What are the steps to file a mandatory declassification review request with a federal agency?

Mandatory declassification review (MDR) is a process that lets the public ask a federal agency to review specific classified records and release them if they no longer require protection. It is established under the executive order governing classified national security information and is administered with oversight from the Information Security Oversight Office. MDR is separate from the Freedom of Information Act, though the same records can sometimes be requested under either path.

Before you file

• Identify the right agency. Send your request to the agency that has custody of the records or originated them. For older records that have been transferred to the National Archives, the National Archives may handle or coordinate the review.
• Describe the records specifically. Agencies generally require that you identify the document with enough detail that it can be located with a reasonable amount of effort. Vague or overly broad requests are often returned.

Steps to file

1. Put the request in writing. Address it to the agency’s MDR or records office and state clearly that you are seeking a mandatory declassification review.
2. Identify the records. Provide titles, dates, originators, subject matter, or any reference numbers you have.
3. Include your contact information and any handling preferences for the response.
4. Submit through the agency’s designated channel, which may be mail, email, or an online portal. Check the agency’s website for current instructions.

After you submit

• The agency reviews the records and decides whether information can be declassified in whole, in part, or remains classified.
• Some information may be withheld even after review if another law or exemption protects it.
• If material is denied, you typically have the right to appeal within the agency. If the agency denial is upheld, you may be able to appeal to the Interagency Security Classification Appeals Panel, the body that resolves such challenges.

Practical tips

Keep copies of everything you send, note the date you filed, and follow up if you do not receive an acknowledgment. Processing can take time, especially for older or widely dispersed records.
