Kernrechtsfrage
Whether the federal appeal was admissible against the cantonal partial decision on jurisdiction.
Extrahierter Entscheid
The appeal was admissible because the decision finally disposed of the claims against one defendant and an immediate federal ruling could avoid significant additional evidentiary costs.
Extrahierte Begründung
The court treated the decision as a partial judgment in a subjectively joindered case and, by analogy to Art. 50 OG, allowed separate appeal where the scope of evidence would materially depend on whether all defendants remained in the case.
