The applicable statute of limitations depends on the circumstances of a particular case. The False Claims Act contains two limitation periods that apply to an action brought under 31 U.S.C.S. § 3730. In Cochise Consultancy, Inc. v. U.S. ex rel. Hunt, 139 S. Ct. 1507 (2019), the Supreme Court held that in action filed by a qui tam plaintiff in which the government does not intervene, the suit must be brought within either (i) six years after an FCA violation occurred under 31 U.S.C. § 3731(b)(1) or (ii) three years after the United States official charged with the responsibility to act knew, or should have known, of the relevant facts, whichever period is longer. In no circumstance can an action be brought more than 10 years after a violation occurred.
