Key legal question
Whether Helvetia Nostra had standing to appeal the building permit.
Extracted holding
Standing was recognized because the project concerned a federal task under nature and landscape protection rules.
Extracted reasoning
The court relied on its leading judgments of 22 May 2013: associations entitled under Art. 12 LPN may appeal where the dispute concerns a federal task; a permit for a secondary residence falls within Art. 75b Cst. and thus within federal law.
