Gary Thacker, et ux. v. Tennessee Valley Authority

Updated Sep 5, 2026

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.

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?
