GAO Clarifies Timeliness of Preaward Protests Challenging Solicitation Amendments

Client Alert | 1 min read | 07.01.20

In Computer World Services Corporation, GAO sustained a protest challenging the Department of Homeland Security, U.S. Coast Guard’s corrective action taken in response to an earlier sustained protest by CWS. In its original protest, CWS successfully challenged a task order award; in response, the agency informed offerors via e-mail that it intended to remove a limited price realism analysis from its evaluation, and requested that offerors revalidate their price quotes within two days. The agency did not, however, issue a formal solicitation amendment or provide offerors with an opportunity to submit revised quotes.

CWS challenged the announced corrective action ten days later, alleging that the agency had materially changed its evaluation methodology without providing an opportunity for proposal revisions, and that the agency’s accompanying abandonment of reliance on an Independent Government Estimate (IGE) for its price realism evaluation was unreasonable. As a threshold matter, GAO determined the protest was timely, because the agency’s request for validation did not constitute a proposal deadline, meaning its change in evaluation approach was subject to GAO’s 10-day “known or should have known” timeliness rule. GAO then determined that elimination of the price realism component of the evaluation constituted a material change to the RFQ, requiring the agency to solicit revised quotations.

With respect to CWS’ second challenge, that the agency should be required to develop a new IGE, GAO concluded the allegation was premature. GAO explained that CWS’ true concern related to success of the agency’s reevaluation, which could not be reviewed until it was actually conducted.

Bidders should closely monitor agency corrective action to assess new protest filing deadlines. Failure to timely challenge changes to evaluation methodology may prevent offerors from later arguing that those changes were improper.

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....
