Kernrechtsfrage
Whether the appellant had standing and whether the complaint was timely
Extrahierter Entscheid
The complaint in public law matters was admissible in principle because the appellant owned a neighboring apartment and filed within the deadline.
Extrahierte Begründung
As an adjacent owner, he was directly affected and thus entitled to appeal under Art. 89(1) BGG; the filing was within the statutory time limit.
