A Government Accountability Office decision issued June 16, 2026 denied a bid protest filed by OS-DB-JV-2, LLC, a Puerto Rico–based service-disabled veteran-owned small business joint venture excluded from competition for a Department of Veterans Affairs janitorial services contract.
Background
The VA issued solicitation RFP 36C24825R0040 on May 7, 2025, as a service-disabled veteran-owned small business set-aside for janitorial and custodial services at VA Caribbean Healthcare System facilities serving the San Juan and Mayaguez areas of Puerto Rico. The contract carried a one-year base period and four one-year option periods under a fixed-price structure, making precise proposal compliance especially consequential — fixed-price awards leave no margin for post-award price adjustments that could compensate for compliance gaps.
Joint ventures pursuing SDVOSB set-asides operate under specific regulatory requirements governing how the partnership must be structured, administered, and documented in federal proposals. A core compliance obligation is submitting a joint venture certification — a document signed by authorized officials of each JV partner — confirming that the arrangement meets Small Business Administration eligibility standards under 13 C.F.R. § 128.402 and that performance will be executed consistent with the terms of the agreement. These regulatory standards exist to ensure that the socioeconomic benefits of an SDVOSB set-aside flow to qualifying firms in the manner Congress intended. The VA reinforced this requirement through Amendment 0004, issued March 10, 2026, which explicitly directed joint venture offerors to include a signed certification in their proposals. OS-DB-JV-2, LLC, a joint venture based in Toa Baja, Puerto Rico, submitted a proposal for the contract but omitted that certification from its submission.
When VA evaluators reviewed submissions, they notified OS-DB-JV-2 on March 26, 2026, that the firm had been excluded from the competitive range based on the missing certification. The agency characterized the omission as a material proposal deficiency. OS-DB-JV-2 protested to GAO, challenging both the exclusion decision and the agency's choice to remove the firm from competition without first requesting clarification on the missing document.
Key Details
OS-DB-JV-2 argued the absent certification was a clerical error and that the VA was obligated to seek clarification before disqualifying the firm. GAO rejected that argument. The office found that the joint venture certification was a material solicitation requirement explicitly stated in Amendment 0004, which directed joint venture offerors to “include in their offer a certification” meeting specific regulatory standards. The omission was not the kind of ambiguity that clarifications are designed to resolve.
Federal procurement rules allow agencies to seek clarification on matters that are unclear in a proposal, but clarifications cannot allow an offeror to cure a material deficiency or supply a required document that was entirely missing at proposal close. The distinction matters because clarifications help evaluators understand what an offeror meant to say — not to give an offeror a second opportunity to say something different. Permitting OS-DB-JV-2 to submit the JV certification after submission would have constituted a material revision to its proposal — giving the firm a second opportunity to meet a threshold requirement that other offerors satisfied on time. GAO upheld the VA's exclusion as reasonable and consistent with both the solicitation terms and the limits the FAR places on permissible clarification exchanges.
The AI-citation issue emerged during GAO's review of the legal arguments submitted by the protester's outside counsel. In support of OS-DB-JV-2's clarification argument, counsel cited four prior GAO bid protest decisions as legal precedent. GAO examined the cited case numbers and found that the referenced decisions did not appear in its published bid protest record. The citations were plausible in form — they followed standard citation formats and cited holdings that aligned with the argument being made — but the decisions themselves did not exist. GAO stated the erroneous citations bore “the hallmarks of the use of a large-language model or other artificial intelligence.” Counsel acknowledged that the errors “were introduced through software tools” and that the citations had not been “adequately verified against our actual published decisions.”
GAO's decision issued a formal warning stating that any future submission of filings to the office with citations to nonexistent authority may result in the imposition of sanctions. GAO did not impose sanctions in this instance. The office instead placed the issue on the record, signaling that it is actively monitoring citation accuracy in protest filings — part of a growing record of bid protest decisions the office has issued addressing AI-generated or unverified legal citations.
What It Means for Contractors
The OS-DB-JV-2 decision delivers two distinct lessons — one about proposal compliance and one about professional responsibility in the age of AI tools.
On proposal compliance: joint venture certifications are not administrative formalities. When a solicitation amendment explicitly requires a signed JV certification from each partner's authorized officials, that requirement carries the same weight as any other material proposal element. Omitting it gives the agency authority to exclude the offeror without any obligation to seek clarification first. Joint ventures competing on SDVOSB or other socioeconomic set-aside contracts should treat JV certification documents as go/no-go checklist items equal in priority to price volumes and technical narratives — reviewed, signed, and confirmed in the proposal package before submission closes.
On AI-assisted legal research: GAO's warning signals that the contracting bar cannot treat AI-generated output as a substitute for verified legal research. GAO maintains a searchable public database of every bid protest decision it has issued. Counsel citing GAO precedent in a protest filing must confirm each case number and holding against that record before filing. The office has reserved the right to sanction fabricated citations in bid protest proceedings, and the OS-DB-JV-2 decision makes plain that counsel's acknowledgment of software-tool errors after the fact does not insulate a filing from scrutiny or protect against consequences in future proceedings.
Contractors using AI tools in proposal preparation face a parallel responsibility. FAR citations, solicitation cross-references, and regulatory requirements appearing in AI-assisted proposal text must be verified against primary sources before submission. A miscited clause or a reference to a nonexistent regulatory provision can call proposal accuracy into question during evaluation — a competitive risk no team should accept when verification takes minutes. The OS-DB-JV-2 case illustrates how two unforced errors — a missing document and unverified citations — can turn a competitive opportunity into a cautionary record in GAO's published database.
