Habe gestern Abend kurz im Interview mit dem BR die politische Debatte um die Ukraine-Unterstützung & #Taurus rechtlich eingeordnet. Kann man in der ARD-Mediathek nachhören: www.ardmediathek.de/video/br24/i....

Nicaragua has sued Germany at the ICJ for supporting Israel. But which of the claims can the Court hear the case without Israel being a party? Robert Stendel and I have written up some thoughts on whether Israel is an indispensable third party @verfassungsblog.de. verfassungsblog.de/conspicuousl...

Nicaragua accuses Germany of violating the Genocide Convention and international humanitarian law by aiding Israel in the ongoing war. Alexander Wentker and Robert Stendel discuss whether Nicaragua’s requests for provisional measures v. Germany fall under ICJ’s jurisdiction.
