The Foreign Intelligence Surveillance Act (FISA) is a U.S. law enacted in 1978 that establishes procedures for the surveillance and collection of foreign intelligence information. FISA allows federal authorities to conduct electronic surveillance and physical searches without a traditional warrant, provided they follow specific guidelines to ensure that the targets are foreign powers or agents of foreign powers. This act plays a crucial role in the intersection of national security and civil liberties, balancing the need for security with protections against unlawful government surveillance.
