How is a mandatory declassification review request different from a FOIA request for classified records?

A mandatory declassification review (MDR) request and a Freedom of Information Act (FOIA) request can both be used to seek classified federal records, and they sometimes return similar results. But they run on different legal authorities, follow different review processes, and offer different appeal routes. Understanding the distinction helps a requester choose the path most likely to succeed.

Different legal foundations

MDR is a creature of the classification system itself. It is established by executive order governing national security information and exists specifically to let any person ask an agency to review a particular classified record and release whatever no longer needs protection.

FOIA is a statute giving the public a right of access to agency records generally. Classified material is just one category FOIA touches, and it is protected under a specific national-security exemption.

What each one covers

• MDR is narrow and targeted. It applies only to classified information and requires the requester to describe a specific record with enough detail that the agency can locate it with reasonable effort.
• FOIA is broad. It reaches almost any agency record regardless of subject, and it accommodates wide-ranging or topic-based requests.

Different review and appeal tracks

Under MDR, the agency reviews the record against current classification standards and releases everything that no longer qualifies for protection, referring information to other agencies that hold an interest (an equity). If the requester is dissatisfied, MDR offers appeal rights that ultimately reach the Interagency Security Classification Appeals Panel (ISCAP) — an independent body that can overrule an agency’s decision to keep information classified.

Under FOIA, the agency weighs the record against FOIA’s exemptions, including the one for properly classified national-security information. FOIA has its own administrative appeal process and the option of judicial review in federal court.

Choosing a path

Many researchers file MDR for a focused review of specific documents, valuing the ISCAP route. Others use FOIA for broader subject searches or to combine national-security records with other material. The two are not mutually exclusive, and the same record may be requested either way — though an agency generally will not process both simultaneously for the same documents.
