New book, co-authored by Dr Mark Ellis and Ambassador David J Scheffer, charts 32 years of landmark rulings that built the modern system of international justice

Wednesday 21 October 2026

A new book by International Bar Association Executive Director, Dr Mark Ellis, and Council on Foreign Relations Senior Fellow, Ambassador David J Scheffer, offers an authoritative account of 32 years of modern international justice, tracing the landmark cases and legal precedents that have shaped accountability for atrocity crimes and the protection of human rights.

The IBA Special Project Fund allocated funding to the project so that the authors could undertake the research and writing required of it. The authors write: 'Without this funding, completing this book would not have been achieved.' They dedicate the book 'to those of the International Bar Association who have dedicated their professional lives to the pursuit of international justice before the modern atrocity crimes tribunals and the international and regional courts that in our time have enforced fundamental human rights and international criminal law.'

The Story of Modern International Justice, 1993-2025

The Story of Modern International Justice, 1993-2025, published by Springer, examines the evolution of international justice from the establishment of the International Criminal Tribunal for the former Yugoslavia, in 1993, to the contemporary system of international courts and tribunals, including the International Criminal Court (ICC) and the newly created Special Tribunal for the Crime of Aggression against Ukraine.

As well as detailing the jurisprudence of the ad hoc and hybrid tribunals and the ICC, the book examines the growing precision with which international law defines atrocity crimes − including genocide, crimes against humanity and war crimes − and traces the development of principles of individual criminal responsibility, from command responsibility to joint criminal enterprise.

A further focus is the jurisprudence of the International Court of Justice’s rulings on state responsibility, the emergence of new principles governing non-international armed conflicts and the role of the European, Inter-American and African human rights courts in enforcing the obligations of states to protect fundamental rights. Together, these developments illustrate the breadth of modern international justice, extending beyond criminal accountability to the wider international legal order and the protection of individuals.

Importantly, the authors devote a dedicated chapter to the critical role of defence counsel across the modern atrocity crimes tribunals. The chapter highlights the essential contribution of the defence to fair trial rights, due process and the integrity and legitimacy of international criminal proceedings.

By placing the human stories behind landmark judgments alongside the legal principles those decisions established, the book seeks to make complex jurisprudence accessible to both general readers as well as legal specialists. It offers practitioners, academics, judges, policymakers and students a resource for understanding not only how international justice has evolved, but also the legal foundations on which future developments will depend.

Dr Ellis said: ‘The story of modern international justice is ultimately a story of law being tested, interpreted and developed in response to some of humanity’s gravest crimes. The decisions examined in this book have helped establish enduring legal principles while exposing the practical and institutional challenges of securing accountability. By connecting the jurisprudence with the human experiences behind the cases, we hope to deepen understanding of what international justice has achieved and what must be sustained for the future.’

Ambassador Scheffer said: ‘Understanding the development of international justice is essential to understanding the responsibilities of the legal profession today. Over the past three decades, international courts and tribunals have helped define the law governing atrocity crimes, strengthen the principle of individual accountability and advance the protection of fundamental rights. This book brings those developments together, offering the legal community an important resource for examining the progress achieved, the principles established and the challenges that remain.’

Richard Goldstone, former Chief Prosecutor of the International Criminal Tribunals for the former Yugoslavia and Rwanda, wrote the book's foreward in which he states: 'The Story of Modern International Justice, 1993-2025 is timely and essential for a foundational understanding of what transpired during the post-Cold War era in an impressive number of judicial bodies [...] Never before in the history of humankind have so many leading perpetrators of atrocity crimes and governments responsible for gross violations of human rights have been held to account and international justice upheld and fortified [...] The foundation for international justice has been built, and there must never be any turning back.'

The book also considers the significance of the Special Tribunal for the Crime of Aggression against Ukraine within the continuing development of international justice. Its inclusion reflects the evolving institutional landscape and the ongoing effort to address accountability for serious violations of international law.

As debates continue over the enforcement of international law, the jurisdiction and effectiveness of international courts and the protection of civilians in armed conflict, a clear understanding of the jurisprudence accumulated since 1993 is particularly valuable. The book provides a foundation for informed discussion of these issues, helping the legal community assess the achievements of existing institutions and the challenges confronting the next generation of international justice.

The Story of Modern International Justice, 1993-2025, is published by Springer and is available in eBook and hardcover formats. Read more about the book here.

  4. The International Bar Association (IBA), the global voice of the legal profession, is the foremost organisation for international legal practitioners, bar associations and law societies. Established in 1947, shortly after the creation of the United Nations, with the aim of protecting and promoting the rule of law globally, it was born out of the conviction that an organisation made up of the world’s bar associations could contribute to global stability and peace through the administration of justice.

    The IBA acts as a connector, enabler and influencer, for fair practice and accountability worldwide. The IBA has collaborated on a broad range of ground-breaking, international projects with the United Nations, the European Parliament, the Council of Europe, The Commonwealth, the Organisation for Economic Co-operation and Development (OECD), the World Trade Organization, the International Monetary Fund and the World Bank, among others.
