The Bid Protest Debrief
In Metro East Joint Venture, LLC, B-424392 (April 21, 2026), Metro East Joint Venture LLC (Metro) protested the issuance by the Centers for Disease Control and Prevention (CDC) of a sole-source contract modification to incumbent Chenega Global Protection LLC (Chenega) for guard services at the CDC’s Atlanta and Fort Collins campuses. Metro argued that the sole-source extension was contrary to law and regulation, that the agency failed to address conflicts of interest, and that the CDC had unduly delayed implementing the corrective action it promised in response to Metro’s earlier protest.
After Metro filed an initial protest in December 2025 challenging an earlier proposed sole-source action, the CDC announced corrective action. The CDC, however, subsequently posted a new sole-source notice on SAM.gov on January 27, 2026, attaching a redacted justification that spelled out a base period through March 30, an option period through June 30, and the possibility of further performance through the inclusion of FAR 52.217-8 (Option to Extend Services). When the CDC exercised the initial option period on March 25, Metro filed the instant protest within 10 days of that action, on April 6. GAO nonetheless dismissed the protest as untimely, holding that Metro should have protested within 10 days of the January 27 notice—when it first learned that the CDC had reserved the option to extend performance—not within 10 days of when the CDC actually exercised that option on March 25. This decision provides a useful primer on when the protest clock starts running on a potential sole-source action that is telegraphed in advance.
The Decision
GAO dismissed the protest, ruling that:
- The 10-Day Clock Started with the SAM.gov Notice and Justification: GAO reaffirmed that a protest based on other than alleged solicitation improprieties must be filed within 10 calendar days of when the protester knew, or should have known, the basis for protest. Here, the CDC’s January 27 SAM.gov notice—which expressly identified Chenega as the intended awardee and attached a redacted sole-source justification—gave Metro actual notice of the sole-source modification, the agency’s rationale and the period of performance at issue. As such, GAO held that Metro’s April 6 filing came more than two months too late.
- Conflict-of-Interest Allegations Were Untimely Because They Were Already Known: GAO highlighted that Metro’s OCI arguments were “substantively indistinguishable” from those raised in its earlier protest of the agency’s previously proposed (and then rescinded) sole-source actions involving Chenega. Thus, because nothing about those allegations turned on information unavailable on January 27, GAO held that Metro was required to raise them within 10 days of that notice. Having failed to do so, the arguments were found untimely.
- Challenges to the Sole-Source Justification Itself Had to Be Filed Within 10 Days of the SAM.gov Posting: To the extent Metro objected to the agency’s stated rationale for limiting competition under FAR 6.302-1 (only one responsible source), GAO similarly held that Metro was required to file at GAO within 10 days of the January 27 SAM.gov notice and accompanying redacted justification. Filing more than two months later in April after the option period was exercised was too late, even though the option exercise was the trigger Metro relied on.
- “Undue Delay in Implementing Corrective Action” Was Also Time-Barred: Metro’s most creative argument was that, by exercising the first option period, the CDC had unreasonably delayed implementing the corrective action it offered in response to Metro’s earlier protest. GAO was not persuaded, noting that the January 27 notice and accompanying justification clearly disclosed that Chenega could perform through at least June 30 by exercise of the option, and that it even contemplated additional extensions under FAR 52.217-8. Thus, because the possibility of extended sole-source performance was clear on the face of the January 27 documents, GAO held that any protest regarding undue delay had to be filed within 10 days of that notice. In other words, Metro could not wait to see whether the option would actually be exercised before filing a protest.
- “Premature and Not Ripe” Is Not a Get-Out-of-Jail-Free Card: Metro argued that any earlier protest would have been premature so long as the CDC was making “significant progress toward a competitive procurement.” GAO rejected that argument, finding that the agency’s January 27 notice “expressly provided that performance could extend to June 30, at least,” and that Metro could not sit on its rights and wait until the agency actually pulled the trigger on the option. Notably, GAO added a footnote reminding agencies that a “mere promise of corrective action, without reasonably prompt implementation, circumvents the goal of the bid protest system established by CICA.” While this could be viewed as a shot across the bow for future agency conduct, it could not save Metro’s untimely protest.
Key Takeaways for Contractors
- Treat the SAM.gov Sole-Source Notice as the Starting Gun: Once an agency posts a notice of intent to award sole-source award under FAR 6.302-1 and makes its (even redacted) justification available, the GAO’s 10-day clock starts ticking for all potential arguments.
- Read the Justification for the Full Scope of Performance: If the J&A discloses option periods or a FAR 52.217-8 extension, you cannot wait for the agency to actually exercise the option to challenge it.
- Don’t Assume “Premature” Protects You: Arguments that a sole-source challenge would be “premature” or “not ripe” while the agency is supposedly moving toward competition will not toll the clock. If the agency has signaled the path it intends to take, and it seems improper, file now. In this regard, it’s better to be early than late.
- Corrective Action Promises Are Not Self-Enforcing: GAO will hold agencies to “reasonably prompt implementation” of promised corrective action, but contractors must still police that obligation through timely follow-on protests filed within 10 days of learning that the corrective action plan is not being followed.
