Kernrechtsfrage
Whether Swiss courts had direct jurisdiction to decide parental care and visitation in the divorce case
Extrahierter Entscheid
The Swiss divorce court lacked direct jurisdiction because the children had their habitual residence in France; child-related matters belong before the authorities at the child's habitual residence.
Extrahierte Begründung
International conventions governing protection of minors and parental responsibility allocate jurisdiction to the child's habitual residence. The unity of the divorce judgment yields to those treaty rules.
