On April 11, 2014, the American Petroleum Institute (API) and American Fuel & Petrochemical Manufacturers (AFPM) petitioned the U.S. Court of Appeals for the District of Columbia Circuit to place a hold on their challenge to EPA's 2013 RFS final rule until EPA completes its reconsideration of the rule. EPA joined in the motion.

Just days earlier, on Monday, April 7, 2014, the parties to the litigation challenging EPA's 2013 final RFS rule, including API, AFPM, and EPA, were in court arguing the merits of the case. The Biobased and Renewable Products Advocacy Group's (BRAG™) coverage of these oral arguments is available online.
