Key legal question
Whether Helvetia Nostra had standing to appeal
Extracted holding
Helvetia Nostra was entitled to appeal as an association authorized under nature and landscape protection law when the permit concerns a federal task.
Extracted reasoning
The Court relied on its 22 May 2013 leading case: secondary-residence permits implement a federal task under Arts. 78 Cst. and 2 LPN, so standing exists under Art. 12 LPN.
