Cantonal Authority Zoning Decision Upheld in Building Permit Revocation

A petitioner sought judicial review of a decision by a cantonal authority that revoked the building permit for an annex to an existing structure, arguing that the authority had misapplied zoning regulations by classifying the planned annex as a new main building requiring adherence to stricter setback rules, rather than a permissible accessory structure. The court affirmed the authority's decision, reasoning that the proposed annex, due to its size and functional relationship to the main building, constituted an extension that significantly altered the site's building volume and, therefore, could not benefit from the more lenient rules applicable to minor accessory structures, thus justifying the revocation based on non-compliance with established distance requirements from neighboring properties.
