The Facts

The U.S. government contracted with W.A. Ross Construction Co. to build dikes on the Missouri River as part of a federal river improvement project authorized by Congress. The construction caused erosion that destroyed Yearsley's property along the riverbank. Yearsley sued Ross Construction for damages. The lower courts ruled against Yearsley, and the case reached the Supreme Court.

The Issue

• Whether a private contractor acting under valid federal government authorization shares the sovereign immunity of the United States. • Whether a contractor can be held liable in tort for property damage caused while performing work expressly authorized and directed by Congress and the federal government.

The Rules

Yearsley v. W.A. Ross Construction Co., 309 U.S. 18 (1940) Government Contractor Immunity Doctrine

A contractor performing work authorized by valid federal legislation and directed by the government is not personally liable for damages resulting from that work; the contractor shares the sovereign immunity of the United States.

U.S. Const. Art. I, § 8, cl. 3 & cl. 18 Congressional Authority Over Commerce and Navigable Waters

Congress has authority to regulate commerce among the states and to make all laws necessary and proper for carrying that power into execution, including authorizing federal river improvement projects.

Rivers and Harbors Act of 1899, 33 U.S.C. § 401 et seq. Federal Authorization for River and Harbor Improvements

Federal law authorizes the Army Corps of Engineers and its contractors to undertake navigable waterway improvement projects; work performed pursuant to this authorization carries the force of federal sovereign direction.

The Application

History

Here, the Court applied the immunity doctrine to find that Ross Construction, acting under express federal authorization from the government to construct the Missouri River dikes as part of a congressionally-authorized public works project, shared in the sovereign's immunity despite causing property damage. Because the United States had valid constitutional authority for the river improvement project and had expressly directed Ross to perform the construction work, Ross could not be held liable in state tort for damages resulting from that authorized activity: even though private citizens suffered injury. The contractor's immunity flowed directly from the government's authorization and the contractor's compliance with federal direction, shielding Ross from Yearsley's claim regardless of the negligence or foreseeability of the erosion damage. This established that a contractor implementing a sovereign act loses the usual recourse available in private tort law when that act has been validly authorized and directed by the federal government.

The Conclusion

The Supreme Court unanimously held that where the government has validly conferred authority on a contractor to perform work, and the contractor acts within that authority, the contractor cannot be held liable for resulting damages the contractor shares the sovereign's immunity. The Court reasoned that if the government itself could not be sued for the authorized action, its agent acting under that authority likewise cannot be held liable. This principle became foundational for the government contractor defense in later cases.

Case Analysis

Overview

SCOTUS held that a government contractor is immune from liability when performing work authorized by valid congressional action and directed by the federal government.

Facts

The U.S. government contracted with W.A. Ross Construction Co. to build dikes on the Missouri River as part of a federal river improvement project authorized by Congress. The construction caused erosion that destroyed Yearsley's property along the riverbank. Yearsley sued Ross Construction for damages. The lower courts ruled against Yearsley, and the case reached the Supreme Court.

Issue

Whether a private contractor performing authorized federal public works projects is insulated from state tort liability for damages caused to private landowners by the contractor's construction activities conducted pursuant to federal authorization.

Rule

Yearsley v. W.A. Ross Construction Co., 309 U.S. 18 (1940), held that when the United States acts within its constitutional authority and expressly authorizes a contractor to undertake specific construction work, the contractor shares in the government's immunity from state tort claims for those authorized acts. The doctrine rests on the principle that a contractor cannot be held liable for lawfully implementing the federal government's sovereign decisions. Yearsley immunity is narrower than the Boyle defense and applies when the contractor acts under direct federal authorization rather than government-approved design specifications.

Analysis

Here, the Court applied the immunity doctrine to find that Ross Construction, acting under express federal authorization from the government to construct the Missouri River dikes as part of a congressionally-authorized public works project, shared in the sovereign's immunity despite causing property damage. Because the United States had valid constitutional authority for the river improvement project and had expressly directed Ross to perform the construction work, Ross could not be held liable in state tort for damages resulting from that authorized activity. Even though private citizens suffered injury. The contractor's immunity flowed directly from the government's authorization and the contractor's compliance with federal direction, shielding Ross from Yearsley's claim regardless of the negligence or foreseeability of the erosion damage. This established that a contractor implementing a sovereign act loses the usual recourse available in private tort law when that act has been validly authorized and directed by the federal government.

Conclusion

**The Supreme Court unanimously held that where the government has validly conferred authority on a contractor to perform work, and the contractor acts within that authority, the contractor cannot be held liable for resulting damages. The contractor shares the sovereign's immunity.** The Court reasoned that if the government itself could not be sued for the authorized action, its agent acting under that authority likewise cannot be held liable. This principle became foundational for the government contractor defense in later cases.

Notes

309 U.S. 18 (1940). Establishes two-part derivative sovereign immunity test for government contractors. Related to Geo Group v. Menocal.
