Weil die Botschaft die Bauvorschriften durch das unterlassene Abstützen verletzte, gilt die Ausnahme für unerlaubte Handlungen vom FSIA, und das Bundesgericht darf seine Gerichtsbarkeit über die Botschaft ausüben, entschied das Bundesberufungsgericht des zweiten Bezirks der USA im Fall USAA Casualty Insurance Co. v. Permanent Mission of the Republic of Namibia am 25. Mai 2012 mit diesen Folgerungen:
(1) The Mission owed a nondelegable duty to [the neighbor] pursuant to Section 3309.8 of the New York City Building Code, to ensure the structural integrity of the common party wall during the course of construction at the future site of the chancery.
(2) Because the Mission allegedly breached its nondelegable duty, it may not invoke the shield of sovereign immunity in the Foreign Sovereign Immunities Act to avoid a lawsuit seeking to hold it liable for damage to Adelman’s property.
(3) The Mission may not avail itself of the discretionary function exception to the tortious activity exception to the FSIA―the “exception to the exception”―in order to avoid tort liability, because its failure to ensure the structural integrity of the party wall was not discretionary.
