Questione giuridica chiave
Whether the public-law complaint against the cantonal judgment was admissible under Art. 93 BGG.
Decisione estratta
The challenged judgment was an interlocutory decision; no irreparable harm or exceptional ground for immediate review was shown, so the complaint was inadmissible.
Motivazione estratta
The building permit proceedings were not finally concluded because the drainage/sewerage project had been severed and left to a later authorization procedure. Without a practical final effect and without proof of irreparable harm or major evidentiary economy, Art. 93 BGG was not satisfied.
