Question juridique clé
Whether the municipal authorities lacked competence to order restoration because the construction was allegedly outside the building zone and required cantonal authorization.
Solution extraite
The restoration order was not invalid for lack of municipal competence; Article 25(2) LAT does not exclude a municipal restoration power.
Motifs extraits
Even if the mayens zone were not a building zone, federal law does not expressly bar cantonal or municipal competence to order restoration. The office's reliance on competence rules for building permits could not simply be transferred to restoration orders.
