Six multiple listing services filed a federal lawsuit Wednesday against Compass International Holdings, escalating a national dispute over whether brokerages may publicly market listings while withholding them from the cooperative MLS database.
The plaintiffs are Arizona Regional MLS, Bridge MLS, Canopy MLS, REcolorado, Hive MLS and Doorify MLS. They filed the case October 21 in the U.S. District Court for the Southern District of New York, according to reporting based on the complaint by HousingWire and Inman.
The MLS organizations seek declaratory and injunctive relief. They want a court to find that their cooperation requirements do not violate antitrust law and to restrict Compass from pursuing claims attacking those rules. These are requests for relief, not rulings already granted by a judge.
Competing arguments over listing access
The plaintiffs contend that rules requiring publicly marketed properties to be promptly shared with MLS participants protect the completeness and usefulness of listing databases. They argue that allowing brokers to use the shared database while withholding their own publicly marketed inventory would undermine cooperation and market transparency.
Compass disputes that premise. In a statement reported by HousingWire, the brokerage said homeowners should be able to publicly market listings without agents facing substantial MLS fines. Compass maintains that sellers, rather than MLS organizations, should control lawful marketing choices.
The filing follows California Regional MLS’s earlier federal action and Compass’s subsequent antitrust lawsuit against CRMLS. The six-MLS case is separate litigation.
The dispute could influence national listing distribution, private-listing strategies and how brokerages compete for sellers. No court has resolved the competing antitrust arguments in this newly filed action.
The complete federal docket and exact filing timestamp were not independently reviewed at publication.
