The Protection of Classified Information: The
Legal Framework
Nathan Brooks
Legislative Attorney
American Law Division
Summary
Classification authority has generally rested with the Executive Branch, although
Congress has enacted legislation regarding the protection of certain sensitive
information. It is not clear, however, how much – if any – authority the Legislative
Branch has to constrain the Executive Branch’s power in this area. This report provides
an overview of the relationship between Executive and Legislative authority over
national security information, and summarizes the current laws and regulations that form
the legal framework protecting classified information.
Introduction. A recent incident involving access to classified information1 has
created heightened interest in the laws that govern security classification and access to
classified information, as well as the penalties for violating these laws. This report
provides an overview of the relationship between Executive and Legislative authority over
sensitive government information, and summarizes the current laws and regulations that
form the legal framework protecting such information.
Background. Prior to the New Deal, classification decisions were left to military
regulation.2 In 1940, however, President Franklin Roosevelt issued an Executive Order
authorizing government officials to protect national security.3 Since that time, presidents
have followed this precedent and set the federal government’s classification standards by
Executive Order, but with one critical difference: while President Roosevelt cited specific

Clinton. See Susan Schmidt and Dan Eggan, FBI Probes Berger for Document Removal,

statutory authority for his action, later presidents have cited general statutory and
Constitutional
authority.4
While presidents have generally grounded their authority to classify materials in
statute and in the Constitution, it is not clear how much – if any – authority the Legislative
Branch has to constrain the Executive Branch’s power in this area. The Supreme Court
has never directly addressed this issue. Citing the President’s constitutional role as
Commander-in-Chief,5 however, the Supreme Court has repeatedly stated in dicta that
“[the President’s] authority to classify and control access to information bearing on
national security...flows primarily from this Constitutional investment of power in the
President and exists quite apart from any explicit congressional grant.”6
Nevertheless, Congress has directed the President to establish procedures governing
the access to classified material so that no person can gain such access without having
undergone a background check.7 Congress also directed the President, in formulating the
classification procedures, to adhere to certain minimum standards of due process with
regard to access to classified information.8 These include the establishment of uniform
procedures for, inter alia, background checks, denial of access to classified information,
and notice of such denial.9 The statute also explicitly states that the agency heads are not
required to comply with the due process requirement where doing so could damage

McElroy
, 367 U.S. 886, 890 (1961). In addition, courts have also been wary to second-guess the
Executive Branch in areas of national security. See, e.g., Haig v. Agee, 453 U.S. 280, 291 (1981)
(“Matters intimately related to foreign policy and national security are rarely proper subjects for
judicial intervention”). There is also Supreme Court dicta to suggest a stronger – but still limited
– role for Congress in classification of information. EPA v. Mink, 410 U.S. 73, 83 (1973)
(“Congress could certainly have provided that the Executive Branch adopt new [classification
procedures] or it could have established its own procedures – subject only to whatever limitations
the Executive Privilege may be held to impose on such congressional ordering”).
7 See the Counterintelligence and Security Enhancement Act of 1994, Title VIII of P.L. 103-359
(codified at 50 U.S.C. § 435 et seq.). Congress has authorized a separate classification regime
for the protection of nuclear-related information under the Atomic Energy Act (codified at 42
U.S.C. § 2011 et seq.). In addition, the Invention Secrecy Act (codified at 35 U.S.C. § 181 et
seq.) authorizes the Commissioner of Patents to keep secret those patents on inventions in which
the government has an ownership interest and the widespread knowledge of which would, in the
opinion of the interested agency, harm national security. For a more detailed discussion of these
and other regulatory regimes for the protection of sensitive government information, see CRS

national security, although the statute directs agency heads to submit a report to the
congressional intelligence committees in such a case.10
With the authority to determine classification standards vested in the President, these
standards tend to change when a new party is swept into the White House.11 The
differences between the standards of one administration and the previous administration
have often been dramatic. As one congressionally-authorized commission put it in 1997:
The rules governing how best to protect the nation’s secrets, while still insuring that
the American public has access to information on the operations of its government,
past and present, have shifted along with the political changes in Washington. Over
the last fifty years, with the exception of the Kennedy Administration, a new
executive order on classification was issued each time one of the political parties
regained control of the Executive Branch. These have often been at variance with one
another ... at times even reversing outright the policies of the previous order.12
Various congressional committees have investigated ways to bring some continuity
to the classification system13 and to limit the President’s broad powers to shield
information from public examination.14 In 1966, Congress passed the Freedom of
Information Act (FOIA), creating a presumption that government information will be
open to the public unless it falls into one of FOIA’s exceptions. One group of excepted
information is that which under Executive Order must be kept secret for national security
or foreign policy reasons.15
10 Id. at § 435(b). The House Conference Report that accompanied this legislation in 1994
suggests that Congress understood that the line defining the boundaries of Executive and
Legislative authority in this area is blurry at best. The conferees made explicit reference to the
Egan case cited above, supra note 6 and accompanying text, expressing their desire that the
legislation not be understood to intrude on the President’s authority with regard to security
clearances. See H.R. Conf. Rep. 103-753,

15 5 U.S.C. § 552(b)(1). The Supreme Court has honored Congress’s deference to Executive
Branch determinations in this area. EPA v. Mink, 410 U.S. 73 (1973). Congress, concerned that
the Executive Branch may have declared some documents to be “national security information”
that were not vital to national security, added a requirement that such information be “properly
classified pursuant to an executive order.” 5 U.S.C. § 552(b)(1)(B). This only means, however,
that the Executive Branch must comply with its own regulations. Without a statutory standard
for determining what is proper, however, courts have been left with the aforementioned Executive
Order-based standards. See CRS Report RL31245, Protection of National Security Information:

Executive Order 12,958 (as amended). The present standards for classifying
and declassifying information were last amended in March, 2003.16 Under these current
standards, the President, Vice President, agency heads, and any other officials so
designated by the President may classify information upon a determination that the
unauthorized disclosure of such information could reasonably be expected to damage
national security.17 Such information must be owned by, produced by, or under the
control of the federal government, and must concern one of the following:
! military plans, weapons systems, or operations;
! foreign government information;
! intelligence activities, intelligence sources/methods, cryptology;
! foreign relations/activities of the United States;
! scientific, technological, or economic matters relating to national
security;
! federal programs for safeguarding nuclear materials or facilities;
! vulnerabilities or capabilities of national security systems; or
! weapons of mass destruction.18
Information is classified at one of three levels based on the amount of danger that its
unauthorized disclosure could reasonably be expected to cause to national security.19
Information is classified as “Top Secret” if its unauthorized disclosure could reasonably
be expected to cause “exceptionally grave damage” to national security. The standard for
“Secret” information is set at “serious damage” to national security, while for
“confidential” information the standard is “damage” to national security. Significantly,
for each level, the original classifying officer must identify or describe the specific danger
potentially presented by the information’s disclosure.20 The officer who originally
classifies the information must attempt to establish a date for declassification based upon
the expected duration of the information’s sensitivity. If the office cannot set an earlier
declassification date, then the information must be marked for declassification in ten
years’ time or twenty-five years, depending on the sensitivity.21 The duration of

classification can be extended if the threat to national security possessed by the
information still exists.22
Classified information is required to be declassified “as soon as it no longer meets
the standards for classification,”23 although there is a presumption that classified
information continues to meet these standards. The original classifying agency has the
authority to declassify information when the public interest in disclosure outweighs the
need to protect that information.24 On December 31, 2006, and every year thereafter, all
information that has been classified for 25 years or longer and has been determined to
have “permanent historical value” under Title 44 of the U.S. Code will be automatically
declassified, although agency heads can exempt from this requirement classified
information that continues to be sensitive in a variety of specific areas.25
Agencies are required to review classification determinations upon a request for such
a review that specifically identifies the materials so that the agency can locate them.26
This requirement does not apply to information that has undergone declassification review
in the previous two years, information that is exempted from review under the National
Security Act,27 or information classified by the incumbent President and staff, the Vice
President and staff (in the performance of executive duties), commissions appointed by
the President, or other entities within the Executive Office of the President that advise the
President.28 Each agency that has classified information is required to establish a system
for periodic declassification reviews.29 The National Archivist is required to establish a
similar systemic review of classified information that has been transferred to the National
Archives.30
Access to classified information is generally limited to those who demonstrate their
eligibility to the relevant agency head, sign a nondisclosure agreement, and have a need
to know the information.31 The need-to-know requirement can be waived, however, for
former Presidents and Vice Presidents, historical researchers, and former policy-making
officials who were appointed by the President or Vice President.32 The information being
accessed may not be removed from the controlling agency’s premises without permission.

Each agency is required to establish systems for controlling the distribution of classified
information.33
The Information Security Oversight Office (ISOO) - an office within the National
Archives - is charged with overseeing compliance with the classification standards and
promulgating directives to that end.34 ISOO is headed by a Director, who is appointed by
the Archivist of the United States, and who has the authority to order declassification of
information that, in the Director’s view, is classified in violation of the aforementioned
classification standards.35 In addition, there is an Interagency Security Classifications
Appeals Panel (“the Panel”), headed by the ISOO Director and made up of representatives
of the heads of various agencies, including the Departments of Defense, Justice, and State,
as well as the Central Intelligence Agency, and the National Archives.36 The Panel is
empowered to decide appeals of classifications challenges37 and to review automatic and
mandatory declassifications. If the ISOO Director finds a violation of Executive Order
12,958 (as amended) or its implementing directives, then the Director must notify the
appropriate classifying agency so that corrective steps can be taken. Officers and
employees of the United States (including contractors, licensees, etc.) who commit a
violation are subject to sanctions that can range from reprimand to termination.38
Criminal Penalties. Generally, federal law prescribes a prison sentence of no
more than a year and/or a $1,000 fine for officers and employees of the federal
government who knowingly remove classified material without the authority to do so and
with the intention of keeping that material at an unauthorized location.39 Stiffer penalties
– fines of up to $10,000 and imprisonment for up to ten years – attach when a federal
employee transmits classified information to anyone that employee has reason to believe
is an agent of a foreign government.40 Fines and a ten-year prison terms also await
anyone, government employee or not, who publishes, makes available to an unauthorized
person, or otherwise uses to the United States’ detriment classified information regarding
the codes, cryptography, and communications intelligence utilized by the United States
or a foreign government.41

of “national defense” information, prescribing fines and a prison term of up to ten years.
