Questão jurídica principal
Whether the rules on contesting abusive rents under Arts. 269 ss CO apply to leases concluded by a housing cooperative with its members.
Decisão extraída
Yes. A housing cooperative does not fall outside the protective rent-control regime merely because the tenant is also a member; cooperative and lease relations remain distinct, and the statutory exception of Art. 253b para. 3 CO does not cover such cases.
Fundamentação extraída
The member's corporate rights do not provide equivalent protection; a one-member-one-vote structure does not meaningfully protect against excessive rent, and recourse to company-law remedies would deprive tenants of the procedural safeguards of tenancy law. Any inequality between members arises from individual procedural action, not from a cooperative decision. The statutory exception for publicly subsidized and officially controlled housing applies only cumulatively and does not imply an exclusion for cooperatives.
