Tthe Supreme Court has ruled against the EPA's effort to limit power plant emissions.

FOX News Radio's Jon Decker has more from the White House:

The EPA rules curbing emissions of mercury and other hazardous air pollutants took effect in April. But in a 5-4 decision, the High Court said the Obama Administration should have considered costs when it issued the regulations to limit emissions of hazardous pollutants mainly from coal-fired power plants.

In a statement, the EPA said it is disappointed that the Court did not uphold the rules and the agency is now determining any appropriate next steps. The case now goes back to lower courts for the EPA to decide how to account for costs.

The challenge to the EPA rules was brought 21 Republican-led states.
