The U.S. Supreme Court has agreed to hear the legal challenge to the South Coast Air Quality Management District’s (SCAQMD) regulations which would place new restrictions on the types of vehicles government agencies and some private fleets may acquire in Southern California. The National Association of Fleet Administrators (NAFA) and the American Automotive Leasing Association (AALA) are planning to file a joint “friend of the court” brief with the U.S. Supreme Court in an attempt to stop the SCAQMD’s plans to mandate certain fleet vehicle acquisitions. The brief will argue that the SCAQMD rules, which are neither a part of the Clean Air Act’s mandates nor a substitute, are preempted because they are in an area Congress has designated for federal control.
