Bid Protest

A formal challenge by a losing bidder who believes a contract was awarded improperly — filed with the GAO, the Court of Federal Claims, or the contracting agency.

How It Works

Bid protests allow losing companies to challenge contract award decisions. The most common venue is GAO, which must issue a decision within 100 days. If GAO sustains a protest, it recommends the agency reevaluate proposals or resolicit. About 15-20% of GAO protests are sustained. Protests can delay contract work by months — the agency typically stops work (a "stay") until the protest is resolved. While protests serve as an important accountability mechanism, critics argue they're sometimes used tactically to delay competitors. The protest system helps ensure fair competition and compliance with procurement rules.
