In a December 19, 2016 Order, the D.C. Circuit Court of Appeals delayed oral argument in the Ozone NAAQS litigation. Originally scheduled for February 16, 2017, oral argument is now scheduled for April 19, 2017. The court did not explain its reason for the delay, but some have speculated it may be to allow the new administration time to decide whether it intends to revisit the ozone standard, in which case the litigation could ultimately become moot. On the other hand, the delay may simply reflect an internal court scheduling issue. The court's Order can be accessed here.
