Kernrechtsfrage
Whether the cantonal judgment on building-permit duty for the installation was immediately appealable to the Federal Supreme Court.
Extrahierter Entscheid
Yes. The order was a separately appealable interim decision; admitting the appeal could end the case immediately and avoid a lengthy permit procedure.
Extrahierte Begründung
Under Art. 93(1)(b) BGG, the appeal was admissible because a successful challenge would definitively remove the need for a building-permit proceeding and save time and costs.
