Kernrechtsfrage
Whether the lease termination for economic reasons was valid
Extrahierter Entscheid
The notice was abusive because the landlord did not prove that a lawful rent increase would have been possible under the absolute method.
Extrahierte Begründung
A termination to obtain a higher rent is permissible only if the landlord may lawfully demand a higher rent. The comparative-rent evidence did not establish this, so the notice served an impermissible purpose.
