The U.S. Supreme Court has rejected industry arguments, including those from trucking, that the federal government must consider cost and not just health benefits in setting national air pollution standards.

The case was brought by the American Trucking Associations and the U.S. Chamber of Commerce. In November the justices heard arguments about a pair of decisions that could affect not only engine emission requirements but the entire federal regulatory mechanism.
The justices also ruled against arguments that the Environmental Protection Agency took legislative power away from Congress when it set tougher clean air standards in 1997.

Washington Editor Oliver Patton will have a complete report on the decision tomorrow.
