The Archivist of the United States shall have authority to review and declassify information and material which has been classified by a President, his White House Staff or special committee or commission appointed by him and which the Archivist has in his custody at any archival depository, including a Presidential library. Such declassification shall only be undertaken in accord with:

(ii) Consultations with the Departments having a primary subject-matter interest; and
(iii) The provisions of § 11.5(c).
