KYIV, Ukraine – The Constitutional Court, Ukraine’s highest legal power, was in crisis before Russia’s invasion in 2022. Now the country, in the middle of armed conflict, must remake its legal institutions if it wants to prosecute Russian aggressors captured in its territory.

From judges with conflicts of interest to alleged presidential interference, to backtracking corruption efforts, Ukraine must find a way to rectify its courts quickly. After a series of failed judicial reform bills, President Zelensky reconvened the Commission on Legal Reform. During the initial days of the Russian invasion, the Constitutional Court delayed major rulings, but now the Court seeks to prosecute individual Russians and perhaps even Russia as a whole for the crime of aggression. 

While negotiations on an ad hoc tribunal for the crime of aggression have garnered the majority of the media attention, Ukrainian prosecutors have forged ahead and begun domestic investigations while the international community determines the crime of aggression question. The Ukrainian criminal code prohibits the crime of aggression under Article 437. This includes “‘the planning, preparation, initiation and conduct’ of aggressive war, as well as ‘participation in conspiracy aimed at commission’ of such actions.” The Ukrainian code does not require the prosecuted individual to be in a position of leadership, unlike the Rome statute so even ordinary fighters and soldiers can be found guilty of aggressively waging war and the associated actus reus. 

The first conviction of the crime of aggression in the Ukrainian courts happened in May 2022, when 21-year-old Russian tank commander, Vadim Shishimarin was jailed for life after shooting an unarmed civilian, 62-year-old Oleksandr Shelipov, a few days after the invasion began. By July 2022, Ukraine’s prosecutor-general, Iryna Venediktova, and her office were investigating more than 21,000 war crimes and crimes of aggression allegedly committed by Russian forces. By March 2023, at least 26 war crimes suspects had been convicted by Ukrainian courts.

Before Russia’s invasion, national courts rarely saw aggression cases. Now, prosecutors are beginning to align Article 437 of the Ukrainian criminal codes to a more narrow scope, similar to the Rome statute. In the past, legislative attempts to bring Article 437 up the Rome standard failed. These prosecutions offer an interesting case study, as they show legal advocates conforming the code to international standards when the legislation and courts themselves have deprioritized doing so. Even with the Office of the Prosecutor General of Ukraine (OPG) sending guidance on standardized prisoner of war (POW) immunity, prosecutors seemed to be conforming to international humanitarian norms on combatant immunity fairly seamlessly.

Despite its corruption crisis, in February of this year, the Court issued a decision on an Article 437 case. It clarified who could be found guilty of the crime of aggression, further aligning Ukraine with international standards, rather than the criminal code’s broad definition. When the decision was released, 99 criminal aggression cases were registered, including cases against typical defendants, like military commanders, foreign intelligence service workers, and high-level state officials, but also including 30 “instigators of war” such as Russian singers and university rectors. While many–if not most–of these will take place in absentia, whether the Court can successfully rule on an atypical defendant’s crime of aggression poses an interesting challenge for the Court.

Additionally, Ukraine’s domestic prosecutors have an important opportunity to set a precedent for how the crime of aggression could be handled at national levels. This could set customary international law norms in an area that has seen little activity in the past century, which could be key to protecting the right to life. It is interesting to note that the list of potential defendants does not include notable suspects in aggression cases like President Putin himself and other members of the Troika. The Court seems committed, at least right now, to preserving the immunity of the Troika before its courts. It seems generally accepted that these personal immunities cannot be surpassed at a national level and will need some kind of extraordinary judicial response.

ICC Seeks to Prosecute a Military Mastermind

THE HAGUE, Netherlands – Since March of 2023, the ICC has sought to arrest Russian President Vladimir Putin and the Commissioner for Children’s Rights, Ms. Maria Lvova-Belova. However, as Russia is not an ICC signatory, it is unlikely that Putin or Lvova-Belova will be extradited for trial soon.

Both are allegedly responsible for war crimes related to unlawful deportation and transportation of population, specifically children, from Russian-occupied areas of Ukraine as far back as 2022 in violation of Rome Statute Articles 8(2)(a)(vii) and 8(2)(b)(viii). Incidents identified by the prosecutor’s office include deporting children removed from orphanages and child care homes. Many of these children were allegedly given up for adoption in the Russian Federation, and Russian law was changed via presidential decree to expedite citizenship. These acts demonstrate an intention to remove these children from their home country permanently, which violates the Fourth Geneva Convention. Moscow has denied the allegations and called the warrants outrageous.

Pre-Trial Chamber II considered, based on the Prosecution’s applications in February 2023, that there were reasonable grounds to that each suspect may bear responsibility for the unlawful deportation of population and the unlawful transfer of population from occupied areas of Ukraine to the Russian Federation, particularly in prejudice of Ukrainian children. The Court had evidence of individual criminal responsibility for both under Article 25(3)(a) of the Rome Statute and against Putin for failure to properly control civilian and military subordinates under Article 28(b). The warrants were considered in secret to protect the witnesses and investigation.

Prosecuting a military mastermind is no easy task and could undermine the Court; however, as the crimes addressed are allegedly ongoing, there is some hope that despite the unlikelihood of extradition, public awareness of the warrants may prevent further crimes. The Chamber considered this to be in the interest of justice and allowed the Registry to publicize the warrants’ existence, the suspect’s names, the warrants’ crimes, and the modes of liability the Chamber established.

The UN Commission of Inquiry of Ukraine found that Russian authorities took over 16,200 children out of Ukraine into Russia. The same Commission found evidence of rapes, torture, and killings, and has been investigating as far back as 2013 before the illegal annexation of Crimea. While the ICC can bring a prosecution against political leaders for waging an aggressive war, the Court seems to be focusing on civilian and children’s rights for now. Additionally, while the warrants recognize these acts as war crimes, commentators are making the case that the conduct also constitutes genocide and crimes against humanity. The decision to pursue these as war crimes may be an indication of evidence related to intent. With both the alleged crimes and evidence collection ongoing, the charges may be amended.

The Court has no power of enforcement instead relying on the 124 nations that are signatories to the Rome Statute to arrest those indicted of war crimes or crimes against humanity if they visit their territories. And yet, the Court issued the warrants. The decision to pursue charges against Putin sends a strong signal to low-level perpetrators that none are immune from prosecution and may serve as a deterrent. Plus, while Putin is not the first sitting head of state to be indicted, he is the first leader of a P5 country to be indicted. The ICC arrest warrants have impacted Putin internationally. He did not attend the BRICS summit in August 2023 in South Africa. Besides hindering potential international travel for Putin, the warrants make meeting with Putin less appealing. The stakes for engaging with Putin are becoming increasingly high for foreign governments. Combined with sanctions, the ICC warrants make it harder to ignore Russian actions in Ukraine and the brutality of its war. Even as many celebrate the ICC’s announcement, the Ukrainian government and like-minded partners continue to press for international support for the establishment of the tribunal to hold Russia accountable for the full breadth of crimes committed, specifically the crime of aggression.

International Community Calls for a New Court to Prosecute the Crime of Aggression

Shortly after Russia launched its unlawful, full-scale invasion of Ukraine in February 2022, many began advocating for a new tribunal to prosecute Russian leadership for the crime of aggression. With 30 core states discussing the creation of a new adjudicative body, proponents are pushing for a way to address Russia’s breach of the international order and create deterrence in the future.

First recognized by the International Tribunal at Nuremberg, the crime of aggression, as defined by Article 2(4) of the UN Charter, prohibits the use of force, barring narrow exceptions. It imposes criminal liability on those in violation. Largely dormant throughout the Cold War, the International Criminal Court’s (ICC) Rome Statute sought to bring the crime under its jurisdiction but controversy at the time has left both the definition and activation apparently in limbo. Even with the additional Kampala amendments created in 2018 after the atrocities in Uganda, the grey zone remains. This has led many to call for a separate tribunal, akin to the one established at Nuremberg, to handle aggression cases stemming from the Russo-Ukrainian War. Beyond WWII, cases prosecuting aggression are scant. The UN Security Council set up courts to try the perpetrators of atrocities in Yugoslavia and Rwanda in the 90’s but with Russia as a permanent member, this is not a viable option. 

Further bolstering their demands, the Rome Statute has a major loophole: only parties to the Rome Statute fall under ICC jurisdiction. This means Russia, a non-party, cannot be tried by the Court currently. Additionally, domestic courts afford many members of The Russian Troika, including Putin, immunity. Coupled with the lack of precedent for prosecuting this crime generally, the ad hoc tribunal is becoming more compelling. 

Three major legal solutions have emerged. The first is a multilateral treaty between Ukraine and willing states, similar to the International Military Tribunal at Nuremberg. The second is a Ukraine-UN tribunal created via resolution. The last is a domestic-international hybrid chamber based in Ukraine. The first two circumvent the troika prosecution problem, and the deputy head of Ukraine’s Presidential Office has rejected the third option as unconstitutional. Many are opposed to a tribunal that would present the crime of aggression as something bilateral, between Ukraine and Russia alone, but much of this hinges on the level of international participation.

Because the crime of aggression carries a unique gravity, many are advocating for a clearly defined and replicable solution to serve a deterrent effect. In the meantime, many efforts to gather and preserve evidence of aggression are ongoing. EU member states have already agreed to support establishing a Centre for Prosecution in the Hague with American endorsement. This staggered approach has come with benefits already. As “the mother of all crimes”, whatever option the world chooses will likely become precedent in the future, further complicating the matter. As worries of selective justice and tribunal legitimacy continue, how to prosecute the crime of aggression is a legal question we may finally get an answer to; however, it will also be impossible to separate these two nations’ complex, centuries-long history without prosecution, definition, and resolution. As accountability efforts continue, Ukraine must determine which normative expectations it seeks to abide by and consider negotiating the Rome Statute and Kampala Amendments or developing a tribunal system prepared to adjudicate over the troika.
