Whistleblower Law Collaborative
Whistleblower Law Collaborative LLC, based in Boston, devotes its practice entirely to representing clients nationwide in bringing actions under the federal and state False Claims Acts and other whistleblower programs. Under the False Claims Act, a private citizen (known as a “relator”) who suspects or knows of fraud against the government can act as a whistleblower and file a sealed complaint on behalf of the government. Successful cases entitle the relator to a share of the government’s recovery. Among the firm’s many successes is the governments’ $465 million settlement with Mylan.
