What is a bid protest?

A bid protest is a formal challenge to a federal procurement decision — typically the award of a contract to a competitor or the terms of a solicitation. Protests are filed with the agency, the Government Accountability Office (GAO), or the Court of Federal Claims. Successful protests can reverse awards or force agencies to re-compete.

Federal bid protests are governed by FAR Part 33 and the Competition in Contracting Act. A protest is an objection to: - The terms of a solicitation (pre-award protest) - The award of a contract to a specific vendor (post-award protest) - The cancellation of a solicitation

Three forums hear federal bid protests:

Agency-level protest: filed directly with the contracting officer. Fast (10-day decision typically), but the agency rules on its own decision — protest sustain rates are low.

Government Accountability Office (GAO): the standard forum for serious protests. GAO decisions take 100 days. Filing fee is nominal. GAO will recommend (not order) the agency to take corrective action; agencies almost always follow GAO recommendations. The act of filing a GAO protest triggers an automatic stay of contract performance in most cases — which alone can be valuable.

Court of Federal Claims (COFC): the highest forum, used for complex protests, when GAO has already ruled, or when injunctive relief is needed. COFC proceedings are slower (months) and more expensive (litigation), but COFC issues binding decisions.

Common grounds for protest: - Solicitation requirements that unduly restrict competition - Improper evaluation of proposals (the agency misapplied the stated factors) - Improper conduct by the contracting officer (bias, organizational conflicts of interest) - Award to a non-responsible contractor - Improper sole-source determination

For vendors, protests are a defensive tool when an award goes wrong. They are not a primary business-development strategy — most agencies remember protesting vendors. File protests when you have strong factual grounds; do not file frivolous protests as a delay tactic.
