Key legal question
Whether the appeal against the cantonal interlocutory decision was admissible under Art. 93 LTF
Extracted holding
The decision was interlocutory, and the appellant did not show that an immediate review would avoid a long and costly evidentiary proceeding.
Extracted reasoning
The alleged irreparable harm failed because the interlocutory ruling can be challenged together with the final judgment. The prospect of further evidence on damage, including possible expert evidence, did not clearly amount to a particularly long and costly procedure.
