FAR Part 33 — Protests, Disputes, and Appeals

What this Part does

Part 33 governs two very different things that get confused because they’re in the same Part:

  1. Protests (Subpart 33.1) — challenges to the award process. Filed by an offeror or prospective offeror arguing the agency violated procurement law or the solicitation’s own terms. Three fora: agency-level, GAO (General Accountability Office — the big one), and Court of Federal Claims (COFC — for judicial review with different standing and remedies rules).
  2. Disputes (Subpart 33.2) — challenges to the performance of an awarded contract. Filed by the contractor (or, rarely, the government) under the Contract Disputes Act (41 USC 7101 et seq.). Moves from the Contracting Officer’s final decision to either an agency Board of Contract Appeals (ASBCA for defense, CBCA for civilian) or to COFC directly.

Protests and disputes have different triggers, different timelines, different standards of review, and different remedies. Confusing them is the single biggest unforced error in federal contracting litigation.

When you’d look here

  • Your client was not selected for award and has reason to believe the evaluation violated the RFP’s own terms (FAR 33.103–FAR 33.104).
  • You need to know the 10-day debriefing clock for GAO protest timing (with DoD “enhanced debriefing” shifting under DFARS 215.506).
  • A contracting officer issued a final decision on a claim and your client needs to decide between ASBCA/CBCA (informal, administrative) vs. COFC (formal, judicial).
  • The agency issued a stop-work notice or a change order that’s costing money, and you need to convert that into a certified claim under FAR 33.207.
  • The statute of limitations clock is running on a dispute (FAR 33.206 — 6 years under the CDA, with narrow tolling).
  • Your client is being sued by a subcontractor who wants to flow a claim through the prime (sponsorship).

Case study: the protest timing trap

Atlas Logistics, an unsuccessful offeror on a DLA subsistence contract, received a pre-award notice of unsuccessful offeror (FAR 15.503(a)) on a Tuesday morning. The notice was terse: Atlas was not in the competitive range. Atlas’s business development lead, not a procurement specialist, filed an agency-level protest the following Monday — 6 calendar days later — under FAR 33.103.

Here’s the problem. Agency-level protests stop the clock on that forum, but they don’t automatically preserve GAO rights. If the agency denies the protest (and agencies nearly always do), Atlas has another 10 calendar days from the denial to go to GAO — but only if the original protest to the agency was filed timely under GAO’s timeliness rules, not the agency’s.

Atlas assumed it could file at GAO after the agency denial, because the agency had accepted the protest as timely. It couldn’t. GAO’s timeliness rule (4 CFR 21.2(a)(2)) requires a pre-award protest challenging exclusion from the competitive range to be filed within 10 calendar days of when the basis was “known or should have been known” — counted from the original Tuesday notice, not the agency denial. Atlas had 10 days from Tuesday. It waited until after the agency denied the protest; by then, the GAO window had run.

GAO dismissed as untimely. Atlas filed at COFC as a last resort, but COFC standard of review under the Administrative Procedure Act (arbitrary-and-capricious) is deferential to agencies, and without the factual record GAO would have developed, the COFC case was thin. Atlas lost on summary judgment.

Teaching points:

  1. Agency-level protests do NOT extend GAO’s clock. If you file agency first, you must also file GAO within the original GAO deadline, not GAO’s deadline from the agency’s denial.
  2. The debriefing clock for post-award protests is famously fraught: FAR 33.104 + FAR 15.506 set the 5-day window for an enhanced debriefing (DoD) and 10 days from debriefing closing to file at GAO. For a CICA automatic stay, the post-award protest must be filed within 5 days of debriefing closing or 10 days of award, whichever is later.
  3. Protest forums are not stacked the way appeals courts are. You don’t “appeal” from GAO to COFC; they’re parallel forums with different rules. Picking correctly on day 1 is the entire game.

Case study: converting a dispute into a CDA claim

Vega Shipyard (hypothetical) was mid-performance on a 230K of material, accumulated over three months. Vega’s team kept doing the work and sent routine monthly progress invoices. No separate REA (Request for Equitable Adjustment) was filed. No certified claim under FAR 33.207 was submitted.

Nine months after delivery and final payment, Vega realized the changes had never been bilaterally modified into the contract price. Vega’s counsel prepared a claim for the 100,000** must be certified by a person duly authorized to bind the contractor. Vega’s claim was certified.

The CO denied the claim on the merits: the COR didn’t have authority to direct changes outside the scope of the existing contract clauses, and the Changes clause (FAR 52.243-1) required notice within 30 days of the COR’s direction to preserve an equitable adjustment right. Vega hadn’t given that notice.

Vega appealed to the ASBCA. The Board found (a) the COR did have authority to direct the work because the work fell within the “general scope” of the Changes clause, but (b) Vega’s failure to provide 30-day written notice under FAR 52.243-1(c) did waive the equitable adjustment right for changes more than 30 days before the notice. Vega recovered about 40% of the claim — the portion within the 30-day window and a small “constructive change” carve-out for the most recent items.

Teaching points:

  1. Don’t sit on changes. The Changes clause’s 30-day notice rule is real and routinely enforced. File an REA quickly even if it’s rough, then refine.
  2. Certify the claim. Unless the dollar amount is genuinely below $100K, certification is mandatory for CDA jurisdiction. Defective certifications are curable; missing certifications are not, and can be fatal at the Board or COFC.
  3. A dispute is not a protest. If Vega had tried to protest this at GAO, GAO would have dismissed immediately — no jurisdiction over contract administration disputes.
