On April 15, the U.S. Court of Appeals for the District of Columbia Circuit granted a motion that asked the court to hold a lawsuit challenging the Environmental Protection Agency (EPA) 15 percent ethanol (E15) labeling rule in abeyance, pending action by the Supreme Court. The motion was filed on February 17 by the Alliance of Automobile Manufacturers, the Association of Global Automakers, the National Marine Manufacturers Association, and the Outdoor Power Equipment Institute; the groups originally filed the suit over the labeling rule in September 2011. The rule would require retailers to label E15 pumps. The appeals court said it would wait for the Supreme Court to respond to petitions challenging the EPA’s waivers approving use of E15 in model year 2001 and newer before addressing a challenge to the E15 pump-labeling rule.
