About Jason C. Vigna

Jason Vigna defends public companies and their personnel against shareholder litigation. Representing clients in courts throughout the country and before the Securities and Exchange Commission, he makes securities class actions the focus of his practice. His concentration in the area has made him both effective and efficient, as demonstrated by his long list of early case dismissals.

Resolving federal and state securities disputes

Representing public companies of all sizes, Jason has particular experience advising life sciences, financial services and technology companies. In addition to representing them in general complex commercial litigation, he helps these businesses, as well as their directors and officers, 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.

Jason brings to his clients an understanding not only of securities law, but also of their businesses. His knowledge of pharmaceutical, financial services and other industries gives him a common language with his clients and greater insight into the legal strategies that will work for them. Among other successes, he has had numerous victories in litigation arising from Bernard Madoff's Ponzi scheme. He successfully defended an asset manager and its employees in more than 50 derivative, bankruptcy and individual actions arising from Madoff-related investments, as well as a global financial services company against multibillion-dollar RICO and bankruptcy clawback claims brought by the trustee of the Madoff estate.

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