  • D.C. Circuit Denies Petitions for Full Court Review of Decision to Overturn CSAPR

    The U.S. Court of Appeals for the D.C. Circuit last week declined petitions for rehearing en banc of the Cross-State Air Pollution Rule (CSAPR). The federal court’s denial of the petitions leaves in place the Clean Air Interstate Rule (CAIR)—a Bush-era rule that the court had formerly invalidated in July 2008 and then reinstated. It also could prompt environmental groups, 15 states, and the Environmental Protection Agency (EPA) to take their case to the U.S. Supreme Court.
