Should standard lease terms and tenant protections be legally binding?

AI-generated summary, admin reviewed: This constitutional amendment allowed the government to make framework lease agreements negotiated between landlord and tenant organisations legally binding. Such agreements could cover minimum tenancy periods, termination rules and joint dispute-resolution bodies. The government could also protect tenants from abusive rents in areas suffering from housing or commercial-property shortages. The proposal did not establish general rent-price controls. Supporters argued that these powers were needed to protect tenants during housing shortages. Opponents feared excessive government intervention in the rental market. Swiss voters approved the amendment.
