CASE FILE · ICJ · 001  ONGOING
Application of the Convention on the Prevention and Punishment of the Crime of Genocide in the Gaza Strip (South Africa v. Israel)
International Court of Justice · Proceedings ongoing — Reply and Rejoinder ordered 21 May 2026
International Criminal Law
Parties
Republic of South Africa v. State of Israel
Legal Issues

Timeline

Case Summary

South Africa instituted proceedings alleging that Israel's conduct in Gaza breaches its obligations under the Genocide Convention, and has repeatedly returned to the Court to request further provisional measures as the situation on the ground evolved. The Court has issued successive provisional-measures orders directing Israel to take steps to prevent acts falling within the Convention and to ensure humanitarian access, without yet ruling on the merits. A large number of states — including Belgium, Brazil, Comoros, and Paraguay — have filed declarations of intervention, an unusually high number for a contentious case.

Strategic Significance

The case has become a central test of the Genocide Convention's provisional-measures machinery and of the scope for third-state intervention under Article 63. HILC's Legal Observatory tracks each order and pleading deadline as they are issued.

CASE FILE · ICJ · 002  ONGOING
Allegations of Genocide under the Convention on the Prevention and Punishment of the Crime of Genocide (Ukraine v. Russian Federation)
International Court of Justice · Proceedings ongoing — counter-claims ruled admissible, 2025
Use of Force
Parties
Ukraine v. Russian Federation
Legal Issues
Misuse of the Genocide Convention to justify use of force; jurisdiction under compromissory clauses; admissibility of counter-claims
Timeline
26 Feb 2022 — Application filed 16 Mar 2022 — Provisional measures ordered 2024 — Jurisdiction judgment (partial) 2025 — Russian counter-claims found admissible Reply/Rejoinder pleadings underway
Case Summary

Ukraine argued that Russia's invocation of genocide as a pretext for its 2022 invasion had no basis under the Genocide Convention. The Court found jurisdiction over most of Ukraine's claims in 2024, and has since ruled that counter-claims filed by the Russian Federation are admissible, directing both parties to complete a further round of written pleadings before the case can proceed to the merits.

Strategic Significance

A live test of the Genocide Convention as a jurisdictional hook for disputes concerning the use of force, and of how the Court manages counter-claims in a highly politicised case. Tracked in HILC's Legal Observatory as an active proceeding.

CASE FILE · ICJ · 003  ONGOING
Arbitral Award of 3 October 1899 (Guyana v. Venezuela)
International Court of Justice · Merits hearings concluded 11 May 2026 — judgment pending
Territorial & Boundary Disputes
Parties
Co-operative Republic of Guyana v. Bolivarian Republic of Venezuela
Legal Issues
Validity of the 1899 Arbitral Award fixing the Guyana–Venezuela boundary; sovereignty over the Essequibo region
Timeline
2018 — Application filed by Guyana 2020 — Jurisdiction upheld 4–11 May 2026 — Public hearings on the merits Judgment pending
Case Summary

Guyana asks the Court to confirm the validity and binding character of the 1899 Arbitral Award that established its boundary with Venezuela, and to declare Venezuela's continued reliance on the 1966 Geneva Agreement to reopen the frontier unlawful. Venezuela contests the Award's validity. The Court concluded merits hearings in May 2026 and has begun deliberation, with judgment expected in due course.

Strategic Significance

One of the most closely watched active territorial disputes before the Court, with direct implications for sovereignty over the oil-rich Essequibo region and for the stability of a colonial-era boundary award more than a century old.

CASE FILE · ICJ · 004  ONGOING
Application of the Convention on the Prevention and Punishment of the Crime of Genocide (The Gambia v. Myanmar)
International Court of Justice · Merits hearings concluded 29 January 2026 — judgment pending
International Criminal Law
Parties
Republic of The Gambia v. Republic of the Union of Myanmar (11 states intervening)
Legal Issues
State responsibility for genocide against the Rohingya; standing of a non-injured state under the Genocide Convention
Timeline
2019 — Application filed 2020 — Provisional measures ordered 2022 — Jurisdiction upheld 12–29 Jan 2026 — Merits hearings Judgment pending
Case Summary

The Gambia, acting without having suffered direct injury itself, brought proceedings alleging that Myanmar's military campaign against the Rohingya population breached the Genocide Convention. Eleven states, including Canada, the Netherlands, and the United Kingdom, have filed declarations of intervention. Merits hearings concluded in January 2026 and the Court is now deliberating.

Strategic Significance

A landmark test of erga omnes partes standing under the Genocide Convention — the principle that any contracting state may bring a claim even without direct injury — with the highest number of third-state interventions in the Court's history.

CASE FILE · ICC · 005  ON APPEAL
The Prosecutor v. Ali Muhammad Ali Abd-Al-Rahman ("Ali Kushayb")
International Criminal Court, Trial Chamber I · Convicted 6 October 2025 · Sentenced 9 December 2025 — appeal pending
International Criminal Law
Parties
The Prosecutor v. Ali Muhammad Ali Abd-Al-Rahman (Darfur, Sudan)
Legal Issues
Crimes against humanity and war crimes committed in Darfur (2003–2004); command and individual criminal responsibility
Timeline
2007 — Arrest warrant issued 9 Jun 2020 — Voluntary surrender to the ICC 5 Apr 2022 — Trial opens 6 Oct 2025 — Convicted on 27 counts 6 Nov 2025 — Defence files notice of appeal against conviction 9 Dec 2025 — Sentenced to 20 years' imprisonment
Case Summary

Trial Chamber I unanimously found Mr Abd-Al-Rahman guilty on 27 counts of crimes against humanity and war crimes committed in Darfur, Sudan, between August 2003 and April 2004, following a trial spanning 134 hearing days over two and a half years. The Defence filed notice of appeal against the conviction the following month. On 9 December 2025, the Chamber sentenced him to 20 years' imprisonment — below the Prosecution's request for a life sentence — with time in detention since his June 2020 surrender deducted from the term. Appeal proceedings against both conviction and sentence are ongoing.

Strategic Significance

One of the ICC's most significant convictions arising from the Darfur situation, and a live test of the Court's sentencing practice and appellate procedure. Directly relevant to the pending related case of Sudan v. United Arab Emirates before the ICJ.

CASE FILE · ICJ · 006  NEWLY FILED
Application of the Convention on the Prevention and Punishment of the Crime of Genocide in Sudan (Sudan v. United Arab Emirates)
International Court of Justice · Proceedings at an early stage
International Criminal Law
Parties
Republic of the Sudan v. United Arab Emirates
Legal Issues
Alleged complicity in genocide in Darfur through support to non-state armed actors; jurisdiction under the Genocide Convention
Timeline
2025 — Application filed by Sudan Preliminary procedural stage
Case Summary

Sudan has instituted proceedings against the United Arab Emirates alleging complicity in genocide in Darfur through alleged support to the Rapid Support Forces. The case is at an early procedural stage, and jurisdictional questions — including the effect of the UAE's reservation to the Genocide Convention's compromissory clause — are expected to be contested.

Strategic Significance

Raises novel questions on state responsibility for genocide committed by non-state actors receiving external support, and sits alongside the ICC's Abd-Al-Rahman conviction as part of the broader Darfur accountability docket that HILC's Legal Observatory is following closely.
