Jason C. Vigna


[email protected]



Jason is an accomplished litigator who represents defendants in shareholder and other high-stakes disputes. He has prominently defended issuers, officers, directors, underwriters and others in shareholder class and derivative litigation in trial and appellate courts throughout the United States and before the Securities and Exchange Commission. Jason also represents clients in complex commercial litigation and corporate governance disputes. His clients include companies and individuals from a variety of industries, especially in the life sciences, financial services and technology sectors.

Jason has represented clients in some of the largest securities fraud cases in history – successfully defending more than 60 class, derivative, bankruptcy and individual actions arising from the unravelling of Bernie Madoff’s Ponzi scheme and playing a significant role in several other high-profile securities cases, including Worldcom, Refco, AIG and the “IPO laddering” cases.

Attuned to his clients’ needs and goals, Jason is an innovative, effective litigator who leverages his business insight and knowledge of his clients’ industries to develop and deploy strategies that frequently lead to early case dismissals. In a survey conducted by the Legal 500 United States, Jason was commended as an attorney with “strong intuition and a strategic mindset.”

Prior to joining Mintz, Jason was a partner at another large law firm, where he helped clients resolve disputes involving federal and state shareholder- and fraud-related statutes, including the Securities Exchange Act of 1934, the Securities Act of 1933, the Racketeering Influenced and Corrupt Organizations (RICO) Act and the Delaware General Corporation Law. He also represented clients in general complex commercial litigation.

In addition to US clients, Jason has successfully represented numerous foreign companies, including several from Israel and others from Canada, China, Germany, Kazakhstan, Ireland, Italy and Singapore.

Before entering private practice, Jason clerked for the Honorable J.P. Stadtmueller of the US District Court for the Eastern District of Wisconsin.
