Jason Dubner is a litigator in Holland & Knight's Chicago office, where he focuses his practice on assisting insurers and their managing general agents (MGAs) with the analysis and resolution of representations and warranties insurance (RWI) claims.

Mr. Dubner has experience with various types of RWI claims, including alleged breaches of representations regarding an absence of changes, condition of assets, compliance with laws, and financial statements, as well as those regarding material contracts, customers and suppliers. Prior to joining Holland & Knight, Mr. Dubner was the co-chair of the RWI practice at the Chicago office of a large national law firm.

Mr. Dubner also has handled a variety of complex commercial litigations and arbitrations, with an emphasis on reinsurance, insurance and antitrust disputes. Since 2017, he has been an appointed panelist on the American Arbitration Association (AAA) National Roster of Arbitrators, where he maintains an active AAA arbitration practice adjudicating commercial disputes.

As a former economic analyst with the Antitrust Division of the U.S. Department of Justice (DOJ), Mr. Dubner brings the combined perspectives of an economist and a regulator to his practice. He has more than 20 years of experience advising and representing corporate clients in litigation to remedy the economic damages that they have incurred as a result of antitrust conspiracies in the market for key inputs into their own business operations. Mr. Dubner has also represented organizations defending against class action allegations that their companies have been part of an antitrust conspiracy either to fix prices or reduce output in a variety of industries. His experience also includes successfully defending clients against related allegations of Racketeer Influenced and Corrupt Organizations (RICO) Act violations, fraud, conspiracy and breach of contract. In addition, Mr. Dubner advises clients on changes to their existing product distribution networks. He also has experience counseling clients on antitrust matters before state and federal regulators, including in response to third-party subpoenas and civil investigative demands (CIDs).

Mr. Dubner also has first-chaired and second-chaired a number of significant reinsurance arbitrations, representing cedents and reinsurers. Among those arbitrations, Mr. Dubner 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 Alternative Dispute Resolution (ADR) panels faced with related issues.
