Applicable Presidential Executive Orders[edit]


The primary purpose of CIPA was to limit the practice of graymail by criminal defendants in possession of sensitive government secrets. "Gray mail" refers to the threat by a criminal defendant to disclose classified information during the course of a trial. The gray mailing defendant essentially presented the government with a "dilemma": either allowed disclosure of the classified information or dismiss the indictment.

The procedural protections of CIPA protect unnecessary disclosure of classified information.[2][3]

CIPA was not intended to infringe on a defendant's right to a fair trial or to change the existing rules of evidence in criminal procedure,[4] and largely codified the power of district courts to come to pragmatic accommodations of the government's secrecy interests with the traditional right of public access to criminal proceedings.[citation needed] Courts therefore did not radically alter their practices with the passage of CIPA; instead, the Act simply made it clear that the measures courts already were taking under their inherent case-management powers were permissible.[citation needed]

CIPA, by its terms, covers only criminal cases. CIPA only applies when classified information is involved, as defined in the Act's Section 1.
