Kernrechtsfrage
Whether the appellants were entitled to challenge the building permit despite not filing a formal objection during the notice period.
Extrahierter Entscheid
No. Under cantonal law, objection participation was a prerequisite for standing, and the appellants had not filed a valid objection.
Extrahierte Begründung
The relevant cantonal provisions required a formal, timely objection. No exception applied, and the appellants deliberately refrained from filing one.
