SEATTLE - A majority of the nonrecused judges in the Ninth Circuit U.S. Court of Appeals on Feb. 3 denied a fellow judge's request for an en banc hearing of a ruling finding that environmental groups had standing to bring to lawsuit claiming that state agencies in Washington violated the Clean Air Act (CAA) by failing to define reasonably available control technology (RACT) emissions limits for greenhouse gases (Washington Environmental Council, et al. v. Maia D. Bellon, et al., Nos. 12-35323, 12-35234, 12-35358, 9th Cir.; 2014 U.S. App. LEXIS 2065).
