Kernrechtsfrage
Whether the permit for a secondary residence issued on 2012-12-18 was compatible with Art. 75b Cst.
Extrahierter Entscheid
The permit violated Art. 75b Cst.; it had to be annulled and the construction request definitively rejected.
Extrahierte Begründung
The permit was issued after the constitutional provision entered into force; the commune already exceeded the 20% secondary-residence threshold, and the project was for a secondary residence. Under the Court's case law, such permits issued before 2013-01-01 are voidable, not null, but remain unlawful.
