Kernrechtsfrage
Whether the appellants had standing to challenge the merits of the building permit
Extrahierter Entscheid
They lacked standing on the merits because they pursued only public interests, but could still raise procedural violations as a denial of justice.
Extrahierte Begründung
Under Art. 88 OG, a state-law complaint requires a legally protected interest; public-interest associations cannot use it to contest the substantive assessment. Their participation in the cantonal proceedings still allows complaints about procedural rights.
