THIS IS VERY BIG BREAKING NEWS: The Supreme Court has stayed the Obama Administration’s vastly overreaching Clean Power Plan:

The surprising move on Tuesday is a blow to the administration and a victory for the coalition of 27 mostly Republican-led states and industry opponents that call the regulations “an unprecedented power grab.”

By temporarily freezing the rule the high court’s order signals that opponents have made a strong argument against the plan. A federal appeals court last month refused to put it on hold.

The plan aims to stave off the worst predicted impacts of climate change by reducing carbon dioxide emissions at existing power plants by about one-third by 2030.

Appellate arguments are set to begin June 2.

The decision to stay the regulation was along ideological lines, 5-4.
