Kernrechtsfrage
Whether the lease terminations for planned renovation were abusive and therefore voidable under the good-faith rule.
Extrahierter Entscheid
The notices were abusive because the renovation project had not reached maturity and lacked tangible reality; an effective, protected interest was not shown.
Extrahierte Begründung
Art. 260 CO does not govern the validity of a notice given in view of future renovations. Under Art. 271 CO, a landlord may terminate for intended major works only if the project is concrete and the interest is real and protectable. That was not established here.
