Ninth Circuit Judge Signals Potential Revival of Antitrust Claims Against CoStar Group

In a recent hearing, a Ninth Circuit judge indicated a willingness to revive counterclaims in a case against CoStar Group Inc., challenging its alleged monopolization of the commercial real estate information markets. The judge expressed concerns that the lower court’s decision, which had favored CoStar, resembled a summary judgment rather than a proper dismissal. This interpretation suggests the lower court may have improperly sided with CoStar by drawing inferences to their advantage. The outcome of a potential retrial could significantly impact legal standards concerning monopolistic practices within the real estate sector.
