Constantine Cannon

With offices in New York, Washington, D.C., San Francisco and London, Constantine Cannon LLP is one of the largest and most successful whistleblower practices in the United States. The firm's team of dedicated whistleblower lawyers represent whistleblowers under federal and state False Claims Acts as well as the whistleblower programs of the IRS, SEC, CFTC, DOT, and others. In the financial arena, Constantine Cannon recently secured a multi-million-dollar SEC award for an anonymous whistleblower whose original information and assistance led to an enforcement action against brokerage firm ITG. In a separate case, the firm represented a whistleblower who provided extensive and ongoing assistance to the SEC in its investigation of a major international company. The depth of information provided to the SEC convinced the agency to increase the client's award to $1.7 million, an acknowledgment not only of the client's significant investigative assistance, but also the professional and financial risks the client took in bringing the misconduct to light. The SEC increases a whistleblower's award in fewer than 7% of cases. Beyond its Whistleblower practice, Constantine Cannon also has deep expertise in areas that include antitrust and complex commercial litigation, government relations, securities, and e-discovery. The firm's antitrust practice is among the largest and most well recognized in the nation. Constantine Cannon's experience spans multiple industries, including healthcare, banking, electronic payments, insurance, high tech, telecommunications, the Internet, and government contracting.
