Questione giuridica chiave
Whether Helvetia Nostra had standing to object and appeal against the building permit.
Decisione estratta
Yes. Environmental and landscape-protection organizations entitled under Art. 12 NHG may challenge permits for violations of Art. 75b BV and related provisions.
Motivazione estratta
The second-home cap serves a federal task protecting nature and the landscape; therefore the organization had appeal standing and the municipality/cantonal court erred in denying it.
