Kernrechtsfrage
Whether the Republic could invoke state immunity to oust Swiss jurisdiction
Extrahierter Entscheid
The immunity objection was time-barred because the State participated in the proceedings without raising it and thereby waived it by conduct.
Extrahierte Begründung
State immunity must be invoked immediately when the State is sued; after filing merits submissions and participating in related interim proceedings, silence amounts to tacit waiver.
