The International Criminal Tribunal for the former Yugoslavia (ICTY) was established by UN Security Council Resolution 827 (1993) to prosecute serious violations of international humanitarian law committed in the territory of the former Yugoslavia since 1991. Seated in The Hague, it operated until its formal closure on 31 December 2017, with residual functions transferred to the International Residual Mechanism for Criminal Tribunals (IRMCT). Over its lifetime, the ICTY indicted 161 individuals and concluded proceedings against all of them.
Its jurisprudence is widely cited as foundational for contemporary international criminal law. Key doctrinal contributions include:
- Tadić (1995 Appeals Chamber Decision on Jurisdiction): clarified the definition of "armed conflict," extended individual criminal responsibility to violations committed in non-international armed conflicts, and articulated the "overall control" test for attributing the conduct of armed groups to a state.
- Furundžija (1998) and Kunarac et al. (2001): developed the legal definition of rape and recognised sexual violence as a form of torture and a crime against humanity.
- Krstić (2004 Appeals Judgement): confirmed that the Srebrenica massacre of July 1995 constituted genocide, and refined the mens rea standard for aiding and abetting genocide.
- Tadić (1999 Appeals Judgement): elaborated the doctrine of Joint Criminal Enterprise (JCE) as a mode of liability, later adopted and debated in other tribunals.
- Blaškić and Galić: developed standards on command responsibility and on the war crime of terrorising a civilian population.
ICTY jurisprudence directly influenced the Rome Statute of the International Criminal Court, the Statute of the ICTR, hybrid tribunals (Sierra Leone, Cambodia, Kosovo Specialist Chambers), and domestic war crimes prosecutions in the Western Balkans. It is also frequently invoked in ICJ proceedings, notably Bosnia and Herzegovina v. Serbia and Montenegro (2007), where the ICJ relied on ICTY findings regarding Srebrenica.
Example
In its 2004 Krstić Appeals Judgement, the ICTY confirmed that the killings of Bosniak men and boys at Srebrenica in July 1995 constituted genocide, a finding later relied upon by the ICJ in its 2007 ruling on Bosnia v. Serbia.
