EPIC has filed a brief in response to an appeal by the Department of Justice in EPIC v. DHS, concerning the government policy to disrupt cellular networks. EPIC won a major FOIA victory when a federal district court ruled that the DHS could not withhold "SOP 303," a government procedure to shut down cellular phone service. EPIC sought the policy after authorities shut down cell phone service at a peaceful protest in San Francisco. The government argued it did not need to release the document to EPIC because it was a "law enforcement technique" and because it would endanger the physical safety of an individual. The federal court rejected those arguments and ordered that the document be disclosed to EPIC, pending a decision on the appeal. For more details, see EPIC v. DHS—SOP 303.
