The Congressional Research Service has released a report on the False Claims Act, Qui Tam: The False Claims Act and Related Federal Statutes. CRS is a department within the Library of Congress that provides policy and legal analysis to Congressional committees and members.
The report summarizes the history of the law, including the 2009 amendments. It outlines key provisions of the law: who may be liable, who may bring an action, basis for liability, penalties and awards, and procedure. Another section considers constitutional concerns that have been raised, such as due process, separation of powers, standing, and the appointments clause.
