Questione giuridica chiave
Whether the 1980 shed permit allowed commercial use and whether the permit was null
Decisione estratta
The permit expressly limited use to agriculture; no commercial use was authorized, and the permit was not void despite procedural defects.
Motivazione estratta
The wording of the permit was clear, the later file notes did not replace a formal approval, and the irregular cantonal approval mechanism did not amount to a particularly grave, obvious defect justifying nullity.
