Demonstrating Reasonably Specific Detail on Vaughn Indexes in FOIA Litigation
A Recent Court Order Defines What a Vaughn Index Must Show to Withhold Privileged Information

The FOIA Dispute
The Barry Goldwater Institute for Public Policy Research made a FOIA request to the Department of Education for records relating to the $37.7 million fine against Grand Canyon University. Litigation followed over the records that were produced or withheld. The Institute claimed that the Department of Education did not meet its burden of proof to establish that certain FOIA exemptions apply. Barry Goldwater Inst. for Pub. Pol'y Rsch. v. United States Dep't of Educ., No. CV-24-00314-PHX-SMM, 2026 LX 62284 (D. Ariz. Feb. 25, 2026).
The case is a helpful example of how a federal agency must explain documents withheld under a recognized exception. FOIA exemptions logs–Vaughn Indexes–are very similar to privilege logs in eDiscovery. Both documents outline why a document was withheld, citing a specific exemption clause.
The Department of Education Enforcement Office oversees colleges that participate in FSA programs. The office’s investigation group ensures compliance with Title IV of the Higher Education Act of 1965. The attorneys group provide legal advice to carry out their mission.
The case centered on the DOE’s investigation into whether Grand Canyon University misrepresented the requirements of its online doctoral program. After the fine against the university, the Goldwater Institute made a FOIA request for communications about the DOE fines.
The Withheld Documents
The DOE withheld documents pursuant to FOIA Exceptions 5 and 7(A). Exception 5 includes the deliberative-process privilege, the attorney-client privilege, and the attorney-work-product privilege. Goldwater, at *23. The Vaughn Index’s descriptions for the deliberative process were summarized as follows:
(1) Strategic discussions concerning the Department's investigation into GCU which preceded any final agency decision (a) finding a violation of federal law, regulations, or program participation agreements or (b) enforcing federal law, regulations, or a program participation agreement when violated;
(2) Email communications concerning the Department's statements to the press on the GCU investigation, which preceded the final statements to the press;
(3) Email communications discussing the Department's potential response to communications from GCU's counsel which preceded the Department's formal responses to GCU;
(4) Discussion of other FSA matters involving GCU, all of which preceded the Department's decision to offer GCU a provisional PPA with conditions relating to the findings in the GCU Investigation as well as the finalization of that provisional PPA; and
(5) Email communications between the Department and the FTC regarding the GCU investigation wherein the parties exchanged information and recommendations related to the investigation which preceded the initiation of the fine action against GCU.
FOIA Exceptions to Production
There are nine categories of exceptions to justify withholding records from a FOIA production. The government has the burden of demonstrating the exception applies by providing “tailored reasons” and cannot make boilerplate or conclusory statements. Goldwater, at *18.
Exception 5 incorporates privileges available to government agencies in civil litigation. Goldwater, at *23. The “deliberative process privilege” includes "inter-agency or intra-agency memorandums or letters which would not be available by law to a party other than an agency in litigation with the agency." Id.
The “deliberative process” exception requires that the documents must be 1) pre-decisional and part of the decision-making process. “Pre-decisional” requires that the documents be prepared to assist in arriving at the decision. “Deliberative” means the disclosure of the information would expose the “agency's decision-making process in such a way as to discourage candid discussion within the agency and thereby undermine the agency's ability to perform its functions." In order to meet FOIA’s goals, this exception is limited for consistent efficient government operation. Goldwater, at *26.
A Vaughn Index must "describe the justifications for nondisclosure with reasonably specific detail, demonstrate that the information withheld logically falls within the claimed exemptions, and show that the justifications are not controverted by contrary evidence in the record or by evidence of [agency] bad faith.” Goldwater, at *29-30.
A Vaughn Index needs to show that 1) the materials at issue are covered by the deliberative process privilege, and 2) it is reasonably foreseeable that release of those materials would cause harm to an interest protected by that privilege. Goldwater, at *26-27.
The DOE’s Vaughn Index was Adequate for the Deliberative Process Privilege
The court reviewed each challenged entry on the Vaughn to determine whether the claimed privilege was adequately explained.
- For the first document challenged, the court held that the emails were sent before a final decision was made on the investigation.
- For the second, the court found the emails were strategic discussions about the investigation.
- For the third, documents contained "strategic discussions" and "impressions.” The court held that all were properly withheld as both pre-decisional and deliberative.
Logikcull Insight
This FOIA litigation case spotlights the importance of a Vaughn Index and what ensures an adequate Vaughn Index. It must be specifically tailored to describe the withheld information. These principles are very similar to the requirements for preparing a privilege or redaction log.
The nine FOIA Exceptions are defined under 5 U.S.C. § 552(b)(1)–(9):
- National Security and Foreign Policy
- Internal Agency Rules
- Statutory Exemptions
- Trade Secrets, Confidential Information, or Proprietary Information
- Inter-agency or Intra-agency Communications
- Personal Privacy
- Law Enforcement Records
- Bank Reports
- Geological and Geophysical Data
FOIA redactions are usually labeled with the corresponding Exception number. Logikcull now has new features for responding to FOIA requests:
Custom Redaction Formatting: Apply jurisdiction-specific styles, including transparent redactions that confirm withheld content without exposing sensitive data.
Set Default Redaction Code/Label per User: Users can define their preferred redaction label as default, ensuring consistency and saving time across projects.
Audit All Redaction Actions: Every redaction is tracked with a detailed audit trail, providing transparency and compliance for FOIA, GDPR, and other regulatory requirements.
Multiple Labels/Codes per Zone: Apply more than one label to a single redaction zone, supporting nuanced confidentiality needs such as overlapping legal privileges.
The key to a Vaughn Index is to ensure there are specific, tailored reasons for withholding the information. Logikcull empowers responding agencies to redact protected information, label those redactions with the relevant exemption, and provide the specific reasons in a custom field for a Vaughn Index.
