The International Court of Justice (ICJ) has become the stage for a significant international legal confrontation as multiple nations formally intervened in South Africa’s genocide case against Israel. The United States submitted a declaration on Thursday that explicitly defends Israel against allegations of committing genocide in Gaza, marking a notable development in the proceedings.
According to the court’s Friday press release, the US filing was accompanied by separate interventions from Namibia, Hungary, and Fiji. These submissions were made under Article 63 of the ICJ statute, which permits countries that are parties to a disputed treaty to present their interpretation of that treaty. Iceland and the Netherlands also filed declarations under the same provision on Thursday.
The case originated in December 2023 when South Africa accused Israel of violating the Genocide Convention through its military operations in Gaza following the October 7 Hamas-led attacks. Pretoria’s case contends that Israel’s actions—including mass casualties, infrastructure destruction, and creating conditions threatening Palestinian survival—constitute genocide, which Israel denies, maintaining its military campaign is justified self-defense.
The US intervention stands apart for its direct rebuttal of South Africa’s allegations. Washington’s declaration argues that accusations of Israeli genocide are “false” and urges the court to apply a stringent legal threshold when assessing genocidal intent. The submission emphasizes that genocide requires clear proof of specific intent to destroy a protected group, asserting that such intent should only be inferred when it represents the only reasonable explanation for observed conduct.
The US further contends that the exceptional gravity of genocide demands that the court be fully convinced before making such a determination, noting that civilian casualties and destruction during conflict alone do not demonstrate genocidal intent. Washington warned that lowering the standard risked broadening the term’s application beyond its original meaning and could misuse the Genocide Convention to bring extraneous disputes before the court.
While Article 63 interventions are technically limited to treaty interpretation, the US declaration explicitly challenges South Africa’s allegations. Hungary and Fiji’s submissions similarly advance legal arguments aligning with Israel’s position, calling for narrow interpretations of genocide and high evidentiary thresholds.
In contrast, Namibia’s declaration advocates for a broader interpretation of the Genocide Convention, emphasizing how genocidal intent may be inferred from patterns of conduct and cumulative evidence. Namibia argues that acts including denial of humanitarian aid, repeated displacement, and deprivation of basic necessities could constitute deliberately inflicting conditions intended to destroy a protected group. Their submission also stresses that genocide can occur through omissions, such as refusing life-saving humanitarian assistance to civilians under state control.
These latest filings expand the growing list of states seeking to intervene, which now includes 22 nations—an unusually high number for ICJ proceedings. Since April 2024, countries including Colombia, Libya, Mexico, Palestine, Spain, Turkey, Chile, the Maldives, Bolivia, Ireland, Cuba, Belize, Brazil, the Comoros, Belgium, and Paraguay have submitted interventions. Palestine and Belize have additionally sought to participate under Article 62, which allows states with potentially affected legal interests to join proceedings.
The ICJ has already issued legally binding provisional measures ordering Israel to prevent acts that could violate the Genocide Convention and permit humanitarian aid into Gaza, though Israel has repeatedly ignored these orders. A final ruling on whether Israel breached the Convention is expected by 2028, though timing may vary based on hearing lengths and party compliance with deadlines.
On Thursday, Israel was scheduled to submit its counter-memorial responding to South Africa’s accusations after several deadline extensions, though the court had not announced the filing as of the latest reports.
The humanitarian situation in Gaza remains dire, with reports indicating over 70,000 Palestinian casualties—mostly women and children—during Israel’s military operations. Most of Gaza’s homes, hospitals, schools, and infrastructure have been destroyed, rendering the enclave largely uninhabitable for its 2.3 million civilians.
A September UN commission of inquiry concluded that Israel has committed genocide in Gaza since October 2023. The report’s authors, including legal experts Navi Pillay and Chris Sidoti, indicated to Middle East Eye that their analysis used evidence and methodology similar to what the ICJ will employ in its proceedings.
