In an events-filled blogging day, here’s another important development. The D.C. Circuit denied motions by numerous state and private party petitioners to stay the Clean Power Plan pending resolution of the legal challenges. At the same time, the court granted motions for expedited briefing of those challenges and set June 2, 2016, as the date for oral argument. Many, many lawyers will be burning the midnight oil in the District of Columbia and the hinterlands in efforts to get their briefs filed on time and within the word count limits. In the meantime, some petitioners have already issued press releases stating that they will appeal the D.C. Circuit’s ruling to the U.S. Supreme Court.
