Kernrechtsfrage
Whether the landward part of the wooden deck could be justified by legitimate expectations from municipal statements
Extrahierter Entscheid
No protected reliance existed because the municipality lacked clear authority to approve the structure, and the builders—especially the lawyer and architect involved—had to know this.
Extrahierte Begründung
A trust-based claim under Art. 9 BV fails if the reliance is not objectively justified or if overriding public interests prevail. The prior municipal letter was only a 'statement' and could not replace the formal building permit system; the applicants also knew from earlier planning history that exceptions in the shore-protection zone required cantonal approval.
