Chevron USA Inc. v. Plaquemines Parish

Chevron USA Inc. v. Plaquemines Parish, 608 U.S. ____ (2026), was a United States Supreme Court case involving the removal jurisdiction for a lawsuit brought by several parishes in Louisiana against Chevron and ExxonMobil over violations of the state's environmental protections, which had been shown to contribute to the loss of wetlands along the Louisiana coastline. After the parishes had won their case in state courts and penalizing the companies with a $745 million fine, Chevron moved to argue that the case should have been held in federal courts. The Supreme Court agreed in an 8–0 decision, determining that Chevron had shown that their crude oil production was connected to their aviation fuel production during World War II under federal government contracts, and thus should be under jurisdiction of federal courts.
