Question juridique clé
Whether Helvetia Nostra had standing to challenge the building permit.
Solution extraite
Standing had to be recognized because the association is authorized to appeal in nature and landscape protection matters and the permit concerns a federal task within the meaning of the Constitution and the Nature and Heritage Protection Act.
Motifs extraits
The court relied on its leading judgments of 22 May 2013 and held that Art. 75b Cst. aims at nature and landscape protection; permits for secondary residences are therefore linked to a federal task, making the association's appeal admissible.
