Key legal question
Whether Helvetia Nostra had standing to appeal against the building permit.
Extracted holding
Standing had to be recognized in light of the Federal Supreme Court's principle case law on art. 12 LPN and art. 75b Cst.
Extracted reasoning
The project concerned a task of the Confederation under art. 78 Cst. and 2 LPN because the permit involved a residence potentially subject to the federal secondary-residence cap.
