Qui tam action

Definition

In a qui tam action, a private party called a relator brings an action on the government's behalf. The government, not the relator, is considered the real plaintiff. If the government succeeds, the relator receives a share of the award. Also called a popular action.

For example, the federal False Claims Act authorizes qui tam actions against parties who have defrauded the federal government. 31 U.S.C. § 3279 et seq. If successful, a relator in a False Claims Act qui tam action may receive up to 30% of the government's award. 

Illustrative caselaw

See, e.g. United States ex rel Eisenstein v. City of New York, 129 S.Ct. 2230 (2009).

If successful, the plaintiff ll be entitled to a percentage of the recovery of the penalty as a reward for exposing the wrongdoing and recovering funds for the government.
