The False Claims Act (31 U.S.C. §§ 3729–3733, also called the “Lincoln Law“) is an American federal law that imposes liability on persons and companies (typically federal contractors) who defraud governmental programs. The law includes a “qui tam” provision that allows people who are not affiliated with the government to file actions on behalf of the government (informally called “whistleblowing“). Persons filing under the Act stand to receive a portion (usually about 15–25 percent) of any recovered damages. Claims under the law have typically involved health care, military, or other government spending programs, and dominate the list of largest pharmaceutical settlements. The government has recovered nearly $22 billion under the False Claims Act between 1987 (after the significant 1986 amendments) and 2008.
