DOJ Clarifies FOIA Exemptions for Contractor Confidential Data
The DOJ’s Office of Information Policy released updated guidance on FOIA Exemption 4 for contractor data.
Why it matters: Agencies and legal teams for federal contractors must strictly apply revised FOIA Exemption 4 standards or risk unauthorized release of trade secrets, especially after the Supreme Court’s 2019 Argus Leader ruling.
- Exemption 4 shields confidential trade secrets and financial data provided to federal agencies.
- The DOJ’s June 2022 guidance outlines steps for identifying and protecting confidential contractor information.
- After Food Marketing Institute v. Argus Leader (2019), data must be customarily treated as private and given under assurance of confidentiality to qualify.
- Agencies must notify contractors when FOIA requests target their confidential information and allow objections before disclosure.
The U.S. Department of Justice’s Office of Information Policy (OIP) has reinforced protections for confidential commercial and financial information under the Freedom of Information Act (FOIA) Exemption 4. This exemption is central for federal contractors concerned about trade secrets and sensitive business data shared with government agencies.
- Exemption 4 prevents the disclosure of trade secrets or confidential business details, as recognized in the DOJ’s official FOIA guidance.
- Confidential status requires contractors to mark data as proprietary and show it is "customarily and actually treated as private," as clarified by the Supreme Court in Food Marketing Institute v. Argus Leader Media (2019).
The DOJ’s June 2022 memo calls for agencies to rigorously apply Exemption 4 and to establish “reverse FOIA” procedures:
- Agencies must provide pre-disclosure notice to contractors whenever a FOIA request could expose their confidential data, allowing time to object.
- Legal teams should advise contractor clients to consistently designate and document confidential information before submission to the government.
- Failure to follow these steps risks unprotected release and potential harm to competitive interests.
Nicholas T. Solosky, writing for Fox Rothschild, summarizes: "Federal agencies are required to disclose any information requested under FOIA — unless it falls under one of nine exemptions. Exemption No. 4 protects trade secrets and/or a contractor’s commercial or financial information that is confidential or privileged." Read more from Fox Rothschild.
By the numbers:
- 9 — Total FOIA exemptions; Exemption 4 covers confidential commercial info
- 2019 — Year of Supreme Court’s Argus Leader ruling clarifying 'confidential' standard
- 2022 — DOJ’s latest FOIA Exemption 4 guidance issued
Yes, but: Contractors who fail to document confidentiality or disclose data without proper assurance may lose protection under Exemption 4.
What's next: DOJ is encouraging agencies to update their internal FOIA regulations in line with the new guidance.
