Key legal question
Whether Helvetia Nostra had standing to object and appeal under nature and heritage law
Extracted holding
Yes. Organizations entitled to appeal under the Nature and Heritage Protection Act may challenge building permits alleging violations of the second-home limits.
Extracted reasoning
The second-home cap serves a federal nature-protection task, and organizations recognized under Art. 12 NHG may invoke Art. 75b BV and its transitional/implementing provisions.
