On August 29, 2011, a coalition of nine public interest groups led by Public Knowledge filed an Emergency Petition asking the U.S. Federal Communications Commission (FCC) to declare "that the actions taken by the Bay Area Rapid Transit District (“BART”) on August 11, 2011 violated the Communications Act of 1934, as amended, when it deliberately interfered with access to Commercial Mobile Radio Service (“CMRS”) by the public" and "that local law enforcement has no authority to suspend or deny CMRS, or to order CMRS providers to suspend or deny service, absent a properly obtained order from the Commission, a state commission of appropriate jurisdiction, or a court of law with appropriate jurisdiction".
