Extraordinary Chambers in the Courts of Cambodia (ECCC)

Establishment

On 21 June 1997 Cambodia's co-prime ministers sent a letter requesting UN assistance to bring to justice those responsible for the genocide and crimes against humanity committed during Khmer Rouge rule (1975–1979). An agreement between the Royal Government of Cambodia and the United Nations was signed on 6 June 2003, endorsed by the UN General Assembly in resolution 57/228 and entered into force on 29 April 2005. Its immediate legal basis was Cambodia's Law on the Establishment of the ECCC of 10 August 2001, amended on 27 October 2004. The Chambers were formally established on 18 January 2006, and the first trial hearings, of Kaing Guek Eav ('Duch'), began on 17 September 2009.

Jurisdiction

The ECCC's temporal jurisdiction covers 17 April 1975 to 6 January 1979; during that period an estimated 1.7 million or almost two million people died under Democratic Kampuchea. Its personal jurisdiction covered two categories: senior leaders of Democratic Kampuchea most responsible for serious violations of Cambodian penal law, international humanitarian law and custom and recognized international conventions, and non-senior leaders most responsible for such crimes. Whether a person was 'senior' or 'most responsible' was a policy decision within the sole discretion of the Co-Prosecutors and Co-Investigating Judges.

Subject-matter jurisdiction covered crimes under the Cambodian 1956 Penal Code (homicide, torture, religious persecution), genocide under the 1948 Genocide Convention, crimes against humanity (murder, extermination, enslavement, deportation, imprisonment, torture, persecutions on political, racial and religious grounds, other inhumane acts), grave breaches of the 1949 Geneva Conventions, destruction of cultural property during armed conflict under the 1954 Hague Convention, and crimes against internationally protected persons under the 1961 Vienna Convention on Diplomatic Relations.

Structure and trials

The Pre-Trial Chamber and the Trial Chamber were composed of three Cambodian and two international judges, while the Supreme Court Chamber had four Cambodian and three international judges; international judges were appointed by Cambodia's Supreme Council of the Magistracy from nominees submitted by the UN Secretary-General. The ECCC also comprised the Office of the Co-Prosecutors, the Office of Co-Investigating Judges, a Defence Support Section and a Victims Support Section, with victims able to participate as civil parties seeking reparations.

Five people were indicted for genocide, crimes against humanity and/or war crimes, and three were convicted, all sentenced to life imprisonment. Kaing Guek Eav ('Duch', Case 001) was convicted on 26 July 2010, with his sentence raised to life on appeal. Nuon Chea and Khieu Samphan were convicted on 7 August 2014 (Case 002/01) and on 16 November 2018 (Case 002/02) of genocide against the Vietnamese and, for Nuon Chea, the Cham. The court could not impose the death penalty. Nuon Chea died on 4 August 2019 while appealing his genocide conviction, and on 22 November 2019 the Supreme Court Chamber held that his death did not vacate the trial judgment against him.

Khieu Samphan's appeal against his genocide conviction was rejected on 22 September 2022, with the guilty verdicts of genocide, crimes against humanity and grave breaches of the Geneva Conventions confirmed. This Supreme Court Chamber judgment was the ECCC's final substantive judgment, and on 23 December 2022 the court published the full written judgment, closing Case 002/02, its third and last trial. Wikipedia's narrative states that with the denial of Khieu Samphan's appeal and no other living senior Khmer Rouge members to indict, the tribunal concluded in December 2022 with three convictions in all.

Cases 003 and 004, criticism

Cases 003 (Meas Muth) and 004 (Yim Tith) did not reach trial. National and international Co-Investigating Judges issued conflicting closing orders (18 November 2018 and 28 June 2019), the Pre-Trial Chamber delivered opposing considerations (7 April 2021 and 17 September 2021), and in December 2021 the Supreme Court Chamber terminated proceedings against Meas Muth. International judges noted the continued absence of genuine prosecutorial effort and Cambodia's obligation, as a Genocide Convention state party, to prosecute the defendants should the ECCC not proceed further. Further criticism concerned alleged reluctance by the Cambodian government to try Khmer Rouge officials who switched alliances, financial costs ($173.3 million between 2006 and 2012, of which Cambodia contributed $42.1 million and the UN $131.2 million; over $200 million by 2014 with only one completed case), and rejections of victim applications, prompting the Open Society Justice Initiative to call for a UN investigation.

Residual phase

In December 2021 the Addendum to the UN–RGC Agreement on the Transitional Arrangements and the Completion of Work of the Extraordinary Chambers entered into force, conferring residual functions on the ECCC: revision proceedings, victim and witness protection, sanctioning interference with justice, supervision of sentence enforcement, judicial archives management, document access, public information, and monitoring enforcement of reparations. The residual phase commenced on 1 January 2023; Cambodia's residual mandate was originally scheduled to conclude later and has been extended, and Cambodia has proposed a successor national institution. The court was not dissolved, which distinguishes the end of judicial proceedings from a 'dissolved 2022' label.
