Key legal question
Whether Swiss courts had international jurisdiction over the divorce action under Art. 59 IPRG based on the wife's domicile in Switzerland.
Extracted holding
The wife's domicile had not been transferred to Switzerland at the time the action was filed; Zurich courts lacked international jurisdiction.
Extracted reasoning
The decisive circumstances still pointed to the center of life in the Czech Republic: her business, financial interests, social network, and own apartment remained there, while the Zurich registration and other indicators did not show a sufficiently manifest shift of ties to Switzerland.
