The International Court of Justice announces that Belgium has officially joined South Africa’s lawsuit against Israel for genocide in Gaza, in a legal move based on Article 63 of the court’s statute.

The International Court of Justice (ICJ) announced today a significant legal and diplomatic development in the case brought by South Africa against Israel. The court confirmed that the Kingdom of Belgium has officially joined the lawsuit accusing the Israeli occupation of committing genocide in the Gaza Strip. This announcement strengthens the international legal front demanding accountability for Israel and adherence to international conventions.

Details of Belgian accession and Article 63

The court explained in its official statement that Belgium's accession was based on Article 63 of the Statute of the International Court of Justice. This article grants states party to any international treaty (in this case, the 1948 Convention on the Prevention and Punishment of the Crime of Genocide) the right to intervene in matters concerning the interpretation of the provisions of that treaty. Under this intervention, the interpretation adopted by the court in its final judgment will also be binding on Belgium, reflecting Brussels' commitment to upholding the outcomes of international justice.

Context of the lawsuit and historical background

The roots of this case date back to late 2023, when South Africa submitted a comprehensive dossier to the International Court of Justice accusing Israel of violating its obligations under the Genocide Convention during its ongoing war on the Gaza Strip. Since then, the Court has issued several provisional orders and measures requiring Israel to prevent any acts of genocide and ensure humanitarian access, a matter closely monitored by the states involved in the case.

European and international position

The Belgian move is a notable step within the European Union, as Belgium has distinguished itself with a more progressive stance in support of Palestinian rights compared to some other European countries. Brussels has repeatedly called for an immediate ceasefire and the protection of civilians, and has been among the voices demanding sanctions against settlers who perpetrate violence in the West Bank. This move aligns with a growing wave of European positions, with countries like Spain and Ireland having already taken similar diplomatic and legal steps reflecting growing unease with the continuation of the war and its catastrophic humanitarian consequences.

The importance of the event and its expected impact

Belgium's joining the case is particularly significant as it lends added weight to the issue from the heart of Europe, refuting the narrative that portrays the case as a conflict between the Global South and the West. Furthermore, the expanding number of countries joining the case increases the political, moral, and legal pressure on Israel, and places the international community before its responsibilities to protect the system of international humanitarian law, which is now under threat in light of the ongoing massacres in Gaza.
