Mandatory Declassification Review [MDR] Law and Legal Definition
A Mandatory Declassification Review (MDR) is a request submitted by an individual to an agency for the review of a particular document in an attempt to declassify a document for release to the public.
When an agency receives a MDR request for the review of a particular document, the agency must respond either with an approval, a denial, or the inability to confirm or deny the existence or nonexistence of the requested document. An individual not satisfied with the agency response can file appeal. The appellate panel is known as Interagency Security Classification Appeals Panel (ISCAP).
