During calendar year 2002, 1228 applications were made to the Foreign Intelligence Surveillance Court for electronic surveillance and physical search. The Court initially approved 1226 applications in 2002. Two applications were "approved as modified," and the United States appealed these applications to the Foreign Intelligence Surveillance Court of Review, as applications having been denied in part. On November 18, 2002, the Court of Review issued a judgment that "ordered and adjudged that the motions for review be granted, the challenged portions of the orders on review be reversed, the Foreign Intelligence Surveillance Court's Rule 11 be vacated, and the cases be remanded with instructions to grant the United States' applications as submitted..." Accordingly, all 1228 applications presented to the Foreign Intelligene Surveillance Court in 2002 were approved.
