Question juridique clé
Whether the tenants validly withdrew from the lease under the permit-refusal clause
Solution extraite
Yes. The clause covered the project-specific refusal risk, the relevant approval refusals occurred, and the withdrawal was timely.
Motifs extraits
The landlords knew the tenants sought to implement a rehabilitation-center concept requiring approvals beyond ordinary individual licensing. By later accepting a clause referring to the cantonal insurers as well, they had to understand that the tenants were safeguarding against failure of the specific operating concept, not only against a minimal routine risk.
