Key legal question
Whether Helvetia Nostra had standing to challenge the building permit under Art. 75b BV and the NHG
Extracted holding
Yes. Recognized environmental and heritage organizations may challenge permits for violations of Art. 75b BV and its transitional/implementing rules.
Extracted reasoning
Second-home caps serve a federal environmental and landscape-protection task; NHG-recognized organizations may appeal against infringements of this federal duty.
