Texas and Virginia filed a brief in the U.S. Court of Appeals for the District of Columbia Circuit May 20 contenting that the Environmental Protection Agency relied on material never subjected to public review when it denied petitions to reconsider its finding that greenhouse gas emissions endanger the public. The states asked the judges to rule that the EPA improperly denied their petitions to reconsider and to require that the document be subject to a new round of public notice and comment.
