Kernrechtsfrage
Whether Geneva courts had jurisdiction over the heirs' action for partition of the estate.
Extrahierter Entscheid
Yes. The appellant's prior proceedings in Geneva amounted to an implied forum prorogation and, in any event, her jurisdictional objection was an abuse of rights.
Extrahierte Begründung
A party who voluntarily seizes the Geneva courts on the same succession dispute cannot later contest that forum in a parallel action with identical subject matter; this is contrary to venire contra factum proprium.
