Questione giuridica chiave
Whether the appeal against the cantonal judgment ordering a retrospective building permit application was admissible under Art. 93 LTF.
Decisione estratta
The challenged ruling was an incidental decision that did not cause irreparable harm and did not justify immediate federal review.
Motivazione estratta
The order merely required opening a permit procedure to clarify the legality of the commercial use; any objections could be raised later in the building-permit proceedings and, if needed, in a subsequent federal appeal.
