Question juridique clé
Whether Helvetia Nostra had standing to appeal the building permit in a matter governed by Art. 75b Cst.
Solution extraite
Standing had to be recognized, because the permit concerns a task of the Confederation and Helvetia Nostra is an authorized environmental and landscape-protection organization.
Motifs extraits
The Court relied on its 22 May 2013 case law: Art. 75b Cst. is directly applicable and serves nature and landscape protection; permits for second residences therefore fall within a federal task under Arts. 78 Cst. and 2 LPN.
