Why does the crime of aggression matter for Ukraine and international peace?

How can a Special Tribunal hold Russian leaders accountable? In this episode of Lawyering Peace, Ukrainian international lawyer Dr. Gaiane Nuridzhanian joins the conversation to explain the case for a Special Tribunal for the Crime of Aggression against Ukraine.

Dr. Nuridzhanian walks us through the evolution of the debate surrounding the crime of aggression, and presents a treaty-based tribunal—supported by Ukraine and the Council of Europe—as a legally sound, politically feasible alternative.

The conversation explores legal and strategic questions around the establishment of such a tribunal, from head-of-state immunity and trials in absentia to the inclusion of victims and its implications for future peace negotiations.

In a moment when the rules-based international legal order is under threat, our conversation with Dr. Nuridzhanian reminds us why prosecuting Russia’s war of aggression is critical not just for Ukraine, but for global accountability and future conflict prevention. Tune in for a timely discussion on justice, accountability, and international legal innovation.

Is the system of international law today capable of effectively achieving justice and accountability for Ukraine?

How can accountability be made central to a future peace process—and not sacrificed for short-term political gain?

In the latest episode of the Lawyering Peace podcast, Oleksandra Matviichuk, Nobel Peace Laureate and Head of the Center for Civil Liberties, joins Dr. Paul R. Williams to discuss the pursuit of justice and accountability for atrocity crimes committed during Russia’s war of aggression.

Matviichuk outlines a comprehensive vision of justice—from prosecution and reparations to public truth-telling and recognition—and highlights the need for a Special Tribunal for the Crime of Aggression.

She warns against the sidelining of justice in peace negotiations, and calls for reform of the global legal order to adequately address impunity for international crimes. At the heart of her message is a powerful reminder: even when institutions falter, people have the power to shape history.

How has Russia used conflict-related sexual violence as a tool in its war of aggression?

What does meaningful justice for survivors of Russia’s conflict-related sexual violence look like? In this episode, Dr. Kateryna Busol joins Dr. Paul R. Williams on the Lawyering Peace podcast.

Dr. Busol explores the widespread and systematic use of conflict-related sexual violence (CRSV) by Russian forces in Ukraine. Dr. Busol explores how societal norms and toxic gender hierarchies in Russia fuel the use of CRSV as a weapon of Russian aggression, and the impact on both survivors and Ukrainian society at large.

She thoughtfully explains the challenges that survivors face in seeking justice, and the ways in which female victims have spearheaded the effort to advocate for male survivors of CRSV.

Dr. Busol stresses the need for survivor-centered, gender-sensitive approaches to accountability, emphasizing that reparations should include not just financial compensation but also rehabilitation, symbolic recognition, and guarantees of non-repetition.

This discussion underscores the intersection of CRSV with broader peace and justice issues, highlighting the importance of a meaningful and holistic justice process. Dr. Busol reminds us that addressing such violence is key to achieving a sustainable, survivor-centered peace.

How can Ukraine protect its territorial integrity in peace negotiations?

What role does the international community play in ensuring that no territory is lost? In this episode, Ambassador Elayne Whyte Gómez of Costa Rica and member of PILPG’s Circle of Former Ambassadors, and Professor Kushtrim Istrefi of Utrecht University and PILPG Senior Peace Fellow, join the conversation.

Ambassador Gómez and Professor Istrefi explore questions relating to Ukraine’s territorial integrity and the central importance of maintaining its rightful territorial claims during peace negotiations.

Negotiations to end Russia’s war have gained momentum in recent weeks. However, the question of Ukraine’s occupied territories and their future status remains a key concern for Ukraine and its allies as they consider what a future peace agreement may look like.

Russia continues to deny the validity of Ukraine’s rightful claim to its internationally recognized borders as of 1991, and seeks to portray its war of aggression as . However, as our guests demonstrate, Ukraine’s claim is firmly rooted in international law. Our experts discuss the risks of unresolved territorial disputes, the role of international law, and outline practical tools at Ukraine and its allies’ disposal to maintain Ukraine’s territorial claim during peace negotiations, including international administration and non-recognition strategies.

In a war which Russia consistently claims is based on self-defense and self-determination, our guests remind us that it is crucial to keep focus on the reality of Russia’s invasion as a war of aggression against the territorial sovereignty of Ukraine. Tune in for a compelling discussion on how Ukraine can push back against historical distortions, build alliances, and secure its future.

In this episode of Lawyering Peace, we are joined by Mykola Stetsenko, President of the Ukrainian Bar Association, who speaks about the pivotal role of private sector investment in Ukraine’s post-war reconstruction. The conversation explores key industries primed for growth—agriculture, manufacturing, IT, energy, and logistics—as well as investment mechanisms such as public-private partnerships and industrial parks.

Stetsenko explains how Ukraine’s natural resource ownership model simplifies foreign investment, the government’s push to modernize industries rather than merely rebuild, and efforts to align with EU regulations. He also addresses common misconceptions about investing in Ukraine, the challenge of balancing economic development with environmental sustainability, and the policies designed to attract foreign investors by streamlining bureaucracy and fostering innovation.

With major multinationals already operating in the country and digital transformation reducing red tape, Ukraine presents compelling opportunities for forward-thinking investors. Tune in to discover how businesses can play a vital role in post-war recovery while seizing high-impact investment opportunities.

Our second guest in our Series on Prospects for Peace in Ukraine is Dr. Ivan Horodyskyy, Vice-President of the Ukrainian Bar Association and Director and Cofounder of the Dnistrianskyi Centre for Law and Politics, where he manages projects related to compensation for Ukrainians for damages caused by Russian aggression.

Since Russia’s 2022 full-scale invasion, Ukraine and its allies have called for Russia to bear responsibility for its illegal acts, including making reparation, to widespread international support. In this episode, we discuss the question of reparations for Russia’s extensive war damage in Ukraine, as well as the closely related issues of frozen Russian assets and postwar reconstruction.

Significant challenges lie ahead in negotiating reparations for Ukraine: what might a compensation mechanism look like, how should reparations be funded, what role should Russia’s frozen assets play, and how can Russia be made to pay? With Ivan, we explore these questions and more and consider the challenges and strategies for the future negotiation of reparations for Ukraine. -------------------------- Ukraine and its allies stand at a critical juncture as they pursue a just and lasting peace and an end to Russia’s war of aggression.
