Multiple Post-Argus Decisions Hold No “Assurance of Confidentiality” Required for FOIA Exemption 4

Client Alert | 1 min read | 08.06.21

In a string of recent cases following the Supreme Court’s 2019 decision in Food Marketing Institute v. Argus Leader Media, multiple courts have held that a party submitting information to the government need not demonstrate it obtained an assurance of confidentiality from the government in order for the agency to justify withholding that information in response to an information request made under the Freedom of Information Act (FOIA).  (Crowell & Moring previously wrote about the new test instituted by Argus Leader here.) 

FOIA Exemption 4 allows agencies to withhold documents otherwise responsive to a FOIA request if the documents contain “trade secrets and commercial or financial information obtained from a person [that is] privileged or confidential.”  As discussed in our previous post analyzing the Argus Leader decision, the Supreme Court had left open the question of whether the submitting party must have received some assurance from the government that the information would be kept confidential.  Recently, in The Washington Post v. U.S. Small Business Administration, the District of Columbia District Court followed the lead of other post-Argus Leader decisions in “declin[ing] to ‘read the word confidential to impose a blanket requirement that the government provide an assurance of privacy in every case in which it asserts Exemption 4.”  This ruling follows the court’s observation in Renewable Fuels Assoc. v. U.S. Environmental Protection Agency that “no court has yet held that ‘privately held information lose[s] its confidential character for purposes of Exemption 4 if it's communicated to the government without’ privacy assurances.”  These decisions signal that no “assurance of confidentiality” requirement currently exists.

Eleventh Circuit Hears Argument on False Claims Act Qui Tam Constitutionality

On the morning of December 12, 2025, the Eleventh Circuit heard argument in United States ex rel. Zafirov v. Florida Medical Associates, LLC, et al., No. 24-13581 (11th Cir. 2025). This case concerns the constitutionality of the False Claims Act (FCA) qui tam provisions and a groundbreaking September 2024 opinion in which the United States District Court for the Middle District of Florida held that the FCA’s qui tam provisions were unconstitutional under Article II. See United States ex rel. Zafirov v. Fla. Med. Assocs., LLC, 751 F. Supp. 3d 1293 (M.D. Fla. 2024). That decision, penned by District Judge Kathryn Kimball Mizelle, was the first success story for a legal theory that has been gaining steam ever since Justices Thomas, Barrett, and Kavanaugh indicated they would be willing to consider arguments about the constitutionality of the qui tam provisions in U.S. ex rel. Polansky v. Exec. Health Res., 599 U.S. 419 (2023). In her opinion, Judge Mizelle held (1) qui tam relators are officers of the U.S. who must be appointed under the Appointments Clause; and (2) historical practice treating qui tam and similar relators as less than “officers” for constitutional purposes was not enough to save the qui tam provisions from the fundamental Article II infirmity the court identified. That ruling was appealed and, after full briefing, including by the government and a bevy of amici, the litigants stepped up to the plate this morning for oral argument....
