Environmental Protection Agency v. Brown
Argued January 12, 1977
Decided May 2, 1977*
431 U.S. 99
This Court will not review judgments of the Courts of Appeals invalidating transportation control plan regulations promulgated by the Administrator of the Environmental Protection Agency under the Clean Air Act and imposed on various States as elements of an implementation plan where the federal parties have not only renounced an intent to seek review of the invalidation of certain regulations but have conceded that those remaining in controversy are invalid unless modified.
