"Analysis: Obama Climate Agenda Faces Supreme Court Reckoning"
"With a barrage of legal briefs, a coalition of business groups and Republican-leaning states are taking their fight against Obama administration climate change regulations to the U.S. Supreme Court."
"The U.S. Chamber of Commerce and other industry groups, along with states such as Texas and Virginia, have filed nine petitions in recent weeks asking the justices to review four U.S. Environmental Protection Agency regulations that are designed to cut greenhouse-gas emissions.
If the court were to take up any one of the petitions, it would be the biggest environmental case since Massachusetts v. EPA, the landmark 2007 decision in which the justices ruled that carbon dioxide is a pollutant that could be regulated under the Clean Air Act."Source: Reuters, 05/17/2013
