Mark Horning represents insurance industry clients in litigation matters, principally those involving coverage, antitrust, unfair trade practice, fraud, Racketeer Influenced and Corrupt Organizations Act (RICO), and regulatory cases. Mr. Horning has represented clients in significant coverage disputes with policyholders, government enforcement proceedings, parens patriae actions by state attorneys general, and private class actions brought in both federal and state court. He has substantial familiarity with class certification issues under both federal and state rules. Additionally, he regularly addresses exemptions and immunities from federal and state laws available to insurers, including the McCarran-Ferguson Act, the state action doctrine, the Noerr-Pennington doctrine, the filed rate doctrine and the doctrines of exclusive and primary jurisdiction. He also has extensive knowledge of state unfair and deceptive practices acts, or “FTC acts,” often relied upon in private class actions.

In recent years, he has represented insurers in commercial property insurance coverage disputes and litigation with the government relating to surety bonds. He has also represented insurers in antitrust and RICO cases brought by state attorneys general and private class action plaintiffs alleging any of the following: agreements to restrict environmental coverages in commercial liability policies; agreements to raise rates for windstorm coverages in homeowners’ policies; agreements to withdraw from workers’ compensation insurance markets; and agreements to fix the price for services provided in so-called “residual markets.”  With respect to litigation involving RICO, unfair trade practice, and fraud claims, he has represented insurer clients in cases alleging failure to disclose use of unapproved rates, failure to disclose use of so-called “aftermarket crash parts” in automobile repairs, and alleged bad faith refusal to pay for diminution in value of motor vehicles covered by automobile insurance policies.
