Seven County Infrastructure Coalition v. Eagle County

Decided May 29, 2025. Brett M. Kavanaugh delivered the opinion of the Court.

Docket 23-975 · 605 U.S. 168 · Cited 12 times

The D. C. Circuit failed to afford the U. S. Surface Transportation Board the substantial deference required when reviewing agency action under the National Environmental Policy Act, and incorrectly interpreted NEPA to require the Board to consider in its environmental impact statement the environmental effects of temporally and geographically separate upstream and downstream projects unrelated to the Uinta Basin Railway.
