Question juridique clé
Whether the department could order correction of the lease to remove the post-control rent escalation clause
Solution extraite
No. The department could ensure compliance with the administrative rent-control condition during the three-year control period, but it had no competence to regulate the rent after that period or to annul a contractual escalation clause.
Motifs extraits
Cantonal rent-control measures may require a lease to reflect the administratively fixed rent during the control period, but post-control rent matters belong to federal private tenancy law. For the period after control, the tenants had to challenge the lease before the civil courts under Art. 270 CO.
