Oral argument before the Supreme Court focused on the question of when the EPA must take account of costs. The states pressing the suit say the law requires the calculation to take place right off the bat, when the agency is deciding whether to develop standards. Donald Verrilli, the solicitor-general (backed by some other states and power firms), said that taking account of costs could wait until the stage when regulatory standards were spelled out-allowing the EPA to include those "co-benefits”.
