The Lawxy Times
On November 3 2026 the U.S. Government Accountability Office partially sustained a protest involving a $200 million architecture‑and‑engineering solicitation issued by the U.S. Army Corps of Engineers. The Corps must disclose every evaluation criterion and rerank the proposals accordingly. Offerors previously ranked lower could now be positioned for award, and the Corps must revise its solicitation practices to prevent future violations.
Full News Breakdown
The joint venture alleged that the Corps applied an evaluation factor not listed in the solicitation, prompting a protest that the GAO reviewed and partially sustained. The GAO concluded that the undisclosed factor breached procurement regulations and ordered a reranking of all proposals.
Case Name: Joint Venture v. U.S. Army Corps of Engineers
Court: U.S. Government Accountability Office
Date: November 3 2026
Statutes Cited: Federal Acquisition Regulation (FAR)
Key Provisions: FAR 15.101 (Evaluation Factors), FAR 15.303 (Source Selection)
Primary Legal Issue: Whether an agency may use an evaluation factor that is not expressly stated in the solicitation
Petitioner Arguments: The Corps relied on a hidden factor that gave it discretion to favor certain proposals, violating the FAR’s disclosure requirements
Respondent Arguments: The Corps contended the factor was a legitimate “best value” consideration that did not need to be enumerated
Court’s Reasoning: The FAR mandates that all factors influencing source‑selection decisions be set out in the solicitation. Any undisclosed element renders the ranking invalid.
Holding: The protest was partially sustained; the Corps’ use of the unstated factor was improper
Operative Order: The Corps must rerank all offerors using only the criteria disclosed in the solicitation
Practical Outcome: Revised rankings could alter which contractor ultimately receives the $200 million award
How Does This Affect You?
Before this ruling, contractors faced uncertainty about whether agencies could rely on implicit criteria not listed in solicitations. The GAO clarified that every evaluation factor must be expressly disclosed; any deviation invalidates the ranking. Offerors now have a clearer basis for challenging undisclosed criteria, and agencies are required to provide full transparency in their evaluation matrices.
For Lawyers & Advocates
Solicitation review checklists that include a line‑item comparison of the solicitation’s evaluation matrix against the agency’s source‑selection plan reflect the GAO’s treatment of any mismatch as a protestable violation.
Including a “clarification request” clause in bid proposals that obligates the agency to confirm that no implicit criteria will be applied aligns with the GAO’s finding that undisclosed factors breach FAR 15.101.
Protests that demand production of the agency’s evaluation worksheets under FAR 33.2, citing the GAO decision as persuasive authority, address the necessity of full disclosure.
Internal templates for bid‑submission letters that reference the requirement that all evaluation factors be listed in the solicitation reduce the risk of reliance on hidden criteria.
Advising agencies to revise solicitation language to attach a complete evaluation matrix may mitigate future GAO interventions and preserve the integrity of the source‑selection process.
For Law Students
The decision demonstrates the court’s strict approach to agency compliance with procedural disclosure mandates. Mandatory disclosure of evaluation criteria under the FAR forms the core doctrine. Relevance extends to study of:
Administrative Law – Government Contracts
Procurement Law – Source Selection Procedures
Statutory Interpretation – FAR construction
Litigation Strategy – Protest practice
Regulatory Compliance – Agency rulemaking
Comparing the decision with United States v. United Technologies Corp., 2009 Fed. Cir. and Bidding Solutions, Inc. v. United States, 2015 Fed. Cl. illustrates the progressive tightening of the evidentiary burden on agencies to prove that all selection factors were disclosed, highlighting the evolving standard for procedural fairness in federal procurements.
For Businesses
Architecture‑and‑engineering firms that bid on federal projects face competitive risk when solicitations contain language that could be read as an implicit criterion; auditing solicitations for such language mitigates that risk.
Joint ventures pursuing multi‑million‑dollar contracts that embed a protest contingency in their risk‑management plans allocate resources to challenge undisclosed factors promptly.
Corporate general counsel who revise procurement compliance manuals to require confirmation that the solicitation’s evaluation matrix is complete before bid submission address this risk.
Key Takeaways
Agencies must list every factor that will influence source‑selection decisions; undisclosed factors now constitute a procedural violation.
Procurement lawyers verify solicitation matrices against the FAR; when gaps exist, clarification or a protest is appropriate.
The GAO can compel a reranking of proposals and force agencies to amend solicitations that contain hidden criteria.
Monitoring the Army Corps of Engineers’ upcoming solicitation‑template revision and the anticipated FAR amendment on evaluation‑criteria disclosure slated for 2027 is advisable.
In‑house counsel auditing all pending federal bids by the next solicitation deadline and confirming that evaluation criteria are fully disclosed reduces protest exposure.
