Interagency Security Classification Appeals Panel (ISCAP)

The Interagency Security Classification Appeals Panel (ISCAP) provides one of the necessary checks and balances to the President's classification program outlined in Executive Order 12958, as amended, "Classified National Security Information" (PDF Format).

Additionally, the ISCAP helps provide Federal employees with assistance in classification and declassification decisions through its function of deciding on exemptions from automatic declassification submitted by agency heads.

Lastly, the ISCAP provides a venue for the public to present appeals concerning requests for declassification of classified information through the Mandatory Declassification Review (MDR) process. All information classified under the provisions of the Order, with limited exception, can be subject to a request for MDR. The Order therefore requires all agency heads to establish procedures for handling such requests. As the highest appellate body for declassification decisions, the ISCAP may decide on MDR requests denied at the agency level.
