22 C.F.R. § 9.9 Duration of classification.
Title 22 - Foreign Relations
(a) Information shall be classified for as long as is required by national security considerations. When it can be determined, a specific date or event for declassification shall be set by the original classification authority at the time the information is originally classified. (b) Information classified under predecessor orders that is not subject to automatic declassification or that is marked for review before declassification shall remain classified until reviewed for declassification. (c) Automatic declassification determinations under predecessor orders shall remain valid unless the classification is extended by an authorized official of the originating agency. These extensions may be by individual documents or categories of information. The agency shall be responsible for notifying holders of the information of such extensions as soon as possible. The authority to extend the classification of information subject to automatic declassification under predecessor orders is limited to those officials who have classification authority over the information and are designated in writing to have original classification authority at the level of the information to remain classified. Any decision to extend this classification on other than a document-by-document basis shall be reported to the Director of the ISOO.
