Questione giuridica chiave
Whether the cantonal decision upholding the restoration order was based on a clearly incorrect factual finding affecting proportionality.
Decisione estratta
Yes. The cantonal court wrongly assumed the ridge height exceeded the permitted height by about 85 cm, although the record did not support that finding.
Motivazione estratta
The court held that a change in knee-wall height does not necessarily alter roof pitch. The existing documents did not show any change in the approved roof slope, and the municipality had effectively approved a ridge height of 5 m. Because the cantonal court gave decisive weight to the erroneous ridge-height assumption, its proportionality assessment was unsustainable.
