United States Forest Service v. Cowpasture River Preservation Assn.
Decided June 15, 2020. Clarence Thomas delivered the opinion of the Court.
Docket 18-1584 · 590 U.S. ___ (2020)
Holding
Because the Department of the Interior’s decision to assign responsibility over the Appalachian Trail to the National Park Service did not transform the land over which the Trail passes into land within the National Park System, the Forest Service had authority under the Mineral Leasing Act to grant a natural-gas pipeline right-of-way through lands in the George Washington National Forest traversed by the Appalachian Trail.
