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

The procedural protections of CIPA protect unnecessary disclosure of classified information.

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, 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. 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.

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