(a) Authorized holders of information classified by DHS or any other agency who, in good faith, believe that specific information is improperly or unnecessarily classified are encouraged and expected to challenge the classification status of that information pursuant to section 1.8 of Executive Order 13526. Authorized holders may submit classification challenges in writing to the original classification authority with jurisdiction over the information in question.
