Kernrechtsfrage
Whether the appeal against the cantonal procedural order was admissible under Art. 93 BGG.
Extrahierter Entscheid
The conditions for immediate review of an interim decision were not met; the appeal was inadmissible.
Extrahierte Begründung
No irreparable legal disadvantage was shown, because the appellant could still challenge a later final decision and would not be forced into litigation without procedural choice. Nor would immediate admission avoid significant time or cost in a voluminous evidentiary procedure, since only the second-home use remained disputed.
