Key legal question
Whether the lease terminations of 30 May 2001 were valid under Art. 257f(3) CO
Extracted holding
Yes. The tenant had persistently breached her duty of diligence by refusing, despite written warnings, to remove the store and permit necessary repairs; keeping the leases in force had become unbearable for the landlord.
Extracted reasoning
The works were necessary repairs/maintenance under Art. 257h CO, not mere improvements. The tenant had been expressly warned, still obstructed the works, and even challenged them administratively. Given the concrete circumstances, the cantonal court did not abuse its discretion in finding unbearable continuation of the tenancy.
