Protests Involving Limitation on Subcontracting Certifications in SDVOSB Procurements

September 3, 2026 Sareesh Rawat, Esq.

The limitations on subcontracting clause in federal contracts prohibits small businesses from subcontracting out more than a specified percentage of work to non-similarly situated entities. For contracts set-aside for service disabled veteran owned small businesses (SDVOSBs), the limitation on subcontracting clause may limit the prime contractor from subcontracting out more than 50% of the amount paid to it by the government to firms that are not certified SDVOSBs listed in the Small Business Administration (SBA) certification database as set forth in Veteran Affairs Acquisition Regulations (VAAR) 852.219-73 or certified veteran owned small businesses (VOSBs) listed in the SBA certification database as set forth in VAAR 852.219-74. The solicitations for these SDVOSB contracts require each offeror to submit a certification demonstrating its agreement to comply with the limitation on subcontracting terms. Such a certification imposes substantial legal obligations on the contractor and is accordingly considered a material solicitation term. An offeror’s failure to execute the limitation on subcontracting certification renders its proposal unresponsive because it fails to demonstrate an unequivocal commitment to be bound to perform, without exception, in accordance with the material terms and conditions of the solicitation. Therefore, the Government Accountability Office (GAO) will not sustain a protest if the protester is eliminated for failing to submit a properly executed limitation on subcontracting certification with its proposal.

In B-423106, a decision issued on January 16, 2025, the GAO denied a protest challenging the SDVOSB protester’s elimination from competition because the protester had failed to submit a signed limitation on subcontracting certification with its quotation. The Department of Veterans Affairs (VA) issued a request for quotation (RFQ) under the General Services Administration (GSA) Federal Supply Schedule (FSS) program for unarmed security guard services at the VA Medical Center in Orlando, Florida. The procurement was set aside for SDVOSB concerns under the Veterans First Contracting Program. The program’s implementing regulations at VAAR 819.7004 prohibit contracting officers (COs) from making an award without obtaining a certification from the offeror that it will comply with the solicitation’s limitations on subcontracting clause, which is later incorporated in the resultant contract. The RFQ included the limitations on subcontracting clause at VAAR 852.219-75, which in relevant part prohibited the contractor from paying more than 50% of the amount paid to it by the government to firms that were not certified SDVOSBs or VOSBs. The solicitation also required each vendor to submit a completed and signed certification stating that the vendor agreed to comply with the limitation on subcontracting terms. During the preliminary compliance review, the CO determined that the protester’s quotation was missing a signed limitation on subcontracting certification and excluded it from further consideration. The protester filed a timely post-award protest at the GAO.

The protester made two arguments relevant to the limitation on subcontracting certification requirement. Firstly, it argued that the solicitation did not explicitly require the submission of a signed certification. Secondly, and in the alternative, the protester argued that since it had submitted a limitation on subcontracting certification with its quotation but had inadvertently left it unsigned, its error was merely an administrative oversight that should have been remedied by a request for clarification. The GAO rejected both arguments, noting first that the procurement was set aside for SDVOSB concerns under the Veterans First Contracting Program. The RFQ included VAAR 852.219-75, which stated the pertinent limitations on subcontracting. The solicitation also included an unambiguous requirement for a limitation on subcontracting certification. Thus, the protester’s first argument was rejected as being wholly without merit based on GAO’s review of the solicitation’s plain language. The GAO also found the protester’s alternative argument unpersuasive, noting that when included in a solicitation, the limitation on subcontracting certification requirement is a material term of a solicitation because it imposes significant legal obligations on the contractor. Accordingly, an offeror’s failure to submit a signed limitation on subcontracting certification with its quotation when the RFQ specifically requires it is not considered an administrative error or one that can be resolved through clarifications. Rather, such a material omission could only be cured through discussions, not through clarifications, and in any event, the agency was under no obligation to seek clarifications or to conduct discussions with the protester. Consequently, the GAO denied the protest.

When required by a solicitation, the limitation on contracting certification is a material term that imposes substantial legal obligations on the contractor. An offeror’s failure to include a completed and signed limitation on subcontracting certification in such cases is considered a matter of acceptability or responsiveness because it can cause the procuring agency to conclude that the offeror has not agreed to comply with the relevant requirements. Since the limitation on subcontracting certification requirement is a material term, an offeror’s non-compliance cannot be resolved through clarifications. Furthermore, although the decision above involved a signature that was missing altogether, any issues with a signature on a limitation on subcontracting certificate are resolved under the Federal Acquisition Regulation (FAR) definition of a signature. That is, the signature must be a discrete, verifiable symbol of an authorized individual that, when affixed to the certification with the individual’s knowledge and consent, indicates a present intention to authenticate. In this regard, even if the appearance of the signature on the certification is somewhat ambiguous, a handwritten mark may nevertheless qualify as a valid signature if it can be traced back to the individual who possesses the requisite binding authority. Ultimately, it remains the offeror’s responsibility to submit an adequately written proposal that meets all the material terms of the solicitation. The limitation on subcontracting certification, when required by the solicitation, is one such material term that, if not satisfied, renders the offeror’s proposal unacceptable and unable to form the basis of an award.

Use and Validity of Electronic Signatures in Federal Procurement

March 7, 2024 Sareesh Rawat, Esq.

Federal Acquisition Regulation (FAR) 2.101 defines a signature as the discrete, verifiable symbol, including electronic symbols, of an individual that, when affixed to a writing with the knowledge and consent of the individual, indicates a present intention to authenticate the writing. The FAR provides that federal agencies may accept electronic signatures and records in connection with government contracts. Therefore, contracting officers (COs) possess the discretion to supplement electronic transactions with other media to meet the requirements of any contract action governed by the FAR. At the same time, the Electronic Signatures in Global and National Commerce (E-SIGN) Act of 2000 promotes the use of e-signatures in domestic and international commerce by establishing the legal equivalency of electronic records, signatures, and contracts with their paper counterparts. The E-SIGN Act applies to most commercial transactions, with a few exceptions. Notably, however, the E-SIGN Act does not apply to the Department of Defense (DOD) and specifically provides that federal agencies need not accept electronic signatures with respect to a government contract. Thus, while electronic signatures are regularly accepted in various contract actions across the federal procurement lifecycle, agencies are under no regulatory obligation to accept an electronic signature without reservation.

Protests Involving Limitations on Subcontracting Requirements

March 19, 2026 Sareesh Rawat, Esq.

Under the Federal Acquisition Regulation (FAR) limitations on subcontracting clause, small business contractors may not subcontract out more than a specified percentage of work to non-similarly situated entities, depending on the NAICS code assigned to the contract. For instance, the clause at FAR 52.219-14 obligates the contractor not to pay more than 50% of the amount paid to it by the government for the performance of services and supply contracts to non-similarly situated entities. In this regard, a similarly situated entity is one that, like the prime contractor, possesses the necessary socioeconomic designations required by the contract. Notably, a procuring agency’s judgment on whether a contractor can comply with the limitations on subcontracting clause is a question of responsibility, which is reviewed by the Small Business Administration (SBA). Meanwhile, the contractor’s actual compliance with the clause is a matter of contract administration. Thus, both these issues are not considered by the Government Accountability Office (GAO) under its bid protest function. However, where a proposal, on its face, should lead an agency to conclude that an offeror has not agreed to comply with the limitations on subcontracting clause, the matter is of the proposal’s responsiveness or acceptability. The GAO reviews such matters to determine whether a proposal affirmatively takes an exception to the limitations on subcontracting or otherwise demonstrates that the offeror does not intend to comply with them.

Agency Discretion in Seeking Clarifications in Negotiated Procurements

May 21, 2026 Sareesh Rawat, Esq.

Contractors participating in negotiated procurements have a responsibility to submit a well-written, complete proposal with sufficiently detailed information that clearly meets solicitation requirements and permits meaningful review by the agency. The obligation to submit a well-written proposal includes providing accurate information in the specific format outlined in the solicitation. Despite these obligations, offerors may make errors in their submissions. Under Federal Acquisition Regulation (FAR) 15.306, agencies may give offerors the opportunity to resolve minor or clerical errors in their proposals or clarify certain aspects if an award is to be made without conducting discussions. In this regard, clarifications are limited exchanges between the procuring agency and offerors that may occur when an award is to be made without discussions. Scenarios where the agency may seek clarifications include, but are not limited to when the pricing submission contains obvious clerical errors, the relevance of an offeror’s past performance information is not immediately clear, and the contracting officer (CO) comes across adverse past performance information to which the offeror has not had a previous opportunity to respond. However, contractors should be mindful that it is firmly within the agency’s discretion to engage in clarifications. An award may remain proper even if the agency chooses not to request clarification from an offeror whose proposal contains an error that could have been resolved by a clarification request.

Protests Involving Failure to Meet Material Solicitation Requirements

August 13, 2026 Sareesh Rawat, Esq.

Proposals that fail to satisfy the material terms of a solicitation for a negotiated procurement are considered unacceptable and may not form the basis of an award. It is well-established that it is the offeror’s responsibility to submit an adequately written proposal in accordance with the solicitation’s terms that contains all the required information. Despite this obligation, offerors may inadvertently omit necessary information from their proposals. Similarly, proposals may inadequately address or otherwise fail to convey information required by the solicitation. In such cases, the offeror risks adverse evaluation by the procuring agency or elimination from the competition altogether. Protests challenging the agency’s adverse decisions in such cases can have a low success rate because the Government Accountability Office (GAO) does not reevaluate proposals or substitute its judgment for that of the agency but only ensures the reasonableness of the evaluation against the stated evaluation criteria and applicable procurement laws and regulations. Contractors should also be mindful that their disagreement with the agency’s judgment alone is insufficient to establish the unreasonableness of the evaluation. Furthermore, while the agency may elect to seek clarifications, when a solicitation contemplates award without discussions, providing an opportunity for offerors to resolve even minor or clerical errors in their proposals is firmly within the agency’s discretion, as there is no automatic right to clarifications.
