ous decisions of this court make clear, the district court is now required to conduct a de novo review of the classification decision, with the burden on the agency claiming the exemption. 5 U.S.C. § 552(a)(4)(B);
Salisbury v. United States, 690 F.2d 966 (D.C.1982);
Ray v. Turner, 587 F.2d 1187 (D.C.Cir.1978). In carrying out this de novo review, courts should “accord
substantial weight to an agency’s affidavit concerning the details of the classified status of the disputed record,”
6 albeit without relinquishing their independent responsibility: “While
in camera examinations need not be automatic, in many situations it will plainly be necessary and appropriate.” S.Rep. No. 1200, 93d Cong., 2d Sess. 9 (1974), U.S.Code Cong. & Admin.News 1974, pp. 6267, 6287.
Exemption 1 does not itself provide the applicable substantive standard for withholding information, but rather references standards defined by Executive Order. In this case, we turn to Exective Order 12356, 47 Fed.Reg. 14874 (1982), for national security classification standards:
1.3 Classification Standards
(a) Information shall be considered for classification if it concerns:
(2) the vulnerabilities or capabilities of systems, installations, projects, or plans relating to national security;
(3) foreign government information;
(5) foreign relations or foreign activities of the United States.
47 Fed.Reg. at 14876. We must measure the State Department’s affidavit explaining its classification of the withheld information, against these standards. Moreover, we must ensure that information not
be classified in order to conceal violations of law, inefficiency, or administrative error; to prevent embarrassment to a person, organization, or agency; to restrain competition; or to prevent or delay the release of information that does not require protection in the interest of national security.
Executive Order 12356, § 1.6(a).
While Executive Order 12356 forbids classifying documents to cover up information that is embarrassing, but not threatening to national security, it explicitly allows agencies to make classification and reclassification decisions in light of, and at the time of, FOIA requests.
(c) The President or an agency head or official designated ... may reclassify information previously declassified and disclosed if it is determined in writing that (1) the information requires protection in the interest of national security; and (2) the information may reasonably be recovered. These reclassification actions shall be reported promptly to the Director of the Information Security Oversight Office.
(d) Information may be classified or reclassified after an agency has received a request for it under the Freedom of Information Act, ... if such classification meets the requirements of this Order and is accomplished personally and on a document-by-document basis by the [designated agency person].
47 Fed.Reg. 14877-78. So long as the new classification is appropriate under the standards of § 1.3, reclassification is permitted.
B. Summary Judgment Standards
The exercise of independent, responsible, de novo review of classification decisions under Exemption 1 does not necessarily require a full trial. A motion for summary judgment under Rule 56 of the Federal Rules of Civil Procedure is still available to either party. Indeed, this court has already set out the particular standard district courts should apply to motions for summary judgment in Exemption 1 cases:
[A]n agency is entitled to summary judgment if its affidavits describe the withheld information and the justification for withholding with reasonable specificity,
