In an unprecedented move, the Supreme Court issued an order yesterday staying the Clean Power Plan, which is widely regarded as the centerpiece of the Obama Administration’s effort to address climate change.

If the case goes to the Supreme Court, it would not issue its final decision until well after the next President takes office.
