On February 5, 2024, Plaintiffs brought suit on behalf of the class of Commercial Health Plan Members against Aurora Health Care and Advocate Aurora Health in the United States District Court for the Eastern District of Wisconsin claiming restraint of trade, unlawful monopolization, and unfair methods of competition in violation of the Sherman Act.  The suit claims Advocate Aurora used its market dominance to restrain trade, resulting in unreasonably high prices for Wisconsin commercial health plans and their members.
