United States Edit
Executive Order 13526 establishes the mechanisms for most declassifications, within the laws passed by Congress. The originating agency assigns a declassification date, by default 10 years. After 25 years declassification review is automatic, with nine narrow exceptions that allow information to continue to be classified. At 50 years there are two exceptions, and classifications beyond 75 years require special permission. Because of changes in policy and circumstances, agencies are expected to actively review documents that have been classified for fewer than 25 years. They must also respond to Mandatory Declassification Review and Freedom of Information Act requests.
The National Archives and Records Administration houses the National Declassification Center to coordinate reviews and the Information Security Oversight Office to promulgate rules and enforce quality measures across all agencies. NARA reviews documents on behalf of defunct agencies and permanently stores declassified documents for public inspection. The Interagency Security Classification Appeals Panel has representatives from several agencies.
"There are four declassification programs within the executive branch: automatic declassification, systematic declassification review, discretionary declassification review, and mandatory declassification review."
