Qui tam
From Wikipedia, the free encyclopedia
Qui tam is a provision under the False Claims Act (31 U.S.C. § 3729 et seq.), which allows for a private individual, or whistleblower with knowledge of past or present fraud on the United States federal government to bring suit on behalf of the government. Its name is an abbreviation of the Latin phrase “qui tam pro domino rege quam pro se ipso in hoc parte sequitur,” meaning “he who [sues] for the king as well as for himself." This provision allows a private person, known as a “relator,” to bring a lawsuit on behalf of the United States, where the private person has information that the named defendant has knowingly submitted or caused the submission of false or fraudulent claims to the United States. The relator need not have been personally harmed by the defendant’s conduct.
A private [natural] person may not be able to commence a qui tam action "pro se" -- that is, without representation by a lawyer -- since the private person is actually representing/filing the suit on behalf of the government and that may only be done by a lawyer.
