Key legal question
Whether Helvetia Nostra had standing to challenge the building permit
Extracted holding
Yes. Organizations entitled under Art. 12(1)(b) NHG may appeal permits alleging violation of Art. 75b BV and its transitional/executing rules.
Extracted reasoning
The second-home cap under Art. 75b BV serves nature and landscape protection and is a federal task; thus NHG-recognized conservation organizations may contest such permits.
