GAO Bid Protests Under FAR 33.104: Timelines and Award Stays Walkthrough
When federal contracting decisions face formal challenges, contractors and agencies operate under rigid statutory and regulatory procedures. Under Federal Acquisition Regulation subpart 33.1, specifically FAR 33.104, protests filed with the Government Accountability Office (GAO) trigger structured schedules, document disclosure mandates, and statutory stays that directly control whether work begins, halts, or proceeds. Navigating these requirements requires a clear, step-by-step understanding of how the process unfolds from initial filing to final decision.
Step 1: File at GAO and Deliver Agency Notice Within 1 Day
Procedures governing protests at the GAO are grounded in 4 CFR Part 21, which controls if any procedural conflict arises with FAR guidance. The first critical operational step falls on the protester: when filing a challenge, the firm must deliver a complete copy of the protest to the official designated in the solicitation, or to the contracting officer if no specific official is identified. This submission must be received no later than 1 day after the protest is filed with the GAO. Missing this initial window carries immediate risk, as the GAO may dismiss the filing entirely if the protester fails to provide that copy within 1 day.
Immediately after the procuring agency receives written notice from the GAO confirming that a protest has been filed, the agency must notify other stakeholders. If the contract has already been awarded, the agency notifies the contractor. If award has not occurred, notice goes to all parties with a reasonable prospect of receiving the award if the protest is denied. Protesters seeking protection for proprietary data must request a protective order as soon as practicable, prompting the contracting officer to secure a redacted filing for release to interested parties.
Step 2: Establish the Pre-Award or Post-Award Stay
One of the most consequential aspects of a protest filed directly with the GAO is the automatic stay, which prevents procurement actions from moving forward while the review is pending. Estimators and project executives tracking these disputes can consult our review of GAO Bid Protest Deadlines for broader timing strategies.
- Pre-Award Protests: Under FAR 33.104(b), when an agency receives notice from the GAO before award, the contract may not be awarded. The agency can only bypass this restriction if authorized by the head of the contracting activity on a nondelegable basis. This override requires a written finding that urgent and compelling circumstances significantly affecting national interests will not permit awaiting a decision, and award is likely within 30 days. The agency must notify the GAO before authorizing the award.
- Post-Award Protests: Under FAR 33.104(c), when the agency receives notice from the GAO within 10 days after contract award, or within 5 days after a debriefing date offered under FAR 15.505 or FAR 15.506 (whichever date is later), the contracting officer must immediately suspend contract performance or terminate the contract.
If notice arrives after those specific windows, the contracting officer is not required to suspend performance or terminate the contract unless they determine that the award might be invalidated and a delay is not prejudicial to government interests.
Step 3: Compile the Agency Report Within 30 Days
Once notified by telephone from the GAO that a protest has been lodged, the contracting officer must compile the official protest file and agency report. The agency is required to submit its complete report to the GAO within 30 days after that telephone notice, or within 20 days if the GAO determines to use its express option. The GAO can shorten this if dismissed or grant documented extensions upon agency request.
The core protest file includes the protest itself, the protester's offer, the contested offer, relevant evaluation records, the solicitation specifications, and the abstract of offers. When a protester requests specific procurement records, the agency must provide a disclosure list to all parties and the GAO at least 5 days prior to filing the report, identifying documents released or withheld. Any objections to this proposed disclosure scope must be submitted to the GAO within 2 days after receiving that list.
Step 4: Manage Document Exchanges and Protective Orders
Simultaneously with its report submission to the GAO, the agency must send copies to the protester and intervening parties, omitting only classified data, competitive advantage information, or documents shielded by protective orders. The GAO may issue protective orders restricting the disclosure of sensitive commercial information, trade secrets, or procurement data. Within 2 days of a protective order request, participating parties can request exclusions or additions of individuals and documents.
If the protester identifies additional relevant documents, it must request them within 2 days of knowing (or when it should have known) of their existence. The procuring agency is then required to provide those documents to the GAO, protester, and interested parties within 2 days of receiving the request, or state in writing why specific files are withheld.
Step 5: File Comments and Await the 100-Day Decision
After the agency report is submitted, participating parties review the agency's factual statement and legal memorandum. Protesters and intervenors must submit comments on the agency report directly to the GAO within 10 days of receipt, or within 5 days if the express option is active. If the GAO convenes a formal hearing, written comments on both the hearing and report are due within 5 days of the hearing's conclusion.
By regulation, the GAO issues its formal recommendation within 100 days from the filing date, or within 65 days under the express option. If the agency decides not to follow the outcome, FAR 33.104(g) requires action: should the agency fail to fully implement GAO recommendations within 60 days of receipt, the head of the contracting activity must formally report the failure and its rationale to the GAO not later than 5 days after the 60-day window expires. When considering early dispute options before turning to external forums, contractors can also evaluate procedures under FAR 33.103 agency-level protests.
