When Federal Contractor Immunity Has Limits: The Supreme Court’s Decision in Hencely v. Fluor
The Supreme Court’s decision in Hencely v. Fluor Corp. is an important reminder that federal contractor status is not a blanket shield from state-law tort liability, even in the military contracting context. The case arose from a 2016 suicide bombing at Bagram Airfield in Afghanistan. Ahmad Nayeb, an Afghan national working for a Fluor subcontractor under the military’s “Afghan First” initiative, detonated a suicide vest after being confronted by Army Specialist Winston Hencely. Hencely was severely injured and later sued Fluor under South Carolina law for negligent supervision, negligent entrustment, and negligent retention. The Army’s own investigation found that Fluor had failed to comply with base procedures governing the supervision and escorting of local national workers.
The Fourth Circuit had affirmed summary judgment for Fluor under a broad theory sometimes described as “battlefield preemption.” In that court’s view, state-law claims against military contractors integrated into combatant activities under military command were preempted, even where the contractor allegedly violated military instructions. The Supreme Court rejected that rule. Writing for the Court, Justice Thomas emphasized that neither the Constitution nor any federal statute expressly preempted Hencely’s claims, and the Federal Tort Claims Act’s combatant-activities exception protects the federal government, not automatically its contractors.
The Court’s treatment of Boyle v. United Technologies Corp. is central. Boyle protects contractors in limited circumstances where the government directed the precise conduct being challenged and state law would create a significant conflict with federal policy. But Hencely was different. The allegation was not that Fluor faithfully executed a military command that state law later second-guessed. The allegation was that Fluor failed to follow the government’s own contractual and base-security requirements. On that theory, state tort law did not conflict with federal direction; it reinforced the contractor’s duty to comply with it.
For federal government contractors, the implication is practical and significant. Preemption and derivative immunity defenses remain important, but they are strongest when the contractor can show that the government specifically authorized, required, or controlled the challenged conduct. They are weakest where the alleged injury flows from noncompliance, poor supervision, subcontractor failures, inadequate training, or disregard of contractually imposed safety or security procedures. Contractors operating in contingency environments should therefore treat government direction, written procedures, escort policies, access controls, subcontractor oversight, and employee discipline as litigation-critical records, not merely operational requirements.
The decision also has implications beyond military contracting. It reinforces a broader principle: performing federal work does not transform a private contractor into the sovereign. Contractors may benefit from federal defenses when they are executing the government’s will, but they remain accountable for their own conduct unless Congress has provided a specific statutory immunity or claims-channeling regime. The case therefore narrows broad battlefield-preemption theories and heightens the importance of documented compliance with government instructions.
The dissent warned that allowing such claims may invite discovery into sensitive military judgments and risk state-law intrusion into wartime decision-making. That concern may shape future litigation, particularly where contractor conduct is closely intertwined with military discretion. But the majority’s rule places the dividing line at authorization and control. If the government ordered the challenged act, the contractor has a stronger defense. If the contractor departed from government instructions, immunity is far less certain.
