Questione giuridica chiave
Whether Swiss courts had jurisdiction over the divorce action and Swiss law applied to the divorce.
Decisione estratta
Swiss jurisdiction was proper because the husband, as plaintiff, was a Swiss citizen; Swiss law governed the divorce because the spouses did not share a common effective nationality.
Motivazione estratta
Under the IPRG, a Swiss plaintiff may sue in Switzerland. For multiple nationality, effective nationality controls. The husband was more closely connected with Switzerland than Germany, so no common German nationality in the IPRG sense existed.
