The Facts

Hencely was injured while working at a federal facility being operated and managed by Fluor Corporation under a government contract. He filed state tort claims against Fluor for his injuries. Fluor moved to dismiss, asserting it was immune from suit because it was acting under the direct authorization and control of the federal government. The case required the court to determine the scope and applicability of the government contractor defense.

The Issue

• Whether the Yearsley doctrine immunizes a federal contractor from state tort liability when acting under validly conferred federal authority • Whether the Boyle defense preempts state tort claims against contractors who comply with reasonably precise government specifications • Whether the contractor's actions fell within the scope of federal authorization sufficient to trigger immunity

The Rules

309 U.S. 18 (1940) Yearsley v. W.A. Ross Construction Co.

A contractor acting pursuant to validly conferred federal authority is immune from state tort liability, provided the government validly authorized and directed the work.

487 U.S. 500 (1988) Boyle v. United Technologies Corp.

Federal law displaces state tort law as to government contractors when the government approved reasonably precise specifications, the equipment conformed to those specifications, and the contractor warned the government of known dangers.

28 U.S.C. § 1442 Federal Officer Removal Statute

Any civil action commenced in state court against any person acting under a federal officer may be removed to federal district court.

The Application

History

Fluor's operation of the federal facility under government contract placed it within the government contractor immunity framework, requiring the court to determine whether Hencely's injury resulted from conduct within the scope of federally authorized activity. The Boyle/Yearsley analysis required examining whether the federal government had approved or directed the operational practices that caused the injury if so, state tort liability would impose unanticipated costs on federal operations and frustrate the contractual bargain the immunity doctrine protects. This made the case turn on whether Fluor exercised delegated federal authority as the government authorized, rather than on product specifications, engaging the broader Yearsley immunity for contractor conduct rather than Boyle's narrower design-defect test.

The Conclusion

**The court analyzed the government contractor defense under both Yearsley v. W.A.** Ross Construction Co. and Boyle v. United Technologies Corp., examining whether Fluor acted pursuant to valid federal authorization. The court held that contractors acting within the scope of authority validly conferred by the federal government may be shielded from state tort liability. This case reinforced that the Yearsley doctrine provides a broad immunity when the government has authorized and directed the contractor's conduct, distinct from the more narrow Boyle defense applicable to design defects.
