Questione giuridica chiave
Whether the termination for economic reasons was valid under the rules on abusive termination and neighborhood rents.
Decisione estratta
The notice could not be upheld on the basis of the cantonal court's overly narrow definition of the relevant neighborhood; the case had to be reconsidered.
Motivazione estratta
A lease termination aimed at raising rent is invalid if the landlord cannot lawfully demand a higher rent under the absolute method. The cantonal court wrongly restricted 'neighborhood' too narrowly and excluded potentially comparable objects without first defining the neighborhood independently of the comparison criteria.
