The Supreme Court over-ruled one of the Obama administration’s environmental protections — an Environmental Protection Agency regulation that limits emissions of mercury and other pollution from coal-fired power plants.
Writing for the majority, in the 5-to-4 decision, Justice Antonin Scalia wrote: “It is not rational, never mind ‘appropriate,’ to impose billions of dollars in economic costs in return for a few dollars in health or environmental benefits. Statutory context supports this reading.”
In dissent, Justice Elena Kagan wrote: “The agency acted well within its authority in declining to consider costs at the opening bell of the regulatory process given that it would do so in every round thereafter — and given that the emissions limits finally issued would depend crucially on those accountings.”
“The E.P.A. will have to do more homework on costs,” said Sean Donahue, representing environmental groups. “But I’m very confident that the final rule will be up and running and finally approved without a great deal of trouble. This is a disappointment. It’s a bump in the road, but I don’t think by any means it’s the end of this program.”
