The International Criminal Tribunal for the former Yugoslavia (ICTY) was an ad hoc court of the United Nations that was established to prosecute the war crimes that had been committed during the Yugoslav Wars and to try their perpetrators. The tribunal was located in The Hague, Netherlands, and operated between 1993 and 2017.
It was established by Resolution 827 of the United Nations Security Council, which was passed on 25 May 1993. It had jurisdiction over four clusters of crimes committed on the territory of the former Yugoslavia since 1991: grave breaches of the Geneva Conventions, violations of the laws or customs of war, genocide, and crimes against humanity. The maximum sentence that it could impose was life imprisonment. Various countries signed agreements with the United Nations to carry out custodial sentences.
A total of 161 persons were indicted; the final indictments were issued in December 2004, the last of which were confirmed and unsealed in the spring of 2005. The final fugitive, Goran Hadžić, was arrested on 20 July 2011. The final judgment was issued on 29 November 2017 and the institution formally ceased to exist on 31 December 2017.
Residual functions of the ICTY, including the oversight of sentences and consideration of any appeal proceedings initiated since 1 July 2013, are under the jurisdiction of a successor body, the International Residual Mechanism for Criminal Tribunals (IRMCT).
United Nations Security Council Resolution 808 of 22 February 1993 decided that an "international tribunal shall be established for the prosecution of persons responsible for serious violations of international humanitarian law committed in the territory of the former Yugoslavia since 1991", and called on the Secretary-General to "submit for consideration by the Council ... a report on all aspects of this matter, including specific proposals and where appropriate options ... taking into account suggestions put forward in this regard by Member States".
The court was originally proposed by German Foreign Minister Klaus Kinkel.
Resolution 827 of 25 May 1993 approved the S/25704 report of the secretary-general and adopted the Statute of the International Tribunal annexed to it, formally creating the ICTY. It was to have jurisdiction over four clusters of crimes committed on the territory of the former SFR Yugoslavia since 1991:
Grave breaches of the Geneva Conventions
Violations of the laws or customs of war
The maximum sentence the ICTY could impose for these crimes was life imprisonment.
In 1993 the internal infrastructure of the ICTY was built. 17 states had signed an agreement with the ICTY to carry out custodial sentences.
1993–1994: In the first year of its existence, the tribunal laid the foundations for its existence as a judicial organ. It established the legal framework for its operations by adopting the rules of procedure and evidence, as well as its rules of detention and directive for the assignment of defence counsel. Together, these rules established a legal aid system for the tribunal. As the ICTY was a part of the United Nations and was the first international court for criminal justice, the development of a juridical infrastructure was considered quite a challenge. However, after the first year, the first ICTY judges had drafted and adopted all the rules for court proceedings.
1994–1995: The ICTY established its offices within the Aegon Insurance Building in The Hague (which was, at the time, still partially in use by Aegon) and detention facilities in Scheveningen in The Hague (the Netherlands). The ICTY hired many staff members and by July 1994, the Office of the Prosecutor had sufficient staff to begin field investigations. By November 1994, the first indictments were presented to the court and confirmed, and in 1995, the staff numbered over 200, from all over the world.
In 1994 the first indictment was issued against the Bosnian-Serb concentration camp commander Dragan Nikolić. This was followed on 13 February 1995 by two indictments comprising 21 individuals which were issued against a group of 21 Bosnian-Serbs charged with committing atrocities against Muslim and Croat civilian prisoners. While the war in the former Yugoslavia was still raging, the ICTY prosecutors showed that an international court was viable. However, no accused was arrested.
The court confirmed eight indictments against 46 defendants and issued arrest warrants. Bosnian Serb indictee Duško Tadić became the subject of the tribunal's first trial. Tadić was arrested by German police in Munich in 1994 for his alleged actions in the Prijedor region in Bosnia-Herzegovina (especially his actions in the Omarska, Trnopolje and Keraterm detention camps). He made his first appearance before the ICTY Trial Chamber on 26 April 1995, and pleaded not guilty to all of the charges in the indictment.
1995–1996: Between June 1995 and June 1996, 10 public indictments were confirmed against a total of 33 people. Six of them were transferred in the tribunal's detention unit. In addition to Duško Tadic, by June 1996 the tribunal had Tihomir Blaškić, Dražen Erdemović, Zejnil Delalić, Zdravko Mucić, Esad Landžo and Hazim Delić in custody. Erdemović became the first person to enter a guilty plea before the tribunal's court. Between 1995 and 1996, the ICTY dealt with miscellaneous cases involving several detainees, which never reached the trial stage.
The tribunal indicted 161 individuals between 1997 and 2004 and completed proceedings with them as follows:
111 had trials completed by the ICTY:
