No. 24-924Apr 22, 2026Armed Forces and National SecurityReversed

The question

Whether federal law preempts a soldier's state-law tort claims against a military contractor when the Federal Government neither ordered nor authorized the contractor's challenged conduct.

Hencely v. Fluor Corp.

What the Court decided

The Court reversed the Fourth Circuit and held that Hencely's state-law tort claims against Fluor are not preempted. The Federal Government neither ordered nor authorized Fluor's challenged conduct, and neither the Constitution nor any federal statute expressly preempts the suit. The Court found the Fourth Circuit's reliance on Boyle misplaced because Boyle involved a procurement contract rather than a performance contract and requires a significant conflict between state law and an identifiable federal policy or interest.

The Court's opinion

Thomas, joined by Sotomayor, Kagan, Gorsuch, Barrett, Jackson

The Fourth Circuit erred in finding Hencely's claims preempted because the Federal Government neither ordered nor authorized Fluor's conduct. No constitutional provision or federal statute expressly preempts the suit, and the Supremacy Clause requires state law to yield only when it conflicts with the Constitution or a valid federal statute or treaty. The FTCA's combatant-activities exception does not itself apply to suits against federal contractors. Boyle does not support the preemption rule because it involved a procurement contract rather than a performance contract, did not involve the combatant-activities exception, and displaces state law only when there is a significant conflict with an identifiable federal policy or interest.
