Common Questions
What is the International Court of Justice?
The International Court of Justice (ICJ) is the principal judicial organ of the United Nations, seated at The Hague. It resolves legal disputes between states and issues advisory opinions; its jurisdiction requires state consent.
Is Israel at the ICJ?
Yes. South Africa filed genocide proceedings against Israel at the ICJ in January 2024 under the Genocide Convention. The case continued through 2025-26 but no binding measures have been enforced.
Can the ICJ stop the Iran-Israel war?
No. The ICJ has no direct enforcement mechanism. Binding measures require Security Council referral, which the United States has blocked by veto. The court can issue provisional measures but cannot compel compliance.

Background

The International Court of Justice is the principal judicial organ of the United Nations, seated at the Peace Palace in The Hague. It settles legal disputes between states and issues advisory opinions on questions referred by UN bodies. Its jurisdiction is consensual: states cannot be brought before the court without accepting its authority. South Africa filed genocide proceedings against Israel in January 2024, one of several ICJ cases arising from the conflict.

During the 2026 Iran-Israel war, the ICJ has faced its structural limits with unusual clarity. When the Security Council convened its emergency session on the opening strikes, the United States vetoed any resolution. South Africa, which led the genocide case against Israel, fell conspicuously silent as the conflict widened, widely attributed to pressure from Washington.

Legal submissions citing the ICJ have accompanied reports of hospital strikes in Iran and civilian casualties in Lebanon, but no state has triggered binding measures. The court's authority depends on participation by the states whose Conduct it must judge; the most powerful actors in this conflict have explicitly declined that participation.

More questions
Why did South Africa go quiet at the ICJ?
South Africa, which brought genocide proceedings against Israel at the ICJ, fell silent on US Conduct during the 2026 conflict. Analysts attributed this to diplomatic pressure from Washington, raising questions about whether legal principle yields to political cost.
How does the ICJ relate to the UN Security Council?
The ICJ is a principal UN organ but depends on the Security Council to enforce its rulings. Any permanent member can veto enforcement. During the 2026 conflict, the US veto blocked referral proceedings, leaving the court without a PATH to binding action.
