who determines the composition of the foreign intelligence surveillance court (fisc)
United States Foreign Intelligence Surveillance Court Each application for one of these surveillance warrants (called a FISA warrant) is made before an individual judge of the court. The court may allow third parties to submit briefs as amici curiae. When the U.S. Attorney General determines that an emergency exists, the Attorney General may authorize the emergency employment of electronic surveillance before obtaining the necessary authorization from the FISC, if the Attorney General or their designee notifies a judge of the court at the time of authorization and applies for a warrant as soon as practicable but not more than seven days after authorization of such surveillance, as required by 50 U.S.C. § 1805.
