Kernrechtsfrage
Whether the federal civil appeal was admissible against the cantonal decision on liability in principle.
Extrahierter Entscheid
The cantonal ruling was an interlocutory decision, not a final or partial decision. The appellant failed to show any exception under Art. 93(1) BGG, so the appeal was not admissible.
Extrahierte Begründung
The decision concerned only a preliminary liability question; the merits on quantum still had to be decided by the first instance. No irreparable harm was asserted, and the appellant did not demonstrate that immediate review would avoid extensive evidence proceedings.
