Kernrechtsfrage
Whether Helvetia Nostra had standing to challenge the permit under Art. 12 NHG and Art. 75b BV.
Extrahierter Entscheid
Yes. Nature and heritage organizations entitled to appeal under Art. 12 NHG may challenge building permits for alleged violations of Art. 75b BV and its transitional and implementing rules.
Extrahierte Begründung
Plafoning second-home construction serves a federal task protecting nature and the landscape; therefore the organization had complaint and objection standing.
