Question juridique clé
Whether the ordinary lease termination for repeated late rent payments was valid under good faith rules.
Solution extraite
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.
Motifs extraits
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.
