The Facts

Boyle was injured while piloting a military helicopter manufactured by United Technologies Corp. He sued the contractor in tort, alleging the helicopter's design was defective and dangerous. The trial court denied the contractor's motion to dismiss, and the case proceeded based on state tort law. The question arose whether federal law preempts state tort claims against military contractors for government-approved designs.

The Issue

Whether state tort law claims against a military contractor for design defects in military equipment are preempted by federal law when the government has approved the design specifications. Whether the federal government's approval of military equipment design provides a contractor with immunity from state tort liability.

The Rules

Boyle v. United Technologies Corp., 487 U.S. 500 (1988) Federal Preemption of Military Contractor Tort Liability

State tort law is preempted by federal common law when a contractor is sued for design defects in military equipment approved by the government, the contractor warned of dangers, and the design was specified by the government.

U.S. Const. art. III, cl. 2 Federal Question Jurisdiction

Federal courts have jurisdiction over cases arising under the Constitution, laws, and treaties of the United States, supporting federal preemption of state law in matters of federal importance.

Supremacy Clause, U.S. Const. art. VI, cl. 2 Preemption Doctrine

Federal law preempts conflicting state law where Congress has occupied a field or where state law conflicts with federal interests, including national defense and military procurement.

The Application

History

Applying the three-part Boyle test, the Court examined whether the government had approved the helicopter's specifications, whether United Technologies' design conformed to those specifications, and whether the contractor had adequately warned the government of known hazards in the design. Because the military had actively participated in approving the helicopter's design specifications and United Technologies had complied with those government-directed specifications, the federal contractor defense displaced Boyle's state tort claims, even though the design may have been defective under traditional tort standards. The Court reasoned that allowing state tort suits against military contractors for government-approved designs would undermine federal procurement policy by exposing contractors to conflicting state-law obligations that could impair their ability to fulfill defense missions. Thus, federal common law, not state tort law, governed the contractor's liability in this context.

The Conclusion

**The Supreme Court held 5-4 that federal common law preempts state tort claims against military contractors when (1) the relevant military equipment was approved by the government, (2) the contractor warned the government of known dangers, and (3) the design was inherent to the government's requested specifications.** This established a qualified immunity doctrine protecting military contractors from state tort suits where the government actively participated in design decisions.

Case Analysis

Overview

The Supreme Court held that contractors cannot be sued in tort for design defects in military equipment when the government approved the specifications.

Facts

Boyle was injured while piloting a military helicopter manufactured by United Technologies Corp. He sued the contractor in tort, alleging the helicopter's design was defective and dangerous. The trial court denied the contractor's motion to dismiss, and the case proceeded based on state tort law. The question arose whether federal law preempts state tort claims against military contractors for government-approved designs.

Issue

Whether the federal government contractor defense preempts state tort law claims against a private contractor for injuries occurring at a federal facility, and whether the contractor's compliance with government specifications establishes the defense.

Rule

Boyle v. United Technologies Corp., 487 U.S. 500 (1988), preempts state tort law as applied to government contractors when the three-part Boyle test is satisfied: the government approved the specifications, the product conformed to them, and the contractor warned the government of known hazards. Federal procurement law creates a unique relationship between the government and its contractors that may displace state tort liability to ensure contractors can adequately perform federal missions without exposure to inconsistent state-law obligations.

Analysis

Applying the three-part Boyle test, the Court examined whether the government had approved the helicopter's specifications, whether United Technologies' design conformed to those specifications, and whether the contractor had adequately warned the government of known hazards in the design. Because the military had actively participated in approving the helicopter's design specifications and United Technologies had complied with those government-directed specifications, the federal contractor defense displaced Boyle's state tort claims. Even though the design may have been defective under traditional tort standards. The Court reasoned that allowing state tort suits against military contractors for government-approved designs would undermine federal procurement policy by exposing contractors to conflicting state-law obligations that could impair their ability to fulfill defense missions. Thus, federal common law, not state tort law, governed the contractor's liability in this context.

Conclusion

**The Supreme Court held 5-4 that federal common law preempts state tort claims against military contractors when (1) the relevant military equipment was approved by the government, (2) the contractor warned the government of known dangers, and (3) the design was inherent to the government's requested specifications.** This established a qualified immunity doctrine protecting military contractors from state tort suits where the government actively participated in design decisions.
