32 CFR § 750.33 - Damages.
(a) Generally. The measure of damages is determined by the law of the place where the act or omission occurred. When there is a conflict between local and applicable Federal law, the latter governs. 28 U.S.C. 1346(b).
(b) Limitations on liability. The United States is not liable for interest prior to judgment or for punitive damages. In a death case, if the place where the act or omission complained of occurred provides for only punitive damages, the United States will be liable in lieu thereof, for actual or compensatory damages. 28 U.S.C. 2674.
(c) Setoff. The United States is not obligated to pay twice for the same injury. Claimants under the FTCA may have received Government benefits or services as the result of the alleged tort. The cost of these services or benefits shall be considered in arriving at any award of damages. For example, the cost of medical or hospital services furnished at Government expense, including TRICARE payments, shall be considered. Additionally, benefits or services received under the Veterans Act (38 U.S.C. 101-800) must be considered. Brooks v. United States, 337 U.S. 49 (1949).
(d) Suit. Any damage award in a suit brought under the FTCA is limited to the amount claimed administratively unless based on newly discovered evidence. 28 U.S.C. 2675(b). Plaintiff must prove the increased demand is based on facts not reasonably discoverable at the time of the presentment of the claim or on intervening facts relating to the amount of the claim.
