Key legal question
Whether the cantonal prejudicial judgment was immediately appealable to the Federal Court
Extracted holding
The cantonal judgment was an incidental decision under Art. 93 LTF and none of the conditions for immediate appeal was met.
Extracted reasoning
It did not end the main dispute or decide a separable part of it; the appellant did not show irreparable legal harm, and immediate review would not lead to a final decision avoiding extensive evidence proceedings.
