Law Firm Overview

Nationwide Whistleblower Law Firm 

Phillips & Cohen LLP is the nation’s most successful law firm representing whistleblowers. Its cases have resulted in governments recovering more than $11 billion in civil settlements and criminal fines, and its whistleblower clients have received more than $730 million in rewards.

The law firm represents whistleblowers in “qui tam” cases brought under the False Claims Act and whistleblower claims filed under the Internal Revenue Service, the Securities and Exchange Commission and the Commodity Futures Trading Commission whistleblower reward programs.

Phillips & Cohen whistleblower cases have helped bring about many record-setting settlements:

Phillips & Cohen attorneys have received many accolades for their work on behalf of whistleblowers. The law firm and its attorneys have been named to highly selective lists such as:

Attorney John R. Phillips, a founding partner (now retired), worked closely with Congress to strengthen and pass the False Claims Act Amendments of 1986, which created the modern whistleblower reward program to encourage private citizens to expose fraud against the government. Claire M. Sylvia, another partner, is the author of The False Claims Act: Fraud Against the Government (West, 2010), a leading treatise on the False Claims Act and its qui tam (whistleblower) provisions.

Phillips & Cohen’s roster also includes former government fraud prosecutors, a former U.S. Senate Judiciary counsel, a former U.S. Attorney and experienced litigators recruited from the nation’s top law firms.

Because of our extensive record of success and the depth of our experience with whistleblower cases, the New York Times, The Wall Street Journal, Bloomberg News, "60 Minutes" and other news media often contact Phillips & Cohen attorneys for expert opinions on whistleblower matters. Our attorneys also have written many articles and op-eds about whistleblower laws and programs.
