Foreign Intelligence Surveillance Court (FISA Court / FISC)

Executive Profile (BLUF)

The Foreign Intelligence Surveillance Court (FISC, commonly “FISA Court”) is a specialized US federal court established by the Foreign Intelligence Surveillance Act (FISA) of 1978 to oversee requests for surveillance warrants against foreign spies and terrorists inside the United States. The court — comprising 11 Article III federal judges appointed by the Chief Justice of the Supreme Court to rotating seven-year terms — reviews applications submitted by the Department of Justice (on behalf of the FBI and other IC agencies) for electronic surveillance, physical searches, pen registers, and business records collection under the FISA framework. The FISA Court operates in secret (classified proceedings, classified opinions) and has historically approved the vast majority of applications — generating long-running civil liberties criticism about its role as a “rubber stamp.” Post-Snowden reforms (USA FREEDOM Act, 2015) introduced an amicus curiae mechanism for adversarial argument on significant legal questions. Section 702 reauthorization debates (collection of foreign targets’ communications that incidentally captures US persons) are the court’s most politically salient recurring controversy.
