Key legal question
Whether the Federal Supreme Court could hear an immediate appeal against the cantonal incidental decision under Art. 93 LTF
Extracted holding
The appeal was not admissible because the appellant did not establish that immediate review would avoid a long and costly evidentiary procedure.
Extracted reasoning
Although a different ruling on prescription would end the case, the appellant failed to specify remaining factual disputes or any evidence-taking that would make the proceedings lengthy and expensive; a mere legal complexity or protracted litigation is insufficient.
