Key legal question
Whether the appeal against the cantonal interlocutory order was admissible under Art. 93 BGG.
Extracted holding
The appeal was inadmissible because no irreparable harm was shown and immediate acceptance could not lead to a final decision or save extensive evidence.
Extracted reasoning
The contested order was a procedural interlocutory measure. Neither ground for independent appeal under Art. 93 Abs. 1 lit. a or b BGG was invoked or apparent, and the parties could challenge the final decision later under Art. 93 Abs. 3 BGG.
