New #ICJ case: DRC accuses Rwanda of violating the Genocide Convention, CERD, CEDAW, and CAT. We've been down this road before; the ICJ dismissed another DRC v Rwanda case back in 2006 for lack of jurisdiction. 20 years later, have those problems been overcome? www.icj-cij.org/sites/defaul...

The #ICJ has fixed exceedingly long time-limits for the second round of written pleadings in South Africa v Israel (SA's reply is due 22 Nov 2027, ISR's rejoinder is due 22 May 2029). This likely means that no judgment on the merits should be expected until late 2030 at the absolute earliest.

I spoke with @aljazeera.com this week about the latest developments in #Gaza, which increasingly seem overshadowed by the Iran war and Israel's campaign in Lebanon. www.aljazeera.com/news/2026/5/...

Just what are Israel’s long-term plans for Gaza?
Despite an apparent ceasefire, Israel's leaders continue to hint at annexation and ethnic cleansing.

One reason why the opening of the #ICJ hearing in #TheGambia v #Myanmar this morning is remarkable: When The Gambia filed the case in 2019, there was no guarantee it would be willing to stay the course and see the case through (arguably a heightened risk for cases brought by non-injured states).

Amidst the unending horrors of #Gaza, I spoke to @davidmacredmond.bsky.social at @thejournal.ie about complicity in genocide & the distinct obligation of states to prevent genocide. There is no question that the 'serious risk' threshold (which triggers that duty) was met in Gaza a long time ago.

One point to clarify about #SouthAfrica v #Israel at the #ICJ. The case is not really moving at a slower pace than other ICJ cases. It’s typical for ICJ cases to last 4-5 years & I don’t see any particular effort on the ICJ’s part to slow things down further due to nature of this case.

but don't forget: While the International Court of Justice answered legal questions, climate change and its consequences are everything but legal. International (environmental) law is a tool, not the answer. The most important passage of the advisory opinion are these non-legal statements below 👇
456. Before concluding, the Court recalls that it has been suggested that these advisory proceedings are unlike any that have previously come before the Court. At the same time, as the Court concluded earlier, the questions put to it by the General Assembly are legal ones (see paragraph 40), and the Court, as a court of law, can do no more than address the questions put to it through and within the limits of its judicial function; this is the Court’s assigned role in the international legal order. However, the questions posed by the General Assembly represent more than a legal problem: they concern an existential problem of planetary proportions that imperils all forms of life and the very health of our planet. International law, whose authority has been invoked by the General Assembly, has an important but ultimately limited role in resolving this problem. A complete solution to this daunting, and self-inflicted, problem requires the contribution of all fields of human knowledge, whether law, science, economics or any other. Above all, a lasting and satisfactory solution requires human will and wisdom — at the individual, social and political levels — to change our habits, comforts and current way of life in order to secure a future for

- 130 -

ourselves and those who are yet to come. Through this Opinion, the Court participates in the activities of the United Nations and the international community represented in that body, with the hope that its conclusions will allow the law to inform and guide social and political action to address the ongoing climate crisis.

The #ICJ advisory opinion covers a lot: customary status of climate change-related obligations, what due diligence means for adaptation/mitigation measures, the impact of sea-level rise on statehood, what types of fossil fuel-related activities might constitute an internationally wrongful act. 1/6

#ICJ says fossil fuel production and consumption, granting of fossil fuel exploration licenses, or provision of fossil fuel subsidies may constitute an internationally wrongful act. This is getting into the zone of the ICJ going beyond what states will find credible or politically acceptable. Risky.

This is important guidance from the #ICJ about what due diligence requires in the context of the duty to cooperate on climate change adaptation/mitigation. Why is this important? Because it provides a potential blueprint for climate litigation in domestic courts (see Juliette's next few posts, too).
