Aaron Rubinstein is a partner in the Litigation Department and head of the Financial Services Litigation Practice. Aaron recently completed a twelve-year term as chair of the Litigation Department. He has 40 years of experience representing defendants and plaintiffs in complex commercial litigations, including securities, commodities, derivatives and contract claims. He handles both private suits, including class actions and shareholder derivative actions, and proceedings before government enforcement agencies. His representations have been of a wide variety of clients, including public and privately held corporations, directors of such companies, individuals, and some of the largest financial institutions, both domestic and international.

Aaron was the lead trial counsel in the longest civil jury trial in the Federal Court of the Southern District of New York, lead counsel in the representation of mg technologies ag (now GEA Group AG), the German conglomerate, and its subsidiaries in numerous securities, shareholder derivative and derivatives-related actions arising out of mg’s nearly $2 billion of losses in derivatives contracts, and the lead trial counsel representing one of the largest state-owned corporations of the People’s Republic of China in a derivatives-related trial in the Southern District of New York. He was the lead litigation counsel for a global financial institution in its Enron-related litigation, in which he obtained sweeping victories dismissing all of the more than $400 million of claims against the client and granting the client judgment on its counterclaims in an amount exceeding $400 million.

Aaron has been recognized as a leading lawyer by Chambers USA (NY: Litigation General Commercial), which quoted clients who noted that he is “‘a brilliant man” (2015) and a “‘safe pair of hands’” (2014) with an “‘intelligent, thoughtful and tenacious’ approach to advocacy’” (2013). Clients praise Aaron as “‘an excellent big-picture strategist’” with a “‘complete command of all the details’” (2010). Clients also noted that he “‘puts a lot of energy into his thoughts and recommendations’” and carries a deep knowledge of “‘federal and state law procedure’” (2012). Aaron has also been recognized as a leading commercial litigator by Who’s Who Legal and Best Lawyers. In addition, Benchmark Litigation 2014 ranks Aaron as a National and Local Litigation Star in Commercial Litigation.
