Bid protests: GAO and the Court of Federal Claims
A bid protest is a challenge to how a federal agency awarded a contract or ran a competition. Depending on the facts and the clock, it can be filed with the agency, with the Government Accountability Office, or in the U.S. Court of Federal Claims.
This guide is a map, not the rule. It tells you where a protest is filed and where the primary text lives.
Where a protest is filed
- At the agency. An agency-level protest is decided by the contracting agency itself.
- At GAO. The Comptroller General decides bid protests under the Competition in Contracting Act; the procedure is the GAO Bid Protest Regulations at 4 CFR Part 21. GAO publishes its decisions and its bid-protest process, including the deadlines for filing and its express-option timetable.
- In the Court of Federal Claims. A protester may also sue in the U.S. Court of Federal Claims, whose jurisdiction over contract claims comes from the Tucker Act, 28 U.S.C. § 1491.
The deadlines are the case
Bid-protest practice turns on timing more than on anything else. The GAO regulations set short filing windows — for example, a protest based on something the protester knew or should have known is generally due within days, and a challenge to the terms of a solicitation has its own deadline tied to the closing date. Those windows are stated in 4 CFR Part 21; read them there, because a late protest is a dismissed protest.
Why it matters for your next bid
Protest decisions are where agencies get told, in public, what a clean competition looks like — evaluation, conflict of interest, past performance, discussions. Reading them is how a contractor learns what to put in a proposal and what to challenge. Our desks watch the decisions and the trends, and state a position rather than a hedge.
