United States v. Winstar Corp., 518 U.S. 839 (1996) (U.S. Supreme Court)
United States v. Winstar Corp.
Is the United States liable for breach of its thrift-assistance contracts when subsequent legislation (FIRREA) prevents performance of promised regulatory accounting treatment for supervisory goodwill, or do the unmistakability and sovereign acts doctrines shield the government from liability?
Ordinary principles of contract law apply to the United States when it acts in its proprietary capacity. The unmistakability doctrine, which requires clear and unmistakable terms to find a surrender of sovereign authority, does not bar claims seeking damages for breach based on the government's assumption of risk; it primarily prevents construing a public contract as an exemption from future regulation absent unmistakable terms. The sovereign acts doctrine shields the United States from liability when a public and general act of the sovereign renders performance impossible and the contract did not allocate the risk of such governmental action to the United States. However, when the government expressly or impliedly assumes the risk of regulatory change—such as by promising specific regulatory treatment—subsequent public and general legislation does not preclude contract liability; the government may legislate, but it must pay damages for breaching its contractual commitments.
Yes. The United States is liable for breach of the thrift-assistance contracts. The unmistakability doctrine does not bar recovery because the plaintiffs sought damages for breach rather than an exemption from regulation, and the agreements allocated to the government the risk of regulatory change. The sovereign acts doctrine also does not preclude liability because, even if FIRREA was a public and general act, the government assumed the risk that such action would interfere with promised regulatory treatment and is therefore responsible for damages.
Winstar is the leading case on government liability when later sovereign acts frustrate contractual commitments. It clarifies that: - The government cannot invoke the unmistakability doctrine to avoid damages where a contract allocates regulatory risk to the government; that doctrine primarily bars reading public contracts as regulatory exemptions. - The sovereign acts doctrine does not provide blanket immunity; if the government assumed the risk of regulatory change, it remains liable for breach even when the change results from public and general legislation. - Ordinary contract principles—including expectancy damages—apply to the United States acting as contractor. Agencies must draft with care (e.g., include change-in-law clauses or explicit risk allocations) and recognize that inducements based on regulatory treatment can generate substantial liability if later law changes upset that bargain. For law students, Winstar is a cornerstone for understanding sovereign capacity versus contractual capacity, risk allocation in public contracts, and the limits of government defenses in the face of legislative change. It also spawned a major line of follow-on damages cases ("Winstar-related cases") that shaped remedies against the United States.
