Adam Prussin specializes in securities litigation and has extensive experience in derivative actions. He was special litigation counsel in the derivative actions on behalf of Summit Metals, Inc., actions which resulted in entry of a judgment, after trial, of $43 million in cash, plus an order transferring the stock of two multi-million-dollar companies to the plaintiff.

Adam has published several articles on the subject of the standards and procedures for the maintenance or dismissal of derivative actions, including Termination of Derivative Suits Against Directors on Business Judgment Grounds: From Zapata to Aronson, 39 Bus. Law. 1503 (1984); Dismissal of Derivative Actions Under the Business Judgment Rule: Zapata One Year Later, 38 Bus. Law. 401 (1983); and The Business Judgment Rule and Shareholder Derivative Actions: Viva Zapata?, 37 Bus. Law. 27 (1981). In June 2009 he spoke at the 6th Annual Securities Litigation Conference in New York, participating in the panel discussion, From Behind Enemy Lines: The Perspective of Two Prominent Plaintiff Attorneys.

Before joining the Firm, Adam was a named partner in Silverman, Harnes, Harnes, Prussin & Keller, which specializes in representing plaintiffs in shareholder derivative and class action litigation, particularly those involving self-dealing by corporate officers, directors and controlling shareholders. He played a key role in several landmark derivative cases in the Delaware courts, and has appeared frequently before the Delaware Supreme Court.

Adam graduated cum laude from Yale College in 1969 and, after obtaining a Master’s Degree from the University of Michigan in 1971, received his J.D. degree from Harvard Law School in 1974.

Adam is admitted to practice in New York, the United States District Courts for the Southern and Eastern Districts of New York, and the United States Courts of Appeals for the Second, Ninth and D.C. Circuits.
