Genocide Cases at the ICJ: Bosnia to Gaza Now

How the Court has addressed genocide allegations, from Bosnia to Myanmar to the Gaza proceedings.

The Genocide Convention and ICJ Jurisdiction

Article IX of the 1948 Genocide Convention gives the ICJ jurisdiction over disputes between states relating to the interpretation, application, or fulfilment of the Convention. This compromissory clause has been the basis for several of the ICJ's most important and politically charged cases. Because more than 150 states are parties to the Convention, the jurisdictional reach is broad.

Genocide cases at the ICJ are fundamentally different from genocide prosecutions at the ICC. The ICJ determines whether a state has violated its obligations under the Convention, not whether individuals are criminally responsible. The Court can find state responsibility for genocide, order reparations, and indicate provisional measures to prevent ongoing genocide.

Bosnia v. Serbia (2007)

The first genocide case decided on the merits was Bosnia v. Serbia. Bosnia alleged that Serbia was responsible for genocide during the 1992-1995 Bosnian War, including the Srebrenica massacre. The Court found that the Srebrenica massacre constituted genocide but that Serbia had not committed genocide directly. However, Serbia had violated its obligation to prevent genocide and to punish those responsible by failing to cooperate with the ICTY.

The judgment was controversial. Critics argued the Court set the evidentiary bar too high for state responsibility, requiring proof of specific intent (dolus specialis) at the state level. The decision that only Srebrenica, and not the broader ethnic cleansing campaign, constituted genocide disappointed many Bosnians. But the finding that a state had violated its obligation to prevent genocide was unprecedented.

Recent Genocide Cases

In 2019, The Gambia filed a case against Myanmar alleging genocide against the Rohingya. The case was notable because The Gambia, a small West African state, brought the claim on behalf of the broader international community using the erga omnes partes standing that the Convention grants to all parties. In January 2020, the Court indicated provisional measures ordering Myanmar to protect the Rohingya.

In December 2023, South Africa filed a case against Israel alleging genocide in Gaza. The Court's January 2024 provisional measures order became one of the most discussed ICJ decisions in history. The Court found it plausible that some rights under the Genocide Convention were at risk and ordered Israel to take measures to prevent genocide, though it did not order a ceasefire. The case remains pending and is shaping global debate about international humanitarian law and accountability.

Erga Omnes Partes Standing

The ICJ has recognized that obligations under the Genocide Convention are owed to all states parties (erga omnes partes), meaning any party can bring a case alleging a violation even if it is not directly injured. This is how The Gambia could bring a case about the Rohingya in Myanmar and South Africa could bring a case about Palestinians in Gaza. It significantly expands access to the Court for accountability purposes.

The Genocide Docket at a Glance

Comparing the Court's genocide cases side by side shows what changed over time — especially the shift toward erga omnes partes standing and the growing use of provisional measures.

Case	Filed / Decided	Standing basis	Key outcome
Bosnia v. Serbia	Decided 2007	Directly injured state	Srebrenica was genocide; Serbia breached duty to prevent, not commission
Croatia v. Serbia	Decided 2015	Directly injured states	Both claim and counter-claim of genocide rejected
The Gambia v. Myanmar	Filed 2019	Erga omnes partes	Provisional measures (2020) to protect the Rohingya
South Africa v. Israel	Filed 2023	Erga omnes partes	Provisional measures (2024); merits pending

Worked example — proving state intent. Bosnia v. Serbia is the template for how hard it is to establish state responsibility. To find a state itself committed genocide, the Court requires proof of dolus specialis — specific intent to destroy a protected group in whole or in part — attributable to the state, to a high standard of certainty. Serbia's undisputed involvement in the war was not enough; the Court could attribute the Srebrenica killings to Bosnian Serb forces but not the requisite state intent to Belgrade. The fallback was the duty to prevent: a state that knew or should have known of a serious risk of genocide and failed to use its influence to stop it is responsible for that failure. This two-tier structure — commission (very hard) versus prevention (more attainable) — explains most genocide-case outcomes.
