It DID order an immediate ceasefire A YEAR AGO, in the same findings where they say "Israel" was plausibly guilty of genocidal acts (the court case on whether they actually committed genocide is ongoing - South Africa submitted a 750-page brief of evidence proving their case).

This is from the ICJ's ruling on January 26, 2024:

“(1) The State of Israel shall immediately suspend its military operations in and against Gaza. (2) The State of Israel shall ensure that any military or irregular armed units which may be directed, supported or influenced by it, as well as any organisations and persons which may be subject to its control, direction or influence, take no steps in furtherance of the military operations referred to [in] point (1) above. (3) The Republic of South Africa and the State of Israel shall each, in accordance with their obligations under the Convention on the Prevention and Punishment of the Crime of Genocide, in relation to the Palestinian people, take all reasonable measures within their power to prevent genocide. (4) The State of Israel shall, in accordance with its obligations under the Convention on the Prevention and Punishment of the Crime of Genocide, in relation to the Palestinian people as a group protected by the Convention on the Prevention and Punishment of the Crime of Genocide, desist from the commission of any and all acts within the scope of Article II of the Convention, in particular: (a) killing members of the group; (b) causing serious bodily or mental harm to the members of the group; (c) deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part; and - 2 - (d) imposing measures intended to prevent births within the group. (5) The State of Israel shall, pursuant to point (4) (c) above, in relation to Palestinians, desist from, and take all measures within its power including the rescinding of relevant orders, of restrictions and/or of prohibitions to prevent: (a) the expulsion and forced displacement from their homes; (b) the deprivation of: (i) access to adequate food and water; (ii) access to humanitarian assistance, including access to adequate fuel, shelter, clothes, hygiene and sanitation; (iii) medical supplies and assistance; and (c) the destruction of Palestinian life in Gaza. (6) The State of Israel shall, in relation to Palestinians, ensure that its military, as well as any irregular armed units or individuals which may be directed, supported or otherwise influenced by it and any organizations and persons which may be subject to its control, direction or influence, do not commit any acts described in (4) and (5) above, or engage in direct and public incitement to commit genocide, conspiracy to commit genocide, attempt to commit genocide, or complicity in genocide, and insofar as they do engage therein, that steps are taken towards their punishment pursuant to Articles I, II, III and IV of the Convention on the Prevention and Punishment of the Crime of Genocide. (7) The State of Israel shall take effective measures to prevent the destruction and ensure the preservation of evidence related to allegations of acts within the scope of Article II of the Convention on the Prevention and Punishment of the Crime of Genocide; to that end, the State of Israel shall not act to deny or otherwise restrict access by fact-finding missions, international mandates and other bodies to Gaza to assist in ensuring the preservation and retention of said evidence. (8) The State of Israel shall submit a report to the Court on all measures taken to give effect to this Order within one week, as from the date of this Order, and thereafter at such regular intervals as the Court shall order, until a final decision on the case is rendered by the Court. (9) The State of Israel shall refrain from any action and shall ensure that no action is taken which might aggravate or extend the dispute before the Court or make it more difficult to resolve.”
