The Freedom of Information Act and Nondisclosure Provisions in Other Federal Laws  
 
Summary 
Congress continues to consider how to balance the federal government’s growing need for 
sensitive or confidential business information, the public’s right of access to information about 
government activities, and the private sector’s interest in keeping its sensitive or proprietary 
information protected from public disclosure. In enacting the Freedom of Information Act 
(FOIA), 5 U.S.C. § 552, Congress sought to balance the right of the public to know and the need 
of the government to protect certain information. FOIA’s broad provisions favoring disclosure, 
coupled with the specific exemptions, represent the balance Congress achieved. The federal FOIA 
is an information access statute enacted in 1966 that applies to agency records of the executive 
branch of the federal government. FOIA requires that certain types of records be published in the 
Federal Register, that certain types of records be made available for public inspection and 
copying, and that all other records be subject to request in writing. All records not available via 
publication or inspection, not exempt from disclosure, or excluded from coverage are subject to 
disclosure. Disputes over access to requested records may be reviewed in federal court where the 
burden is on the agency to sustain its action. 
Exemption 3 of FOIA provides that in order for a federal law other than FOIA to qualify as a 
withholding statute, it must require that information be withheld or permit information to be 
withheld by particular statutory criteria or permit information to be withheld based upon a 
statutory reference to particular types of information and must specifically cite to Exemption 3. 
Courts have taken different approaches over whether the withholding criteria in nondisclosure 
statutes should be construed narrowly, consistent with FOIA’s strong preference for disclosure, or 
broadly, consistent with the deferential standards of administrative law. 
Congress has enacted legislative exemptions from FOIA to provide assurance that private 
information submitted to government agencies will not be disclosed or will only be disclosed in 
limited situations. Generally, the legislation has exempted covered information from disclosure 
under FOIA. Congress has recognized that some situations do not fall within FOIA’s framework. 
The proliferation of legislative exemptions from FOIA has resulted in widespread concern that 
information that needs to be shared will be inappropriately withheld. To respond to these 
concerns, Congress enacted the OPEN FOIA Act of 2009, P.L. 111-83, which requires that when 
Congress provides for a statutory exemption to FOIA, Congress must state its intention clearly. 
During the 111th Congress, two legislative exemptions from FOIA have been particularly 
controversial. The first, The Protected National Security Documents Act of 2009, Section 565 of 
P.L. 111-83, was enacted in response to litigation under FOIA to obtain photographs depicting the 
alleged mistreatment of detainees in Iraq and Afghanistan. The second, a provision in the Dodd-
Frank Wall Street Reform and Consumer Protection Act, Section 929I of P.L. 111-203, grants an 
exemption from FOIA to the Securities and Exchange Commission for certain information 
received from entities it regulates, or information used for other regulatory and oversight 
activities. Chairman Frank of the House Financial Services Committee has scheduled a hearing 
on September 16, 2010, to consider the Dodd-Frank FOIA exemption and to explore concerns 
raised about the provision. 
This report will examine these issues and will be updated as warranted.

The Freedom of Information Act 
The leading treatise on federal information disclosure notes that “[t]he protection of private data 
submitted to a federal agency has long been a source of considerable controversy.”1 
The expanding range of federal regulatory activity and growth in the Government sector of 
the economy have increased federal agencies’ demand for information about the activities of 
private individuals and corporations. These developments have paralleled a related concern 
about secrecy in Government and abuse of power. The Freedom of Information Act ... was a 
response to this concern, but it has also had a largely unforeseen tendency to exacerbate the 
uneasiness of those who comply with government demands for information. For under the 
FOIA third parties have been able to obtain Government files containing information 
submitted by corporations and individuals who thought the information would be held in 
confidence.2 
The federal Freedom of Information Act (FOIA) is an information access statute enacted in 1966 
that applies to agency records of the executive branch of the federal government.3 FOIA requires 
that certain types of records be published in the Federal Register,4 that certain types of records be 
made available for public inspection and copying,5 and that all other records be subject to request 
in writing. All records not available via publication or inspection, not exempt from disclosure, or 
excluded from coverage are subject to disclosure.6 Disputes over access to requested records may 
be reviewed in federal court where the burden is on the agency to sustain its action.7 
FOIA establishes a federal statutory right of access for “any person”8 to records of agencies and 
departments of the executive branch of the U.S. government unless the requested record is 
specifically exempted from disclosure under one or more of the act’s nine exemptions9 or 
specifically excluded coverage under one of three exclusions for especially sensitive law 
enforcement matters. Agency records sought are not necessarily disclosed because FOIA has nine 
exemptions from disclosure for national security, law enforcement, other federal withholding

statutes, confidential business information, personal privacy, and other circumstances.10 The 
exemptions permit, rather than require, the withholding of the requested information.11 The 
Obama Administration has adopted a presumption in favor of disclosure in FOIA decisions.12 The 
FOIA guidelines issued by Attorney General Holder counsel that an agency should not withhold 
information simply because it may do so legally; and that whenever an agency determines that it 
cannot make full disclosure of a requested record, it must consider whether it can make partial 
disclosure.13 “[T]he Department of Justice will defend a denial of a FOIA request only if (1) the 
agency reasonably foresees that disclosure would harm an interest protected by one of the 
statutory exemptions, or (2) disclosure is prohibited by law.”14 
Exemption 3—Information Exempt by Statute 
As originally enacted in 1966, Exemption 3 exempted from mandatory disclosure matters that 
were “specifically exempted from disclosure by statute.”15 Basically there were two types of 
statutes covered by the exemption: mandatory withholding and discretionary withholding statutes. 
Agency regulations established how to determine which information could be disclosed when 
discretionary withholding statutes were involved. 
Exemption 3 was amended in 1976 to overturn the Supreme Court’s 1975 decision in 
Administrator, Federal Aviation Administration v. Robertson.16 In Robertson, the Court held that a 
section of the Federal Aviation Act concerning public disclosure of agency reports satisfied the 
requirements of the former Exemption 3 even if the statute gave an agency broad discretion to 
determine whether the information should be withheld. Exemption 3 was rewritten to provide that 
information may be withheld under an Exemption 3 statute when that statute either “(A) requires 
that matters be withheld from the public in such a manner as to leave no discretion on the issue, 
                                                
10 According to the Department of Justice the total number of FOIA requests received by all federal departments and 
agencies during FY2009 was 557,825. The total number of FOIA requests processed during FY2009 was 612,893. 
Approximately 60% of these requests resulted in the release of either all or some of the requested records. 
Approximately 407,650 requests were processed for exemption applicability and records were either released in full or 
in part, or denied in full based on FOIA’s exemptions. Of that 407,650, more than half resulted in full releases of 
information, and approximately 94% resulted in release of either some or all of the requested information. Fifty-six 
percent of grants were full grants of all the requested information. The full denials based on exemptions constituted just 
over 6% of these requests. U.S. Department of Justice, Summary of Annual FOIA Reports for Fiscal Year 2009,

Attorney General Holder rescinded Attorney General Ashcroft’s FOIA Memorandum of October 12, 2001, which 
stated that the Department of Justice would defend decisions to withhold records “unless they lack a sound legal basis 
or present an unwarranted risk of adverse impact on the ability of other agencies to protect other important records.”

or (B) establishes particular criteria for withholding or refers to particular types of matters to be 
withheld.”17 
To withhold a document under Exemption 3, the agency bears the burden of demonstrating that 
the statute either requires that the document or documents be withheld without agency 
discretion18 or specifically authorizes the agency to use discretion to withhold that type of 
document.19 If the information to be withheld falls within the scope and coverage of the federal 
statute relied upon, the information is properly exempt from disclosure under Exemption 3 of 
FOIA. The scope of the statute must be examined by a reviewing court to determine whether it 
qualifies as a withholding statute. 
[A] statute that is claimed to qualify as an Exemption 3 withholding statute must, on its face, 
exempt matters from disclosure. [The court] must find a congressional purpose to exempt 
matters from disclosure in the actual words of the statute (or at least in the legislative history 
of FOIA)—not in the legislative history of the claimed withholding statute, nor in an 
agency’s interpretation of the statute.20 
Basic principles of statutory construction are to be used to determine Exemption 3 status.21 When 
resolving an ambiguity about the proper interpretation of a specific statute under Exemption 3, 
the Chevron22 rule of judicial deference applies to the agency’s interpretation of the statute it 
administers.23 Substantial weight is to be given to an agency’s claim of Exemption 3 status. 
The first subpart of Exemption 3 is often referred to as the “no discretionary release” category. To 
satisfy this requirement, the statute’s language to withhold must be absolute—for example, stating 
that the information “shall not be disclosed.” To withhold a document, the agency must show that 
the document is collected or generated under the agency’s statutory authority, and that the statute 
contained a mandate that this type of information not be disclosed. For example, the Supreme 
Court found no discretion within the Census Act’s prohibition against disclosure of census 
records.24 
The second subpart of Exemption 3, commonly referred to as the “particular criteria” category, 
permits agency discretion on whether to withhold or disclose agency records. An agency has the 
discretion to disclose if it so chooses but also has authority to withhold. The statute must establish 
particular criteria for withholding or refer to particular types of matters to be withheld. The statute 
must provide articulable criteria for the agency to use to determine whether to permit disclosure. 
The Supreme Court looks for “sufficiently definite standards” in a statute rather than “broad

discretion.”25 The statute must be “the product of congressional appreciation of the dangers 
inherent in airing particular data and must incorporate a formula whereby the administrator may 
determine precisely whether the disclosure in any instance would pose the hazard that Congress 
foresaw.”26 
In 2009, Congress passed another substantive amendment to Exemption 3 of FOIA entitled the 
“OPEN FOIA Act of 2009.”27 The OPEN FOIA Act requires that when Congress provides for a 
statutory exemption to FOIA, Congress must state its intention to do so explicitly and clearly.28 
The OPEN FOIA Act requires that any statute “enacted after the date of enactment of the OPEN 
FOIA Act of 2009” must “specifically cite to this paragraph [5 U.S.C. § 552(b)(3)].”29 Congress 
enacted the OPEN FOIA Act of 2009 to address what has been referred to as “exemption creep.” 
Senate Judiciary Chairman Patrick Leahy, co-sponsor of the OPEN FOIA Act, remarked that 
While no one can fairly question the need to keep certain Government information secret to 
ensure the public good, excessive Government secrecy is a constant temptation and the 
enemy of a vibrant democracy.... The FOIA exemption commonly known as the “(b)(3) 
exemption,” requires that Government records that are specifically exempted from FOIA by 
statute be withheld from the public. In recent years, we have witnessed an alarming number 
of FOIA (b)(3) exemptions being offered in legislation—often in very ambiguous terms—to 
the detriment of the American public’s right to know.... The bedrock principles of open 
Government lead me to believe that (b)(3) statutory exemptions should be clear and 
unambiguous, and vigorously debated before they are enacted into law. Too often, legislative 
exemptions to FOIA are buried within a few lines of very complex and lengthy bills, and 
these new exemptions are never debated openly before becoming law. The consequence of 
this troubling practice is the erosion of the public’s right to know, and the shirking of 
Congress’ duty to fully consider these exemptions. The OPEN FOIA Act will help stop this 
practice and shine more light on the process of creating legislative exemptions to FOIA. That 
will be the best antidote to the “exemption creep” that we have witnessed in recent years.30 
As amended in 2009, Exemption 3 provides, 
(3) specifically exempted from disclosure by statute (other than section 552b of this title), if 
that statute - (A)(i) requires that the matters be withheld from the public in such a manner as 
to leave no discretion on the issue; or (ii) establishes particular criteria for withholding or

28 A potential interpretive question may arise, should Congress enact a statute intending to exempt information from 
disclosure but omitting the required reference to paragraph (b)(3) of FOIA. The legal principal at issue is that one 
Congress cannot bind a future Congress. See, e.g., Cooper v. Gen. Dynamics, 533 F.2d 163, 169 (5th Cir.1976) (holding 
that one Congress cannot insulate a statute from amendments by future Congresses). As applied to the OPEN FOIA 
Act, the question for a reviewing court could be whether the absence of the required reference to FOIA paragraph 
(b)(3) prevents the intended exemption from being effective. 
29 The OPEN FOIA Act was based on language proposed by the Senate in conference. The conference language 
mirrors legislation that the Senate Judiciary Committee favorably reported and the Senate unanimously passed during 
the 109th Congress, S. 1181.

refers to particular types of matters to be withheld; and (B) if enacted after the date of 
enactment of the OPEN FOIA Act of 2009, specifically cites to this paragraph.31 
The agency is required to determine whether the information to be withheld falls within the scope 
of the nondisclosure statute. Unlike other FOIA exemptions, if the information requested under 
FOIA meets the withholding criteria of Exemption 3, the information must be withheld. 
Courts have taken different approaches over whether the withholding criteria in nondisclosure 
statutes should be construed narrowly,32 consistent with FOIA’s strong preference for disclosure, 
or broadly, consistent with the deferential standards of administrative law.33 Numerous statutes 
have been held by courts to qualify as Exemption 3 statutes.34 In addition, agencies often rely on 
statutes as a basis for Exemption 3 withholding without a court having determined whether the 
nondisclosure statute qualifies as an Exemption 3 withholding statute. 
Legislative Exemptions from FOIA 
Corporations and federal agencies have sought legislative exemptions from FOIA for certain 
categories of information. Legislative exemptions from FOIA are often referred to as 
nondisclosure statutes. Private industry has argued that FOIA’s exemptions do not provide the 
certainty of protection needed to assure them that confidential business information voluntarily 
provided to the government will not be released under FOIA. Agencies have sought or justified 
                                                
31 5 U.S.C. § 552(b)(3). 
32 Anderson v. HHS, 907 F.2d 936, 951 (10th Cir. 1990)(taking into account well-established rules that the FOIA is to 
be broadly construed in favor of disclosure and its exemptions are to be narrowly construed” in determining how to 
interpret Exemption 3 statute). 
33 See Church of Scientology Int’l v. DOJ, 30 F.3d 224, 235 (1st Cir. 1994) (finding that, unlike actions under other 
FOIA exemptions, agency decisions to withhold materials under Exemption 3 are entitled to some deference.”); 
Aronson v. IRS, 973 F.2d 962, 967 (1st Cir. 1992)(“once a court determines that the statute in question is an Exemption 
3 statute, FOIA de novo review normally ends” and “[a]ny further review must take place under more deferential, 
administrative law standards”). 
34 The following list includes statutes that courts have found to qualify as Exemption 3 statutes. The Commodity 
Exchange Act authorizes the withholding of “[D]ata and information that would separately disclose the business 
transactions of any person” and trade secrets or names of customers gathered in the course of the Commission’s 
investigations under the Commodity Exchange Act. 7 U.S.C. § 12. The Federal Trade Commission Act authorizes the 
withholding of “[A]ny trade secret or any commercial or financial information which is obtained from any person and 
which is privileged or confidential” and certain investigative materials received by the FTC and “provided pursuant to 
any compulsory process under this subchapter or which is provided voluntarily in place of such compulsory process.” 
15 U.S.C. §§ 46(f), 57b-2. The Antitrust Civil Process Act authorizes withholding of “Any documentary material, 
answers to written interrogatories, or transcripts of oral testimony” provided pursuant to certain civil investigative 
demands pertaining to antitrust investigations.” 15 U.S.C. § 1314(g). The Consumer Product Safety Act authorizes 
withholding of certain information reported to, or otherwise obtained by, the Consumer Product Safety Commission 
which either contains or relates to a trade secret or is “subject to section 552(b)(4) of Title 5.” 15 U.S.C. §§ 2055(a)(2), 
2055(b)(1), 2055(b)(5). The Tariff Act authorizes withholding of certain “information submitted to the administering 
authority or the [United States International Trade] Commission which is designated as proprietary by the person 
submitting the information.” 19 U.S.C. § 1677f. The Aviation and Transportation Security Act authorizes withholding 
of information obtained or developed in carrying out security under the authority of the Aviation and Transportation 
Security Act or under chapter 449 of this title. 49 U.S.C. § 114(s). The Federal Aviation Act authorizes withholding of 
certain information obtained or developed in ensuring transportation security if disclosure of that information would 
constitute an invasion of personal privacy, reveal a trade secret or confidential commercial or financial information, or 
be detrimental to transportation safety. 49 U.S.C. § 40119(b). U.S. Department of Justice, Office of Information Policy,

the enactment of legislative exemptions from FOIA to enable regulated entities “to provide us 
with access to confidential information without concern that the information will later be made 
public.”35 Academics, government accountability groups, and some members of the public oppose 
the creation of legislative exemptions from FOIA on the grounds that such legislative exemptions 
from FOIA undermine the goals of government accountability and transparency and have “the 
potential to severely hinder the public’s ability to access critical information related to the 
oversight activities” of government.36 Agency FOIA decisions are believed by some proponents 
of legislative exemptions from FOIA to be ambiguous and discretionary.37 Private industry is also 
concerned about disclosure of confidential business information under state open records laws, 
and disclosure of sensitive corporate information to competitors.38 These concerns exist 
notwithstanding protections afforded in the Trade Secrets Act39 and the Critical Infrastructure 
Information Act.40 
Proponents of open records and government transparency argue that new exemptions from FOIA 
jeopardize the public’s ability to obtain information about government and industry practices, cast 
a shroud of secrecy over government’s functions, and are unnecessary because FOIA’s 
exemptions adequately protect private information from disclosure.41 The FOIA exemptions often

threats, and to promote information sharing to protect critical assets. The CIIA specifically excludes critical 
infrastructure information from disclosure under the FOIA. Subtitle B (Sec. 211 et seq.) of title II of P.L. 107-296, 116

cited as providing sufficient protection for confidential business information are the exemptions 
for national security information,42 trade secrets and confidential business information,43 law 
enforcement records,44 and bank examination information.45 The FOIA exemption for national 
security information is of relevance to public-private sector information sharing because much of

Homeland Security: Consideration of the Administration’s Proposal, 107th Cong., 2nd sess., June 25 and July 9, 2002, 
Serial No. 107-113 (Washington: GPO, 2002), p. 258. 
42 Exemption 1 of the FOIA protects from disclosure national security information concerning the national defense or 
foreign relations of the United States, provided that it has been properly classified in accordance with the requirements 
of an executive order. Under Executive Order 13526, “Classified National Security Information”, the President, Vice 
President, agency heads and any officials designated by the President, and United States government officials delegated 
authority may classify information upon a determination that the unauthorized disclosure of such information could 
reasonably be expected to cause identifiable or describable damage to the national security. Such information must be 
owned by, produced by or for, or under the control of the federal government, and must include one of the following: 
military plans, weapons systems, or operations; foreign government information; intelligence activities (including 
covert action), intelligence sources or methods, or cryptology; foreign relations or foreign activities of the United 
States, including confidential sources; scientific, technological, or economic matters relating to national security; 
United States government programs for safeguarding nuclear materials or facilities; vulnerabilities or capabilities of 
systems, installations, infrastructures, projects, plans, or protection services relating to national security; or the 
development, production, or use of weapons of mass destruction. Exec. Order No. 13526, 75 F.R. 707 (Jan. 5, 2010). 
43 Exemption 4 provides that the FOIA does not apply to matters that are “(4) trade secrets and commercial or financial 
information obtained from a person and privileged or confidential. 5 U.S.C. § 552(b)(4). Most exemption 4 cases have 
involved a dispute over whether the requested information was confidential. If disclosure of the information is likely to 
either impair the government’s ability to obtain necessary information in the future; or to cause substantial harm to the 
competitive position of the person from whom the information was obtained, the commercial information will be 
treated as confidential. See, National Parks and Conservation Association v. Morton, 498 F.2d 765 (D.C. Cir. 1974). In 
1992, in Critical Mass Energy Project v. NRC, 975 F.2d 871, 879-80 (D.C. Cir. 1992) (en banc) (“Critical Mass II”), 
cert. denied, 507 U.S. 984 (1993), the D.C. Circuit limited the scope and application of National Parks to cases in 
which a FOIA request is made for commercial or financial information a person was required to furnish to the 
government: information is exempt from disclosure if the submitter can show that it does not customarily release the 
information to the public. The Critical Mass voluntary vs. required standard has not been widely adopted. See U.S. 
Department of Justice, Freedom of Information Act Guide and Privacy Act Overview (May 2009), available at, 
http://www.justice.gov/oip/foia_guide09.htm. 
44 Exemption 7 provides that FOIA does not apply to matters that are 
(7) records or information compiled for law enforcement purposes, but only to the extent that the 
production of such law enforcement records or information (A) could reasonably be expected to 
interfere with enforcement proceedings, (B) would deprive a person of a right to a fair trial or an 
impartial adjudication, (C) could reasonably be expected to constitute an unwarranted invasion of 
personal privacy, (D) could reasonably be expected to disclose the identity of a confidential source, 
... , (E) would disclose techniques and procedures for law enforcement investigations or 
prosecutions, or would disclose guidelines for law enforcement investigations or prosecutions if 
such disclosure could reasonably be expected to risk circumvention of the law, or (F) could 
reasonably be expected to endanger the life or physical safety of any individual. 5 U.S.C. § 
552(b)(7). 
45 Exemption 8 provides that FOIA does not apply to matters that are “(8) contained in or related to examination, 
operating, or condition reports prepared by, on behalf of, or for the use of an agency responsible for the regulation or 
supervision of financial institutions.” 5 U.S.C. § 552(b)(8). The Administrative Conference of the United States 
recognized that “Exemption 8 provides an unusual level of protection to banks and bank regulatory agencies. Except 
for Exemption 9, dealing with geological and geophysical information, no other FOIA exemption is industry- or 
agency-specific. In light of the change in the regulatory environment of financial institutions since the passage of FOIA 
in 1966, the Conference has reviewed whether this broad exemption continues to be justified. The upheaval faced by 
financial institutions in the last decade and the number of such institutions that have failed makes availability of 
information relating to the regulation of that segment of the economy of particular interest. A substantial amount of 
taxpayer money has been spent to alleviate problems relating to financial institutions.” See Administrative Conference 
of the United States, “Recommendation 95-1: Application and Modification of Exemption 8 of the Freedom of 
Information,” 60 Federal Register 13692-13697, March 14, 1995.

the threat information is reportedly classified.46 The exemption for trade secrets and confidential 
business information is viewed by some as not providing the certainty of protection that 
submitters of sensitive or proprietary business information seek. On the other hand, proponents of 
government access contend that Exemption 4 provides a workable framework to adequately 
address those concerns. 
Congress has increasingly enacted Exemption 3 statutes containing disclosure prohibitions that 
are specifically directed toward FOIA. Exemption 3 provisions have been included in legislative 
proposals to encourage the private sector to provide information to the government with the 
assurance that the information that it has submitted will not be disclosed. In recent years 
legislative exemptions from FOIA were enacted for information concerning chemical facility 
security;47 chemical-terrorism vulnerability information;48 information obtained by the 
Biomedical Advanced Research and Development Authority (BARDA) to develop drug 
technologies and vaccines to respond to natural outbreaks and bioterrorism;49 animal 
identification systems;50 transportation security;51 food safety;52 securities regulation;53 and 
critical infrastructure protection.54

Many legislative exemption statutes have been found by courts to qualify as Exemption 3 statutes 
under FOIA.55 Agencies are required annually to list all Exemption 3 statutes utilized in their 
annual FOIA reports.56 Additionally, FOIA requires agencies to include in their annual FOIA 
reports “the number of occasions on which each statute was relied upon, a description of whether 
a court has upheld the decision of the agency to withhold information under each such statute, 
and a concise description of the scope of any information withheld.”57 
Exemption 3 Enactments in the 111th Congress. 
During the 111th Congress, two legislative exemptions from FOIA have been particularly 
controversial. The Protected National Security Documents Act of 2009, Section 565 of P.L. 111-
83, was enacted in response to litigation under FOIA to obtain photographs depicting the 
mistreatment or alleged mistreatment of detainees in Iraq and Afghanistan.58 It defines a 
“protected document” as  
any record for which the Secretary of Defense has issued a certification stating that 
disclosure of that record would endanger citizens of the United States, members of the 
United States Armed Forces, or employees of the United States Government deployed 
outside the United States; and is a photograph that was taken during the period beginning on 
September 11, 2001, through January 22, 2009; and relates to the treatment of individuals

not available for public inspection or copying, nor is information contained in those records released to the public. (b) 
Section 1520.7 describes the information that TSA prohibits from disclosure. The Administrator prohibits disclosure of 
information developed in the conduct of security or research and development activities under 49 U.S.C. § 40119 if, in 
the opinion of the Administrator, the disclosure of such information would: (1) Constitute an unwarranted invasion of 
privacy (including, but not limited to, information contained in any personnel, medical, or similar file); (2) Reveal trade 
secrets or privileged or confidential information obtained from any person; or (3) Be detrimental to the safety of 
persons traveling in transportation.... 49 C.F.R. § 1520.3. 
52 The Secretary shall compile and maintain an up-to-date list of facilities that are registered under this section. Such 
list and any registration documents submitted pursuant to this subsection shall not be subject to disclosure under section 
552 of title 5. Information derived from such list or registration documents shall not be subject to disclosure under 
section 552 of title 5 to the extent that it discloses the identity or location of a specific registered person. 21 U.S.C. §

A certification and a renewal of a certification expires three years after the date on which the

A provision in the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank 
Act), P.L. 111-203, that grants an exemption from FOIA to the Securities and Exchange 
Commission (SEC) for certain information received from entities it regulates and information 
used for other regulatory and oversight activities has generated a great deal of controversy.61 
Many questions have been raised regarding the scope and application of Section 929I of the 
Dodd-Frank Act, Protecting Confidentiality of Materials Submitted to the Commission. Some 
assert that Section 929I of the Dodd-Frank Act exempts the Securities and Exchange Commission 
from FOIA. The SEC contends that the provision is necessary in order to obtain confidential or 
sensitive business information from entities now subject to SEC regulation—hedge funds, private 
equity funds, and venture capital funds. 
Section 929I provides, 
(a) Except as provided in subsection (f), the Commission shall not be compelled to disclose 
records or information obtained pursuant to section 17(b), or records or information based 
upon or derived from such records or information, if such records or information have been 
obtained by the Commission for use in furtherance of the purposes of this title, including 
surveillance, risk assessments, or other regulatory and oversight activities. (2) 
TREATMENT OF INFORMATION- For purposes of section 552 of title 5, United States 
Code, this subsection shall be considered a statute described in subsection (b)(3)(B) of such 
section 552. Collection of information pursuant to section 17 shall be an administrative 
action involving an agency against specific individuals or agencies pursuant to section 
3518(c)(1) of title 44, United States Code. 
(b) Investment Company Act of 1940- Section 31 of the Investment Company Act of 1940 
(15 U.S.C. 80a-30) is amended ... 
Limitations on Disclosure by Commission- Notwithstanding any other provision of law, the 
Commission shall not be compelled to disclose any records or information provided to the 
Commission under this section, or records or information based upon or derived from such 
records or information, if such records or information have been obtained by the 
Commission for use in furtherance of the purposes of this title, including surveillance, risk 
assessments, or other regulatory and oversight activities. Nothing in this subsection 
authorizes the Commission to withhold information from the Congress or prevent the 
Commission from complying with a request for information from any other Federal 
department or agency requesting the information for purposes within the scope of

Commission from complying with a request for information from any other Federal 
department or agency requesting the information for purposes within the scope of

shall be an administrative action involving an agency against specific individuals or agencies 
pursuant to section 3518(c)(1) of title 44, United States Code.62 
As discussed above, The OPEN FOIA Act requires that when Congress provides for a statutory 
exemption to FOIA, Congress must state its intention to do so explicitly and clearly. The OPEN 
FOIA Act requires that any statute “enacted after the date of enactment of the OPEN FOIA Act of 
2009” must “specifically cite to this paragraph [5 U.S.C. § 552(b)(3)].” Section 929I does include 
language identifying the provision as an Exemption 3 statute. The Dodd-Frank Act provides that 
“[f]or purposes of section 552 of title 5, United States Code, this subsection shall be considered a 
statute described in subsection (b)(3)(B) of such section 552.” 
Chairman Frank of the House Financial Services Committee has scheduled a hearing on 
September 16, 2010, to consider concerns raised about the provision.63
