Judicial Engagement
- Introduction
- Former International Tribunal Judges
Korean judges have played significant roles in international criminal tribunals.
Former Judge KWON O-gon served on the International Criminal Tribunal for the former Yugoslavia (ICTY) from 2001 to 2016. He was also President of the Assembly of States Parties to the Rome Statute of the ICC and continues to hold several positions at the Court.
Former President SONG Sang-hyun served as both judge and President of the International Criminal Court (ICC) for 12 years. Judge Chung Chang-ho served at the ICC from 2015 to 2025, following his work at the Extraordinary Chambers in the Courts of Cambodia (ECCC). Judge BAIK Kang Jin served as an International Judge of the ECCC Pre-Trial Chamber from 2015 to 2021 and now presides in the High Court of Korea.
Beyond their service on tribunals, Korean judges have actively participated in international legal communities. In 2008, for example, judges were sent to the ICTY as research judges to gain practical experience in international criminal proceedings. Since 2010, these placements have included secondments to the Hague Conference on Private International Law (HCCH).
Secondments to diplomatic missions have continued for several years. Judges have served as legal counselors at Korean embassies in the United States and Austria, as well as at the Permanent Mission of the Republic of Korea to the United Nations in the Netherlands.
In 2026, the secondment has extended to include international organizations such as the Organization for Economic Cooperation and Development (OECD) and the International Institute for the Unification of Private Law (UNIDROIT). These assignments have significantly enhanced the expertise and global engagement of the Korean judiciary, strengthening its competitiveness.

In November 2001, former Judge KWON O-gon, then presiding judge of the Daegu High Court, was elected as a permanent judge of the International Criminal Tribunal for the former Yugoslavia (ICTY). He became the first Korean judge to serve on an international tribunal. From 2008 to 2011, he also served as Vice President of the ICTY. The tribunal, the first of its kind since the Nuremberg Trials and the Tokyo War Crimes Trials, was established to prosecute serious crimes such as genocide and crimes against humanity committed in the territory of the former Yugoslavia.
From 2002 to 2006, Judge Kwon sat on the trial of Slobodan Milosevic, former president of the Republic of Serbia and the Federal Republic of Yugoslavia, who faced charges including forced migration, rape, and genocide. Beginning in 2009, he presided over the trial of Radovan Karadzic, the former Bosnian Serb leader held responsible for commanding the genocide of Croats and Muslims during the Bosnian Civil War. The Karadzic case became one of the largest and most complex in the ICTY’s history, involving 600 witnesses, 11,500 exhibits, and more than 300,000 pages of disclosed material.
Judge Kwon retired from the ICTY on March 31, 2016. During his tenure, he played a crucial role in advancing international justice and promoting global peace. Through the ICTY trials, he contributed to the development of both substantive and procedural international customary law. At a time when no precedents existed for international criminal trials, Judge Kwon was instrumental in bringing to justice individuals responsible for crimes against humanity and war crimes.
Former Judge CHUNG Chang-ho, then the presiding judge of the Busan High Court, served as a United Nations judge at the Extraordinary Chambers in the Courts of Cambodia (ECCC) from August 2011 to February 2015. During his tenure, he played a significant role in the ECCC’s efforts to deliver justice both internationally and within Cambodia by prosecuting crimes against humanity committed by the leaders of the Khmer Rouge.
After his esteemed service at the ECCC, Judge Chung was elected to the International Criminal Court (ICC) during the 13th Assembly of State Parties, held at United Nations Headquarters in New York in December 2014. His appointment made him the second Korean judge to serve at the ICC, following former ICC President Song Sang-hyun. The ICC is the first permanent international tribunal established to prosecute genocide, crimes against humanity, and war crimes.
Judge Chung's nine-year term at the ICC began in March 2015 and concluded in 2024. Throughout this period, he played an invaluable role in the Court’s work and advancing the international standing of the Korean judiciary.
Presiding Judge BAIK Kang-jin of Seoul High Court was appointed as a United Nations judge to the Extraordinary Chambers in the Courts of Cambodia (ECCC) in July 2015, succeeding Judge CHUNG Chang-ho. The ECCC, established in 2005 by a bilateral agreement between the United Nations and Cambodia, was mandated to prosecute crimes such as genocide committed under the Khmer Rouge regime from April 1975 to January 1979. Judge Baik served on the Pre-Trial Chamber, which settles disputes arising during investigations at the ECCC, as part of the tribunal’s two-instance system.
During his tenure, Judge Baik made significant contributions to the advancement of international criminal justice and further demonstrated the excellence of Korean judges on the global stage.
