TVA immunity from lawsuits
Gary Thacker, et ux. v. Tennessee Valley Authority
In brief
The TVA cannot use the Federal Tort Claims Act's discretionary-function exception to end the Thackers' suit.
- Where it stands
- Decided
Decided 9-0 · April 29, 2019 · Opinion by Justice Kagan
- What it’s about
- The Court unanimously ruled for the Thackers, holding that the TVA’s broad authority to “sue and be sued” is not limited by the Federal Tort Claims Act’s discretionary-function exception.
- Who it affects
- People claiming the TVA acted negligently may have a path to court rather than being blocked by that exception. For example, the Thackers can continue their claim involving a downed power line in the Tennessee River.
Summary: written with AI from the case record.

What it's about
It sent the case back for the lower courts to decide whether the alleged negligence was commercial or governmental and, if governmental, whether allowing the suit would gravely interfere with the TVA’s governmental work.
The decision defines when a federally created agency with authority to “sue and be sued” can be sued for alleged negligence.
Question presented
1. This Court tests the immunity of governmental "sue and be sued" entities (like the Tennessee Valley Authority) under Fed. Housing Amin. v. Burr , 309 U.S. 242 (1940). The Court has declined to borrow rules from the Federal Tort Claims Act (FTCA) to narrow that immunity. FDIC v. Meyer , 510 U.S. 471 (1994). Did the Eleventh Circuit err by using an FTCA-derived "discretionary-function exception," rather than Burr , to immunize the TVA from the plaintiffs' claims? 2. Did the Eleventh Circuit, in any case, correctly apply the discretionary-function test? Did that court correctly hold that safely raising a downed power line from the Tennessee River constitutes the sort of "policy"-laden discretionary work that this exception was designed to immunize from suit?
What the Court decided
Holding
The waiver of immunity in the TVA’s sue-and-be-sued clause is not subject to a discretionary function exception of the kind in the FTCA. By the terms of the Tennessee Valley Authority Act of 1933, the TVA’s sue-and-be-sued clause contains no exception for suits based on discretionary functions. Nor does the FTCA’s discretionary function exception apply to the TVA. See 28 U. S. C. §2680( l ). But this Court recognized in Federal Housing Administration v. Burr, 309 U. S. 242, that a sue-and-be-sued clause might be subject to an “implied restriction,” id., at 245.

The vote
What's next
The case returns to the lower courts. They must decide whether the alleged negligence was commercial or governmental and, if governmental, whether the suit would gravely interfere with the TVA's governmental work.
