Kernrechtsfrage
Whether the appeal against the partial judgment was admissible
Extrahierter Entscheid
The appeal was admissible because the lower court decided only a separable preliminary question that could have been brought in an independent action and that was prejudicial to the remaining claims.
Extrahierte Begründung
The subjection question had broader significance and could be raised separately in a declaratory action; therefore the partial judgment was appealable.
