Complex commercial litigation and arbitration, with an emphasis on reinsurance, insurance, financial services, healthcare, and antitrust disputes, as well as franchise and distribution counseling


Jason represents companies in a variety of complex commercial litigations and arbitrations, with an emphasis on reinsurance, insurance, healthcare and antitrust disputes, as well as franchise and distribution counseling. Regardless of the substance of the matter, Jason seeks to fully understand his client’s objective for the engagement and maintain frequent communication throughout the pendency of the matter to assure that objective is obtained. As a former economic analyst – both with the Antitrust Division of the U.S. Department of Justice and with Capitol Economics in Washington, D.C. – Jason also brings to his practice the perspective of an economist and a regulator.

Jason has particular experience advising and representing corporate clients in litigation to remedy the economic damages they have incurred as a result of antitrust conspiracies in the market for key inputs into their own business operations. Along those lines, he is currently following developments in In Re: Generic Pharmaceuticals Pricing Antitrust Litigation, MDL 2724, and has recently spoken with NPR and a nationally-syndicated morning news television program on the widening generic drug price fixing investigation and related litigation.

Jason’s experience includes successfully defending clients against allegations of RICO, fraud, conspiracy and breach of contract. He has first-chaired and second-chaired a number of significant reinsurance arbitrations, representing both cedents and reinsurers. Among those arbitrations, Jason has dealt with multiple disputes involving automobile dealer/producer-owned reinsurance companies and cedents over the termination of their reinsurance agreements, having served as counsel as well as umpire and party-appointed arbitrator on ADR panels faced with such issues. Jason also regularly advises clients on changes to their existing product distribution networks.

Jason began his law career with Jones Day in Washington, D.C., where he concentrated on antitrust counseling and litigation, including the successful defense of both a prominent price-fixing investigation and a notable merger challenge brought by an industry competitor under Section 7 of the Clayton Act.
