Karin A. DeMasi is Managing Partner of Cravath’s Litigation Department.

Commended as an “excellent litigator” with “strong court presence,” she focuses her practice on complex litigation, including class actions, in the areas of antitrust, securities, derivative, ERISA and general commercial disputes. (The Legal 500 US)

Although many of her cases have been successfully resolved for her clients on pre trial motions, Ms. DeMasi’s experience also includes numerous jury and bench trials, as well as domestic and international arbitrations. She has represented a wide range of companies, including boards of directors and individuals, across industries.

• Representing the Blue Cross Blue Shield Association (“BCBSA”) and more than a dozen member plans in consolidated multidistrict antitrust class action litigation—one of the largest class actions in the country—brought by putative classes of healthcare providers and health insurance subscribers alleging that the Association and its members have used the Association’s agreements to fix prices and limit competition. She also represents BCBSA and various member plans in related opt out litigation across the country brought by large self funded subscribers and providers.
• Represented First Solar and certain of its senior executives in winning back to back dismissals to defeat putative class action securities litigation filed in Arizona federal court alleging defendants made false and misleading statements regarding the company’s “Series 6” solar module and its project development business. Ms. DeMasi also represented First Solar in related shareholder derivative litigation, which was voluntarily dismissed.
