Kernrechtsfrage
Whether the neighbors' letter had to be treated as a formal objection despite its informal wording.
Extrahierter Entscheid
The authority could not dismiss the letter as merely informal; it had to be treated afterward as an objection.
Extrahierte Begründung
Laypersons cannot be held to high formal standards. The authority should have clarified whether the submission was meant as an objection before deciding the building permit.
