EPIC has filed a petition to the U.S. Supreme Court in a long-running battle to obtain a secret government cellphone shutdown policy. EPIC has pursued the Department of Homeland Security policy since BART officials shut down cell phone service during a peaceful protest in 2011.. The demonstrators were protesting the police's killing of an unarmed homeless man. The appellate court's decision, wrote EPIC, "is contrary to the intent of Congress, this Court's precedent, and this Court's specific guidance on statutory interpretation." A federal judge previously ruled in EPIC's favor.
