Kernrechtsfrage
Whether the municipality had standing to appeal the building permit judgment.
Extrahierter Entscheid
The municipality had standing as an adjacent owner under Art. 89 para. 1 LTF, but not under Art. 89 para. 2 LTF or Art. 34 para. 2 LAT.
Extrahierte Begründung
It was directly affected as a neighboring proprietor and invoked building-law provisions affecting its legal and factual position; a mere interest in correct law application was insufficient for public-authority standing.
