Key legal question
Whether Helvetia Nostra had standing to object and appeal against the building permit under the second-home restrictions.
Extracted holding
Yes. Conservation organizations entitled to appeal under the NHG may challenge building permits alleging violations of Art. 75b BV and its transitional/implementing rules.
Extracted reasoning
The second-home cap serves protection of nature and the landscape and is a federal task; thus NGOs with appeal standing under Art. 12(1)(b) NHG may attack permits for breach of Art. 75b BV and related provisions.
