Summary

When the United States is harmed in its business or property by something the antitrust laws forbid, it can sue in the U.S. district court where the defendant lives, is found, or has an agent. The United States can recover three times the damages it suffered plus the cost of the lawsuit. If the United States asks quickly, the court may also award simple interest on the actual damages from the day the U.S. served its complaint until judgment (or for a shorter time) if the court thinks that is fair. The court will look only at four things when deciding fairness: meritless or bad‑faith motions or claims that caused delay; violations of rules or orders about speedy process; conduct meant mainly to delay or raise costs; and whether interest is needed to compensate the United States.

Title 15, §15a

Commerce and Trade — Source: USLM XML via OLRC

Whenever the United States is hereafter injured in its business or property by reason of anything forbidden in the antitrust laws it may sue therefor in the United States district court for the district in which the defendant resides or is found or has an agent, without respect to the amount in controversy, and shall recover threefold the damages by it sustained and the cost of suit. The court may award under this section, pursuant to a motion by the United States promptly made, simple interest on actual damages for the period beginning on the date of service of the pleading of the United States setting forth a claim under the antitrust laws and ending on the date of judgment, or for any shorter period therein, if the court finds that the award of such interest for such period is just in the circumstances. In determining whether an award of interest under this section for any period is just in the circumstances, the court shall consider only—
(1)whether the United States or the opposing party, or either party’s representative, made motions or asserted claims or defenses so lacking in merit as to show that such party or representative acted intentionally for delay or otherwise acted in bad faith;
(2)whether, in the course of the action involved, the United States or the opposing party, or either party’s representative, violated any applicable rule, statute, or court order providing for sanctions for dilatory behavior or otherwise providing for expeditious proceedings;
(3)whether the United States or the opposing party, or either party’s representative, engaged in conduct primarily for the purpose of delaying the litigation or increasing the cost thereof; and
(4)whether the award of such interest is necessary to compensate the United States adequately for the injury sustained by the United States.
