The US Supreme Court denied NAR’s appeal to review a lower court’s ruling that a lawsuit the private listing firm The NLS (National Listing Service) filed against NAR and three large MLSs could proceed. The NLS alleges that NAR’s Clear Cooperation Policy, which requires brokerages to input listings into MLSs within one day of marketing publicly, and its application by MLSs violates antitrust provisions as the policy limits competition from listing databases not affiliated with NAR. In addition to this litigation, NAR faces significant legal challenges with the federal government and class-action suits challenging the industry’s traditional brokerage compensation model.
