Intervenor

An intervenor in a federal bid protest is the contractor whose award is being challenged, who has the right to participate in protest proceedings at the GAO, file submissions defending the agency's source selection decision, and obtain access to the administrative record under a protective order.

What is an Intervenor?

When a company files a bid protest challenging a contract award, the winning contractor, the awardee, is an interested party in the protest and is entitled to participate as an intervenor. The intervenor has a direct stake in the outcome: a successful protest could result in cancellation of its contract, reevaluation that changes the award, or a complete resolicitation that requires it to recompete.

At the GAO, the intervenor is notified of the protest and given the opportunity to file comments on the agency's report responding to the protest. The intervenor may argue in favor of the agency's source selection decision, challenge the protester's standing as an interested party, or independently brief the GAO on why the protest should be denied. The intervenor may also request access to protected materials under a protective order to review the protester's proposal and inform its response.

Intervenors are not required to participate, an awardee may choose to let the agency defend its procurement decision without filing separate submissions. However, active intervenor participation is generally advisable for high-value contracts where the outcome of the protest would materially affect the awardee's revenue.

Why Intervenors matter for government contractors

If you win a federal contract and a losing offeror protests, understanding your rights as an intervenor is essential. Failing to intervene means the agency alone defends the award, without the benefit of your perspective on why your proposal was superior. Active intervenor participation allows the winning contractor to present its own arguments, correct mischaracterizations in the protest, and protect the award it earned.

Example

A cybersecurity firm wins a $40 million DoD contract award. A competing firm files a GAO protest within 10 days, triggering an automatic stay. The winning firm's counsel enters the protest as intervenor within the GAO's participation window, files a submission arguing the protester's proposed approach contained a material deficiency the agency correctly identified, and requests access to the protester's proposal under the protective order. The GAO considers the intervenor's arguments alongside the agency's report and denies the protest.

Frequently Asked Questions

Is the awardee automatically notified when a protest is filed?

Yes. The GAO notifies the procuring agency upon receipt of a protest, and the agency is required to notify the awardee so it can elect to participate as an intervenor. Prompt notice allows the awardee to retain protest counsel quickly.

Can more than one party intervene in a bid protest?

Yes. In a multi-award procurement, multiple awardees whose contracts are challenged may each intervene. Additionally, another offeror whose competitive position could be affected by the protest outcome, for example, the next-ranked offeror who could benefit if the top awardee is displaced, may also seek intervenor status.

Does an intervenor have access to the protester's proposal?

Under a protective order, intervenors admitted as cleared counsel may access the protester's proposal and other protected materials in the administrative record. The intervenor's business personnel are subject to the same restrictions as the protester's counsel under the order.

What happens to the intervenor's contract if the protest is sustained?

The GAO's corrective action recommendation determines the outcome. The contract may be suspended pending reevaluation, the solicitation may be amended and reissued, or in rare cases the contract may be terminated. If reevaluation results in the same award to the intervenor, the contractor's contract is reinstated or continued.
