Title 31 › SUBTITLE III — FINANCIAL MANAGEMENT › CHAPTER 37 — CLAIMS › SUBCHAPTER III — CLAIMS AGAINST THE UNITED STATES GOVERNMENT › § 3731
A subpoena for a witness in a related trial or hearing can be served anywhere in the United States. A civil false-claims case must be filed no later than 6 years after the wrongdoing, or within 3 years after a responsible U.S. official knew or should have known the key facts, but in any case not more than 10 years after the wrongdoing — whichever date is later. If the government joins the case it can file or amend the complaint and add claims. The government’s claim counts back to the original filing date when it comes from the same conduct. The United States must prove its case by a preponderance of the evidence. A final criminal conviction for fraud or false statements, whether by trial or by guilty/no contest plea, stops the defendant from denying those elements in a related civil case.
