Question juridique clé
Whether the Swiss courts had international jurisdiction over the wife's information request against the bank.
Solution extraite
Yes. The request was not an ancillary measure under art. 10 LDIP, but a separate action against a bank; jurisdiction lay at the bank's seat under art. 2 LDIP.
Motifs extraits
Art. 10 LDIP may support exceptional interim measures in foreign divorce proceedings between the same spouses, but that reasoning does not apply to a direct claim against a third-party bank. For such a request, the forum is the defendant's seat.
