The demand for a judicial review comes from Sudan's army, which is the second party in the civil war. Sudan's military claims that the United Arab Emirates is violating the UN's genocide convention by contributing both weapons and money to RSF.
The ICJ court says it lacks the mandate to take up the case. The reason is that the United Arab Emirates, which signed the genocide convention in 2005, has a clause in its signing that makes it impossible for the ICJ to take up the case.
The court in The Hague in the Netherlands simultaneously established that the civil war between Sudan's army and the paramilitary RSF "is an ongoing humanitarian tragedy that forms the background to the current dispute".
"The violent conflict has a devastating impact with untold losses of life and great suffering, primarily in western Darfur," the court writes in a comment.
The United Arab Emirates welcomed the decision from the ICJ not to take up the allegations, which it claimed were "completely baseless".
Human rights organizations and UN agencies warn that the conflict in Sudan has developed into one of the worst hunger crises and internal refugee disasters in the world at present.
