Questione giuridica chiave
Whether the appeal against the cantonal incidental liability decision was admissible under Art. 93 LTF
Decisione estratta
The appeal was inadmissible because the appellant failed to show that an immediate Federal Supreme Court decision would avoid defatigating or costly evidence proceedings.
Motivazione estratta
The decision was not final. No irreparable harm was alleged. For Art. 93(1)(b) LTF, the appellant had to explain which evidence remained to be taken and why it would be burdensome; merely asserting that the case could end immediately was insufficient.
