LEON HARRIS, CNN ANCHOR: Let's go now to Washington and our Jeanne Meserve, who's got some breaking news for us now -- Jeanne.</s>JEANNE MESERVE, CNN ANCHOR: Leon, a blow for the trucking industry today and a boost for environmentalists. The U.S. Supreme Court has ruled that the Federal Clean Air Act, when setting standards for that, the EPA does not have to consider matters of cost. Charles Bierbauer, I understand, is now at the court for us. Charles, what can you tell us about this ruling?</s>CHARLES BIERBAUER, CNN SR. JUSTICE CORRESPONDENT: Good morning, Jeanne. Well, this was a dispute between the American Trucking Association, among others on the business and corporate side, and the Environmental Protection Agency. The questions before the court were complex, and so is the ruling. But the underlying decision by the court is unanimous, and that is that Congress did not overstep its bounds in allowing the Environmental Protection Agency to regulate and set the standards for particulate matter -- soot and ozone emissions. And in so doing, the court found that that was a proper delegation by Congress to the Environmental Protection Agency. And it also said, knocking down the argument by the Trucking Association, that the EPA should not have to consider the cost of compliance; that, above all, as Justice Antonin Scalia, speaking for the majority, writing for them, said, the standards must protect the health with the "requisite" amount of safety, and the cost is not a consideration. However, the court did go on to the find that the compliance guidelines set by the EPA were themselves unlawful in that the EPA would have to go back, revisit those compliance standards and rewrite them. In fact, the EPA is already in the process of revising its standards, so that's something that would have come into effect pretty much anyhow -- Jeanne.</s>MESERVE: Charles Bierbauer with the latest from the U.S. Supreme Court. Leon, now back to you in Atlanta.</s>HARRIS: All right, thank you, Jeanne.
