This is coming from a few different sources none of which are really linkable so I'll just copy and paste this press release from the Environmental Defense Fund:
*** BREAKING *** BREAKING *** BREAKING ***
Moments ago, a federal appeals court upheld EPA's climate pollution emission standards, rejecting four legal challenges that had been filed by industry groups and several states' attorneys general.
The court ruled in favor of clean air protections in four major cases, denying petitions against the Climate Pollution Endangerment Finding and the Clean Car Standards and dismissing petitions against the Timing and Tailoring Rules.
EDF activists submitted tens of thousands of comments in favor of these critical rules and today's court decision affirms our efforts to defend EPA's common sense solutions to promote cleaner air and a safer climate future.
This ruling also comes one day after the public comment period closed on the proposed new EPA rule that would limit climate pollution from new fossil fuel power plants. An incredible 113,579 EDF activists joined a record-shattering 2 million Americans who submitted comments in favor of this rule that, if implemented, will help end dirty energy as we know it.
Science Magazine had a nice piece on the decision (http://news.sciencemag.org/scienceinsider/2012/06/climate-science-gets-…) with an excellent sound-bite from the appeals court's decision:
"EPA is not required to re-prove the existence of the atom every time it approaches a scientific question."
As described in the Science news piece, the court came down quite firmly on the side of both the ACG science itself, and on EPA's use of it in formulating its regulations.
