ashington’s top court declined to review an appeal that challenged a decision supporting the National Association of REALTORS® (NAR). The association had already won the case twice in lower courts. In March 2021, Real Estate Exchange, Inc. (REX) sued NAR and Zillow, claiming that NAR’s optional “no‑commingling” rule—requiring non‑MLS listings to appear separately—violated federal antitrust law. The rule, which MLSs could adopt, was rescinded in June. Earlier rulings by the Ninth Circuit and the Western District of Washington favored NAR, and the Supreme Court’s refusal to take the appeal ends the dispute. NAR’s spokesperson reiterated that the rule was never an antitrust violation, citing the district and appellate courts’ affirmations. The association highlighted the role of local MLSs in ensuring transparent, competitive housing markets and pledged to protect the benefits they deliver to agents, buyers, and the industry, even though the rule is no longer in force. Separately, NAR’s executive committee voted to repeal the policy in June, citing declining usage and feedback from the MLS community, as explained by Associate General Counsel Charlie Lee.
