Legal order prohibiting parties from publicly discussing a case or government demand
A gag order is a legal directive that prohibits individuals or organizations from publicly discussing specific information, legal proceedings, or government demands. In the national security context, gag orders are routinely attached to National Security Letters (NSLs), FISA Court orders, and other surveillance demands, preventing recipients from disclosing that they have received such orders or providing any details about what was requested.
The combination of surveillance authority and mandatory secrecy creates a system of invisible coercion. A technology company that receives an NSL demanding customer data is legally prohibited from telling the affected customer, disclosing the demand in public reports, or even acknowledging that the demand exists. The gag order transforms a legal instrument into a mechanism of secrecy that shields government activity from any form of public accountability.
Legal challenges to gag orders have produced mixed results. In 2015, a federal court ruled that the FBI's use of perpetual gag orders on NSLs was unconstitutional. Technology companies including Apple, Google, and Microsoft have fought for the right to publish aggregate statistics about government demands. The tension between government secrecy and public accountability remains unresolved, with gag orders serving as a primary tool for keeping surveillance activities invisible.
