Appellee-plaintiff recovered a $15,000 judgment against the United States under the Federal Tort Claims Act, 28 U. S.C. §§ 1346(b), 2671 et seq. The award was for injuries sustained in the operation of a power saw while he was engaged in work on a prison construction crew as a federal prisoner in a federal correctional institution. The trial court concluded that such recovery was proper under United States v. Muniz, 374 U. S. 150, 83 S.Ct. 1850, 10 L.Ed.2d 805. *939 After the judgment was entered, the Supreme Court of the United States held in United States v. Demko, 385 U.S. 149, 87 S.Ct. 382, 17 L.Ed.2d 258, that the compensation benefits provided by 18 U.S.C. § 4126 constitute the exclusive remedy for injuries received by federal prisoners while performing assigned prison tasks. That decision precludes recovery under the Federal Tort Claims Act in the instant case.

The judgment is reversed and the case remanded with directions to dismiss the action.
