Update 7 December 2021 the judgment was confirmed upon appeal.
The judgment (in first instance; expect appeal) dismissing jurisdiction in Ismail Ziada v Benjamin Gantz is out in Dutch here and in English here. Gilles Cuniberti has reviewed the immunity issues here. I shall focus on the consideration of forum necessitatis, and can so do very briefly for the court does, too.
In essence the judgment on this point means that civil procedure rules on forum necessitatis do not set aside sovereign immunity based on public international law, and that the ECtHR judgment in Naït-Liman does not alter that finding. In that case, the ECtHR nudged States to consider a forum necessitatis rule:
‘“Nonetheless, given the dynamic nature of this area, the Court does not rule out the possibility of developments in the future. Accordingly, and although it concludes that there has been no violation of Article 6 § 1 in the present case, the Court invites the States Parties to the Convention to take account in their legal orders of any developments facilitating effective implementation of the right to compensation for acts of torture, while assessing carefully any claim of this nature so as to identify, where appropriate, the elements which would oblige their courts to assume jurisdiction to examine it.”
In Ismail Ziada v Benjamin Gantz the Court simply remarked that ECtHR authority on the issue all concerns immunity of international organisations not, as here, State sovereign immunity, in which consequently (in the court’s view) forum necessitatis does not have a role to play.
