Jason Vigna represents clients in complex securities, commercial and corporate governance matters in trial and appellate courts throughout the country and before the Securities and Exchange Commission (SEC) and Financial Industry Regulatory Authority (FINRA). He has helped asset management firms, banks and other sophisticated companies, as well as their directors and officers, successfully resolve disputes involving a wide variety of federal and state statutes, including the Securities Exchange Act of 1934, the Securities Act of 1933, the Racketeering Influenced and Corrupt Organizations (RICO) Act, the Delaware General Corporation Law and the New York Business Corporation Law. He also has litigated a broad range of related common law claims, including claims for alleged breach of fiduciary duty, breach of contract, fraud and negligence.

Jason recently defended an asset management company and its employees in more than 60 high-profile class, derivative, bankruptcy and individual actions arising out of hedge fund investments made with Bernard Madoff. In addition, he represented a global banking and financial services company and its affiliates in their defense of claims brought by the trustee of the Bernard L. Madoff Investment Securities LLC estate. In that capacity, Jason helped obtain the withdrawal from bankruptcy court and pre-trial dismissal of all RICO, common law and clawback claims asserted against his clients in parallel multi-billion dollar lawsuits. This effort was named among the top matters in the Litigation and Dispute Resolution category in the Financial Times' 2013 "US Innovative Lawyers" report. He also coordinated the defense of 46 defendants represented by 20 law firms in securing the dismissal of three private class action lawsuits arising out of the same alleged acts.

Before practicing law, Jason clerked for the Honorable J.P. Stadtmueller of the US District Court for the Eastern District of Wisconsin.
