Kernrechtsfrage
Whether the ordinary lease termination for repeated late rent payments was valid under good faith rules.
Extrahierter Entscheid
The termination was valid because repeated late payment of rent is a legitimate reason for an ordinary termination and the notice complied with formal requirements.
Extrahierte Begründung
The contract was of indefinite duration; the landlord respected the contractual and legal notice period. The termination was ordinary, not based on default under Art. 257d CO. The landlord had a legitimate interest in punctual payment, and the tenants repeatedly paid late.
