It was submitted to the court after the UN General Assembly resolution A/RES/77/247 was approved by a majority vote of 98 approved vs. 17 against and 52 absent. Here is a summary: https://en.wikipedia.org/wiki/Legal_consequences_arising_fro...
This link contains all written and spoken testimonies, as well as related documents and news from the UN. In it you will find several examples of international humanitarian law broken by Israel without consequences. You will find several UN resolutions ignored by Israel without consequences. This case seeks to establish which consequences Israel should face from decades of this behavior. The ICJ accepted this case, and proclaims jurisdiction.
During the oral testimonies you will find statements and conclusions such as this from South Africa:
> The available evidence indicates that Israel is responsible for inhuman acts which fall within the ambit of Article 2(a), (c), (d) and (f) of the Apartheid Convention. [1] (Paragraph 115)
Here is another example from the same oral testimony:
> The establishment of Israeli settlements in the Israeli-occupied territories is considered as illegal by the international community as they are in violation of Article 49 of the Fourth Geneva Convention. Paragraph 6 of Article 49 of the Fourth Geneva Convention provides that “the Occupying Power shall not deport or transfer parts of its own civilian population into the territory it occupies”. t therefore follows that any legislation authorising settlements or the extension of settlements “adopted by Israel to facilitate or set up settlements would be in violation of Article 43
I gave you this link because it is full of legal experts from all over the world citing humanitarian law and explaining how Israel is breaking them. This case would have been ongoing today even without Oct 7 and without the Gaza genocide. This case and the number of written and oral testimonies, and the content of these testimonies, is proof that the world is fed up with Israel’s behavior towards the Palestinians.
