The False Claims Act has statutes of limitations like other laws that apply to the underlying fraud and apply separately to the anti-retaliation provisions. They are fairly straightforward with respect to the law, although there is one aspect of it that is a little unusual.
The Federal law currently has a so-called right of repose, which can extend the statute of limitations for underlying fraud up to 10 years under certain circumstances when the federal government was not aware of the fraud for three years. Generally, the statute of limitations for fraud under the act is six years, , but an additional right for the whistleblower to sue for their own damages, if they have been the subject of retaliation is three years.
The Qui Tam rights also are contingent upon filing the case under seal, which is a little unusual, and allowing the government to review the case and investigate the allegations itself prior to the government making a decision as to whether they want to intervene in the case.
