiv needs a separate tribunal

The Ukrainian position boils down to one key thesis: The International Criminal Court cannot fully consider the crime of aggression against Ukraine, leaving a legal gap. It is precisely to close this gap that a special tribunal is proposed. The Ukrainian explanation emphasizes that this will be the first tribunal for the crime of aggression since World War II and the third such precedent in history after Nuremberg and Tokyo.

This is not just a legal detail.

In essence, Kyiv is seeking to ensure that international law once again learns to punish not only for the consequences of war but also for the very decision to start it. This approach is important not only for Ukraine. It affects the entire international order because it answers an old but increasingly pressing question: what to do if a major state starts a full-scale war and existing institutions cannot quickly and directly respond specifically to the top leadership.

For Israel, there is a separate interest here. The Israeli political and legal discourse has long existed in a world where international law constantly faces challenges of war, self-defense, and responsibility. Therefore, the Ukrainian attempt to create a separate mechanism for Moscow’s aggression is not a peripheral European plot but part of a broader struggle over how the international system will work in an era of protracted wars.

What has already been done

According to the Office of the President of Ukraine, the main legal stage of work on the tribunal has already been completed.

For more than two years, an international coalition of states has been preparing the legal basis for the creation and launch of this institution. Now, as Kyiv emphasizes, the process is moving from a political decision to a practical launch.

Ukraine has already ratified a bilateral agreement with the Council of Europe. In addition, since February 2026, an advanced group has been working in The Hague and Strasbourg, engaged in the organizational preparation for the launch. This group is supposed to address issues preceding the creation of a steering committee, which will then select judges and prosecutors. The European Union has allocated 10 million euros for its activities.

The next step, according to the Ukrainian version, should take place on May 14-15 in Chisinau, where the Council of Europe expects to advance towards formalizing the agreement on the steering committee. Kyiv also states that support already confidently exceeds the minimum threshold required for signing: the first 20 countries have confirmed their intention to join the process. Among them are Ukraine, the United Kingdom, Germany, France, the Netherlands, Poland, Sweden, Lithuania, Latvia, Estonia, Norway, Spain, Portugal, Slovenia, Croatia, Luxembourg, Iceland, Moldova, Costa Rica, and Austria.

How the launch will be structured and what should work next

The Ukrainian side describes the launch of the special tribunal in two phases. The first is transitional. At this stage, in The Hague, the framework of the future institution is essentially being assembled: a registry of 15 judges is formed, a registrar is appointed, key personnel are recruited, procedural rules are approved, international cooperation agreements are established, and administrative and technical infrastructure is created. Justice as such is not yet being administered at this moment.

This is an important nuance that is often lost in headlines.

The tribunal is not activated with a single button. First, the machine itself is created: rules, people, premises, security, international connections, document flow, technical base. Only after this does the second phase begin — full-fledged work, including investigations, bringing charges, judicial procedures, and delivering verdicts on the crime of aggression.

Ukraine explicitly states that it expects a full launch as early as next year. This is an ambitious goal, and it shows that Kyiv does not want to stretch the process into an indefinite future but rather quickly turn the political coalition into a functioning international mechanism.

NANews — News of Israel | Nikk.Agency in this context can view this process not as a purely Ukrainian legal campaign but as an attempt to redefine the boundaries of what is permissible in international politics. If such a tribunal indeed starts functioning, it will be a signal not only to Moscow but to all regimes that might expect that the very decision to start a war will remain without a separate legal response.

Why this is more than just a European initiative

At first glance, it may seem that this is purely a European process surrounding Russia’s war against Ukraine. But in reality, the stakes are higher. If the international community can bring this mechanism to a working form, a precedent will emerge that will influence future conflicts far beyond Eastern Europe.

This is why the topic is important for Israel.

Israel lives in a reality where international legal mechanisms constantly intersect with issues of war, defense, limits of authority, and personal responsibility. Any new institution of this level automatically becomes part of the global legal landscape, which sooner or later affects the Middle East as well. For this reason, the launch of the special tribunal for Russia’s aggression is not a distant foreign process but an event worth closely following in Israel.

What this date and this source mean

The fact that the message was published on April 16, 2026, on the website of the President of Ukraine is significant in itself. It is not a leak, not a comment from an individual deputy, and not an external interpretation, but an official fixation of the Ukrainian authorities’ position at the moment of the project’s transition to the next stage. Formally, this means that Kyiv considers the legal basis assembled and ready to move the tribunal topic from the mode of diplomatic negotiations to the mode of practical assembly of the institution.

This is the main meaning of the news.

Ukraine no longer speaks of the special tribunal as a distant idea or moral demand. It speaks of it as a mechanism that already has a legal structure, an international coalition, funding for the preparatory stage, and a calendar of next steps. This means the issue is gradually moving from the realm of political statements to the space of concrete architecture of international justice.
