An appeals court has sided with backers of a Utah crude oil train that became the centerpiece of a recent Supreme Court battle over the scope of federal climate reviews for major projects.

In a short order Friday, the U.S. Court of Appeals for the District of Columbia Circuit granted a motion to require the Surface Transportation Board to further explain its authorization for the rail project — without scrapping the underlying approval.

The three judges overseeing the case — Patricia Millett, Cornelia Pillard and Robert Wilkins, all Obama appointees — had previously ruled to toss out the board’s authorization of the Uinta Basin Railway for falling short of requirements under the National Environmental Policy Act to study the project’s impacts.
