    FAR 5.406Public disclosure of justification documents for certain contract actions.

    Plain-English Summary

    FAR 5.406 is a publication-and-transparency cross-reference rule. It tells contracting personnel when justification documents must be publicly posted for three different kinds of noncompetitive or limited-competition actions: (1) justifications and approvals for other than full and open competition, (2) limited-source justifications for Federal Supply Schedule (FSS) orders or blanket purchase agreements (BPAs) above the simplified acquisition threshold, and (3) justifications for task or delivery orders above the simplified acquisition threshold that are awarded without providing fair opportunity. The section does not create the substantive justification standards themselves; instead, it directs readers to the specific FAR provisions that control posting requirements and timing. In practice, this means agencies must ensure the required justification is not only prepared and approved, but also posted in the correct place and under the correct rule set so the public can review the basis for the restricted competition. For contractors, the section matters because it signals when an agency’s sole-source, limited-source, or fair-opportunity exception rationale should become publicly visible. For contracting officers, it is a compliance checkpoint that helps avoid protest risk, audit findings, and improper award processing.

    Key Rules

    Post J&A for full-and-open exceptions

    Justifications and approvals supporting other than full and open competition must be posted under FAR 6.305. This section points to the public posting requirement for those J&As rather than restating the detailed timing and content rules.

    Post limited-source FSS/BPA justifications

    Limited-source justifications for FSS orders or BPAs, excluding brand-name justifications, must be posted when the estimated value exceeds the simplified acquisition threshold. The posting must follow FAR 8.405-6(a)(2).

    Post fair-opportunity exceptions

    Justifications for task or delivery orders above the simplified acquisition threshold that are awarded without providing fair opportunity must be posted under FAR 16.505(b)(2)(ii)(D). This covers orders placed under multiple-award vehicles when an exception to fair opportunity is used.

    Threshold matters

    The simplified acquisition threshold is a key trigger in this section. Whether a justification must be publicly posted depends in part on whether the action exceeds that threshold.

    Cross-reference only

    FAR 5.406 is a coordination provision, not a standalone justification standard. The actual requirements for approval, content, and timing are found in the cited FAR sections.

    Responsibilities

    Contracting Officer

    Determine whether the action falls under other-than-full-and-open competition, a limited-source FSS/BPA action, or a task/delivery order exception to fair opportunity. Prepare or obtain the required justification, secure the proper approval, and ensure the document is posted in accordance with the applicable FAR citation.

    Approving Official

    Review and approve the justification when the applicable FAR part requires approval at a specified level. Ensure the rationale is legally and factually sufficient before the document is released for posting.

    Agency

    Maintain the public posting process and comply with the applicable FAR posting procedures and timelines. Ensure the justification is made available in the correct public forum or system required by the referenced FAR provision.

    Contractor

    Understand that certain sole-source, limited-source, or fair-opportunity exception rationales may be publicly posted. Review posted justifications when relevant to market awareness, competition strategy, or protest considerations.

    Practical Implications

    1

    This section is a compliance checkpoint: if the justification is not posted correctly, the award can be vulnerable to protest or audit scrutiny even if the underlying rationale is otherwise valid.

    2

    The biggest operational mistake is using the wrong FAR citation or posting process for the type of action involved; each category has its own controlling rule.

    3

    Contracting officers must watch the threshold carefully, because the posting requirement for limited-source FSS/BPA actions and fair-opportunity exceptions turns on whether the estimated value is above the simplified acquisition threshold.

    4

    Because the rule is about public disclosure, agencies should treat the justification as a document that may be read by competitors, oversight officials, and the public, so it should be clear, complete, and internally consistent.

    5

    Contractors should monitor posted justifications to better understand agency buying patterns, identify potential protest issues, and assess whether future opportunities may be competed more broadly.
