Luke Cadigan is an experienced trial attorney and litigator. Mr. Cadigan concentrates his practice on securities enforcement matters, internal investigations, regulatory compliance, and related litigation.
Professional BackgroundPrior to joining K&L Gates, Mr. Cadigan was an Assistant Director in the Enforcement Division of the Securities and Exchange Commission, serving that role in both the Boston Regional Office and in the SEC’s Foreign Corrupt Practices Act Unit. He managed investigations conducted by staff attorneys and accountants into, among other things, matters relating to investment advisers, broker-dealers, insider trading, accounting fraud, offering fraud, and whistleblower complaints. Mr. Cadigan also oversaw investigations into potential FCPA violations and, serving as a member of the agency’s Cross Border Working Group, he supervised investigations into the accounting practices of Chinese and other foreign companies trading on U.S. markets. Before becoming an Assistant Director, Mr. Cadigan spent more than seven years as Senior Trial Counsel at the SEC. In that role, he investigated and litigated dozens of high-profile matters. As lead counsel, he also successfully tried several complex matters, both in federal court and the SEC’s administrative forum. These matters related to, among other things, allegations of insider trading by a hedge fund employee, accounting fraud, a pay-to-play scheme by a former state senate majority leader, fraud by an investment adviser, and fraud by a broker-dealer (resulting in then the largest penalty awarded in an SEC administrative proceeding). He was a recipient of the Chairman’s Award for Excellence in 2002 and 2007 and the Division of Enforcement Director’s Award in 2007 and 2008. Before joining the SEC, Mr. Cadigan was a senior associate at another law firm in Boston, focusing his practice on government enforcement and complex commercial litigation. He also served as a law clerk for the Honorable Edward F. Harrington of the United States District Court in Massachusetts and as a Special Assistant District Attorney in Middlesex County, Massachusetts.
