Title 31 › Subtitle SUBTITLE III— - FINANCIAL MANAGEMENT › Chapter CHAPTER 37— - CLAIMS › Subchapter SUBCHAPTER III— - CLAIMS AGAINST THE UNITED STATES GOVERNMENT › § 3731
A court order that tells a witness to come to a trial or hearing in a false-claims lawsuit can be served anywhere in the United States. A private false-claims lawsuit must be filed no later than 6 years after the false act, or within 3 years after a responsible U.S. official knew or should have known the important facts, but in any case no more than 10 years after the false act. If the government joins the case, it can file or change the complaint and its claims will count as filed on the original plaintiff’s date for time-limit rules, but only for claims from the same conduct. In these cases the United States must prove every important part of the claim, including the amount of harm, by a preponderance of the evidence (more likely than not). If the government won a related criminal fraud or false-statement case (by trial verdict or a guilty/no-contest plea), the defendant cannot deny the essential parts of that crime in the related civil suit.
