Key legal question
Whether the refusal of authorizations to alienate the rented apartments under LDTR was arbitrary or violated property rights.
Extracted holding
The cantonal court's balancing of interests was not arbitrary and did not breach property guarantees; the public interest in preserving the rental housing stock prevailed.
Extracted reasoning
The owners showed only a commercial interest, while the sales would contribute to a progressive fragmentation of a rental building in a housing-short market. LDTR aims to preserve existing housing conditions and locative use, and the small block sales increased the risk of gradual conversion.
