Question juridique clé
Whether Swiss courts had jurisdiction under Art. 88 IPRG over the heir's information claims concerning the estate
Solution extraite
Yes. The inheritance-information claims were sufficiently linked to the estate so that Art. 88 IPRG applied even if Swiss assets were not proven to exist at the time of filing.
Motifs extraits
The Court held that heirs' access to information is closely connected to the acquisition and existence of the estate. Because the requested disclosures concern the estate in Switzerland, jurisdiction cannot depend on proving Swiss assets at the time of suit.
