Question juridique clé
Whether abusive-rent protection rules apply to leases between a housing cooperative and its member-tenants.
Solution extraite
Yes. The rules on contesting abusive rents apply to housing cooperative leases unless the statutory exception of public subsidy and administrative rent control is met.
Motifs extraits
The cooperative and the tenant are bound by two distinct legal relationships: a corporate relationship and a lease. The tenant's cooperative status does not remove the protection against abusive rent; internal cooperative mechanisms are not equivalent to tenancy-law safeguards, and article 253b(3) CO implies by contrast that cooperative housing not under public rent control remains subject to articles 269 ff. CO.
