International Residual Mechanism for Criminal Tribunals (IRMCT)

The International Residual Mechanism for Criminal Tribunals (the Mechanism) is a United Nations (UN) organization mandated to perform a number of essential functions previously carried out by the International Criminal Tribunal for Rwanda (ICTR) and the International Criminal Tribunal for the former Yugoslavia (ICTY).

The Mechanism has two branches: one in Arusha, United Republic of Tanzania, and one in The Hague. In carrying out its functions, including witness protection, preservation of archives, assistance to national jurisdictions, as well as conducting appeals, reviews and retrials of cases inherited from the two Tribunals, the Mechanism maintains the legacies of these two pioneering ad hoc international tribunals and strives to reflect best practices in the field of international criminal justice. Appeal proceedings in the ICTY-related cases of Radovan Karadžić and Ratko Mladić, as well as a retrial in the case of Jovica Stanišić and Franko Simatović, among other judicial matters, are currently ongoing at the Mechanism’s Hague branch. At the Arusha branch of the Mechanism, there is currently a review of the appeal judgement in the case of Augustin Ngirabatware underway.

At the Hague branch, the Mechanism is primarily concerned with tasks inherited from the ICTY. The ICTY was the first UN international criminal tribunal established to prosecute persons considered responsible for the most serious crimes that took place during the 1990s conflicts in the Balkans. Established in 1993, the ICTY irreversibly changed the landscape of international criminal and humanitarian law and has ushered in a new era where it is no longer a question that individuals who commit grave crimes should be held criminally responsible. The tribunal completed its mandate in December 2017, handing its remaining tasks to the Mechanism.

On 23 September 2018, The Mechanism will open its doors to the public.

Visiting the Mechanism will offer the opportunity to learn more about the work of the organization, the history of landmark cases on genocide, war crimes, and crimes against humanity, as well as the 1990s conflicts in the former Yugoslavia and Rwanda.
