Kernrechtsfrage
Whether the third-party claim was sufficiently connected to the main claim under Art. 81-82 ZPO
Extrahierter Entscheid
The court left the question open, because the claim was in any event inadmissible for lack of quantified relief.
Extrahierte Begründung
A third-party claim may only pursue claims dependent on the main claim, but the court did not need to decide whether this connection was adequately pleaded.
