Kernrechtsfrage
Whether the cantonal courts had territorial jurisdiction over both defendants under former Art. 7(1) GestG
Extrahierter Entscheid
Yes. The claims against both defendants were sufficiently connected because they relied on the same core facts and legal grounds, so one forum could hear both.
Extrahierte Begründung
The brokerage claims depended on the same conduct of the first defendant and the same contractual context; a joint hearing avoided potentially contradictory decisions.
