Kernrechtsfrage
Whether the appeal against the cantonal interlocutory decision was admissible under Art. 93 LTF.
Extrahierter Entscheid
The appeal was inadmissible because the appellant failed to show that the decision could cause irreparable harm or that immediate review would avoid long and costly evidence proceedings.
Extrahierte Begründung
Although the disputed issues could in principle end the case immediately, the appellant did not meet the strict burden of showing a lengthy and costly evidentiary procedure, especially as he did not specify the foreign witnesses, the precise facts to be proved, or that they would refuse to appear voluntarily.
