The Bush administration and the coal industry will have to wait another four months to argue their appeal of the latest federal court ruling to curb mountaintop removal coal mining. Oral arguments before the 4th U.S. Circuit Court of Appeals in Richmond, Va., have been delayed until late September. Arguments had been set for May 13 in the appeal of two 2007 rulings by U.S. District Judge Robert C. Chambers. Bill Raney, president of the West Virginia Coal Association, said it was too soon to say if the delay would cause problems for companies that have agreed to put off moving into new valley fills until the case is heard. But Raney said the industry is anxious to have the appeal decided. "I think you perpetuate the uncertainty that I think everybody would like to get behind them," Raney said. Coal industry lawyers and the U.S. Army Corps of Engineers are appealing the rulings, which required more thorough review by the corps of new mountaintop removal Clean Water Act permits. On Wednesday evening, the 4th Circuit issued a one-paragraph order rescheduling the arguments until the court's next session Sept. 23-26. The order cited "reasons appearing to the court," and did not offer any further explanation. Patricia Connor, clerk of the court, cited an unspecified "scheduling issue" as the reason for the change. Connor said a three-judge panel for the case had already been chosen, and it is not clear if a new panel will be picked for the rescheduled argument. Panel selection for mountaintop removal cases has become controversial, after the same two conservative judges - Paul V. Niemeyer and J. Michael Luttig - ended up on panels that overturned three previous district court rulings aimed at limiting the mining practice. Appeals court panels are supposed to be chosen randomly. Three-judge panels are chosen ahead of time, but not publicly announced until the morning of argument hearings. After the third appeal was heard, the court revealed that at least five of the court's 13 judges had recused themselves because of financial interests in the case. Since then, Luttig has left his lifetime appointment to the court. He resigned in 2006 to take a job as general counsel for Boeing, after being passed over by President Bush for two open Supreme Court slots. Connor refused Thursday to say if any of the current judges have recused themselves from the latest mountaintop removal appeal. The two West Virginia judges on the 4th Circuit, Robert B. King and M. Blane Michael, have never served on an appeals panel in a mountaintop removal case. But in February 2006, King and Michael joined in a dissent when the full 4th Circuit declined to rehear one of the appeals. "This case is of exceptional importance to the nation, and in particular, to the states of the Appalachian region," the dissent said. "The Appalachian mountains, the oldest mountain chain in the world, are one of the nation's richest, most diverse, and most delicate ecosystems, an ecosystem that the mountaintop removal coal mining authorized by the corps' general permit may irrevocably damage."
