Contract Disputes Act (CDA)

The Contract Disputes Act of 1978 is the federal law that governs how disputes between the government and its contractors are resolved — from a $500 disagreement over a supply order to a multibillion-dollar defense contract claim governed by the Federal Acquisition Regulation. The CDA establishes a structured process: the contractor submits a claim to the contracting officer, who issues a written decision; the contractor may then appeal to an agency board of contract appeals or the U.S. Court of Federal Claims; and final appeals go to the U.S. Court of Appeals for the Federal Circuit. This system handles thousands of disputes annually, totaling billions of dollars.

Current Law (2026)

Legal Authority

• 41 U.S.C. § 7102 — Applicability (CDA applies to any express or implied contract made by an executive agency for procurement of property or services, construction, and related activities)
• 41 U.S.C. § 7103 — Decision by contracting officer (each contractor claim must be submitted in writing to the CO; claims over $100,000 require certification that the claim is made in good faith, supporting data are accurate, and the amount reflects the contract entitlement believed to be due; CO must issue a written decision with reasons)
• 41 U.S.C. § 7104 — Contractor's right of appeal (contractor may appeal CO's decision to an agency board within 90 days, or bring an action in the Court of Federal Claims within 12 months)
• 41 U.S.C. § 7105 — Agency boards (Armed Services Board of Contract Appeals and Civilian Board of Contract Appeals; boards composed of administrative judges with full authority to decide contract disputes)
• 41 U.S.C. § 7106 — Small and accelerated claims (disputes ≤$50,000: simplified small claims procedure; disputes ≤$100,000: accelerated procedure with 180-day decision requirement)
• 41 U.S.C. § 7107 — Judicial review (board decisions appealable to the Federal Circuit within 120 days; Court of Federal Claims decisions appealable to the Federal Circuit)
• 41 U.S.C. § 7109 — Interest (interest on amounts found due to the contractor runs from the date the CO receives the claim until payment)

How It Works

The CDA creates a tiered dispute resolution system. At the first level, the contracting officer (the government official administering the contract) reviews the claim and issues a decision. The CO decision is a binding determination unless appealed — if the contractor doesn't appeal within the deadline, the decision is final.

Claims over $100,000 require the contractor to certify — under penalty of law — that the claim is made in good faith, that supporting data are accurate and complete, and that the amount reflects what the contractor believes is due under the contract. False certification can result in forfeiture of the claim and referral for prosecution under the False Claims Act.

The contractor has two appeal options: an agency board of contract appeals (filed within 90 days of the CO decision) or the U.S. Court of Federal Claims (filed within 12 months). The boards — primarily the Armed Services Board of Contract Appeals (ASBCA) for defense contracts and the Civilian Board of Contract Appeals (CBCA) for civilian agency contracts — are composed of administrative judges who conduct trial-type proceedings and issue written decisions.

Small claims (≤$50,000) and accelerated claims (≤$100,000) have streamlined procedures designed for speed and simplicity. Small claims proceedings are informal and produce decisions within 120 days. Accelerated proceedings have a 180-day decision requirement. These procedures make the dispute resolution system accessible to small contractors who can't afford extended litigation.

Interest runs from the date the CO receives the claim — not from the date of the dispute or the date of the decision. This creates a financial incentive for the government to resolve claims promptly and compensates contractors for the time value of money during the dispute process.

Judicial review of board decisions goes to the U.S. Court of Appeals for the Federal Circuit, which also hears appeals from the Court of Federal Claims. The Federal Circuit applies different standards of review depending on the forum below — substantial evidence review for board factual findings, de novo review for Court of Federal Claims findings. This creates a unified appellate body for government contract disputes.

Implementing Regulations

• 48 CFR Part 1 — Federal Acquisition Regulation (§§ 1.602, 1.603 — contracting officer authority, selection, appointment, and termination)

• 48 CFR Part 33, Subpart 33.2 — FAR Contract Disputes (the regulatory implementation of the Contract Disputes Act (41 U.S.C. ch. 71) — claim submission, contracting officer decision, interest, and ADR):

  • § 33.201 — Definitions: "claim" means a written demand by the contractor or government seeking a decision on a matter in controversy — routine requests for payment are not "claims" until disputed; "accrual" is the key timeliness concept — the 6-year statute of limitations runs from the date when all events fixing liability were known or should have been known
  • § 33.206 — Claim submission: contractor claims must be submitted in writing to the contracting officer within 6 years of accrual; the 6-year limit applies to contracts awarded after October 1, 1995; claims may be for money, property, or interpretation of contract terms; a claim does not need to use the word "claim" but must be a clear, unequivocal written demand seeking a final decision
  • § 33.207 — Contractor certification: any contractor claim exceeding $100,000 must be certified — the contractor must certify that the claim is made in good faith, the supporting data are accurate and complete, the amount accurately reflects the contract adjustment sought, and the certifier is authorized to bind the contractor; uncertified claims over $100,000 are defective and the CO may withhold a final decision until corrected; knowingly submitting a false certification is a False Claims Act violation
  • § 33.208 — Interest: the government pays interest on contractor claims at the Treasury Rate (set each January and July) from the date the CO receives the certified claim (or the date payment was due, if earlier) until payment; interest does not run on government claims against the contractor
  • § 33.210 — Contracting officer authority: the CO has full authority to decide or settle any claim arising under the contract — no higher-level approval is required to issue a final decision; the CO should document the rationale clearly because the final decision is the baseline for any board or court appeal
  • § 33.211 — Final decision: when a claim cannot be resolved by mutual agreement, the CO must issue a written final decision; for claims ≤ $100,000, the CO must decide within 60 days; for larger claims, the CO must either decide or notify the contractor of a reasonable time for decision within 60 days; the final decision must inform the contractor of its appeal rights (ASBCA/CBCA within 90 days, COFC within 12 months); failure to issue a final decision within a reasonable time permits the contractor to "deem" the claim denied and appeal immediately
  • § 33.213 — Obligation to continue performance: during any dispute, the contractor must continue performance and the government must continue paying undisputed amounts; stopping work during a pending dispute — unless the contract is terminated — breaches the contract and exposes the contractor to default termination consequences; this "keep the wheels turning" rule prevents disputes from halting critical government programs while litigation proceeds
  • § 33.214 — Alternative dispute resolution (ADR): the CO must actively consider ADR before issuing a final decision on any claim; ADR options include neutral evaluation, minitrials, mediation, and arbitration; boards of contract appeals (CBCA, ASBCA) operate formal ADR programs and encourage settlement at every stage; ADR resolved approximately 30–35% of CBCA cases before formal decision in recent years

  The claim-to-final-decision pipeline under FAR 33.2 is the mandatory first step before any board or court appeal. No CBCA or ASBCA jurisdiction exists unless the contractor first submitted a written claim to the CO and received (or was deemed to have received) a final decision. No major amendments since 76 FR 14560 (March 2011) — clarified the definition of "claim" to exclude routine contract administration requests.

• 48 CFR Part 1233 — DOT acquisition regulation (§§ 1233.211, 1233.212 — contracting officer's decision, duties upon appeals)

• 41 CFR Part 105-53 — GSA organization (§ 105-53.132 — Civilian Board of Contract Appeals)

• 48 CFR Part 6101 — Rules of Procedure of the Civilian Board of Contract Appeals (CBCA) — the complete procedural rulebook for the CBCA, which adjudicates all CDA appeals from civilian executive-branch agencies (approximately 30 agencies including the Departments of State, Interior, Agriculture, Transportation, Commerce, and Energy, as well as independent agencies and the Postal Service; excludes DOD disputes, which go to the ASBCA, and legislative branch disputes, which go to the GAO CAB). The CBCA is an independent tribunal within GSA — its judges are appointed for 5-year renewable terms and are subject to removal only for cause. Key procedural rules:

  • Rule 1 (§ 6101.1) — Scope and jurisdiction: the CBCA has jurisdiction over CDA appeals from final decisions of contracting officers in covered civilian agencies; appeals must be filed within 90 days of receiving the contracting officer's final decision (or within 12 months to file in the Court of Federal Claims as an alternative forum — the two forums are exclusive once chosen); a timely notice of appeal is jurisdictional — missing the 90-day deadline permanently bars CBCA review and leaves only Court of Federal Claims jurisdiction
  • Rule 2 (§ 6101.2) — Filing: the notice of appeal must be (a) in writing; (b) signed by the contractor or its counsel; (c) state the contract number and the name/address of the contracting agency; and (d) identify what is being appealed; formal legal pleadings are not required for the initial filing — the Board will develop the record through subsequent filings; the contractor files a complaint within 30 days of docketing, and the government files an answer within 30 days of the complaint
  • Rule 12 (§ 6101.12) — Stays and dismissals: the Board may stay cases while related litigation proceeds in other forums (federal courts, ASBCA); cases may be dismissed for lack of jurisdiction, failure to prosecute, or settlement; the Board tracks its own docket and sets expectations on timely case development
  • Rules 13–16 (§§ 6101.13–6101.16) — Discovery: the Board permits standard discovery — depositions, interrogatories, requests for production, requests for admission, and subpoenas; depositions may be taken at any time after the contractor files the complaint; the Board can impose sanctions for non-compliance with discovery orders including adverse inferences, evidence preclusion, and dismissal
  • Rule 18 (§ 6101.18) — Election of hearing or record submission: a party may elect to have its case heard at a hearing (oral testimony, live cross-examination) or submit it on the written record without a hearing; most complex cases go to hearing; the Board retains authority to require a hearing even if a party prefers record submission; hearings are typically held in Washington or at a location convenient to the parties
  • Accelerated Procedure: governed by 41 U.S.C. § 7106(a) — for claims ≤ $100,000, the contractor may elect accelerated processing; the Board aims to decide within 180 days of election; discovery is limited and focused on the dispositive issues
  • Small Claims Procedure: governed by 41 U.S.C. § 7106(b) — for claims ≤ $50,000 (or ≤ $150,000 if the contractor is a small business concern), the contractor may elect the expedited small claims procedure; the Board aims to decide within 120 days; limited discovery, case submitted largely on the record; the decision is final and not precedential <!-- FACTCHECK 2026-05-11: confirm CBCA rules don't extend these thresholds beyond statutory CDA limits — wiki-factcheck -->
  • Rule 29 (§ 6101.29) — CBCA decisions and finality: a CBCA final decision on the merits is subject to review by the Court of Appeals for the Federal Circuit — the specialized appellate court with exclusive jurisdiction over government contracts matters; the standard of review is de novo on legal questions and "substantial evidence" on factual findings; CBCA decisions are not binding precedent on other agencies' contracting officers (that role belongs to Court of Federal Claims and Federal Circuit decisions) but are persuasive authority and shape contracting practice

  The CBCA was created in 2007 when it replaced the separate boards of contract appeals at General Services Administration, the Department of Transportation, and other civilian agencies — consolidating what had been fragmented agency-specific forums into a single board. The board has roughly 20 Administrative Judges hearing hundreds of cases per year. Understanding the CBCA's jurisdiction is critical for contractors: government contract disputes escalate through a specific chain — informal resolution → contracting officer's final decision → Board of Contract Appeals (CBCA or ASBCA) or Court of Federal Claims — with strict deadlines at each stage; missing the CBCA appeal window doesn't end the dispute but eliminates the inexpensive administrative forum option.

  Recent rulemakings: 83 FR 41010 (2018) — significant rule revision updating case management procedures, increasing monetary thresholds for accelerated and small claims procedures, and adding electronic filing requirements. 91 FR 3789 / 3791 / 3792 (January 2026) — updated rules governing CBCA alternative dispute resolution programs and streamlined summary judgment procedures.

• 4 CFR Part 22 — Rules of Procedure of the Government Accountability Office Contract Appeals Board: the procedural rulebook for the GAO Board of Contract Appeals (GAO CAB), which hears contract disputes and bid protests arising from contracts with legislative branch agencies — the U.S. Senate, House of Representatives, Capitol Police, Library of Congress, Government Publishing Office, and other agencies of the legislative branch. The GAO CAB occupies a distinct niche in the government contracting dispute resolution system: the CBCA handles civilian executive-branch disputes, the ASBCA handles Defense Department disputes, and the GAO CAB handles legislative branch disputes. Key provisions:

  • § 22.1 (Rule 1) — Jurisdiction and applicability: the Board hears appeals when a contracting officer in a legislative branch agency issues a final decision on a contract claim; rules apply to any appeal filed on or after October 1, 2007 (the date the Board's current rules took effect)
  • § 22.8 (Rule 8) — Discovery and scheduling: discovery is governed by a scheduling order the Board issues after initial pleadings; the schedule sets separate deadlines for document production requests, interrogatories, depositions, and summary judgment motions; time limits can be extended for good cause but the Board controls the pace
  • § 22.10 (Rule 10) — Sanctions: the Board may sanction parties, attorneys, and experts for noncompliance with Board orders; sanctions range from treating disputed facts as established, barring evidence or claims, striking filings, or dismissing the appeal; attorneys face potential suspension from appearing before the Board after notice and opportunity to respond (majority-of-members vote required); the broad sanction authority reflects the Board's need to manage disputes efficiently without the full federal court infrastructure
  • § 22.11–22.14 (Rules 11–14) — Discovery tools: depositions (oral or written, any time after docketing and complaint filing, no fixed limit subject to Board restrictions), interrogatories (written questions to the opposing party, answers under oath, no fixed limit), requests for admission (treated as admitted if not timely denied), and document production requests (including electronically stored information); the Board may order inspection of land or property
  • § 22.19 (Rule 19) — Settlement: parties may settle at any time; settlements are final and binding; the Board closes the case upon notice of settlement without reviewing settlement terms unless a question of authority arises

  The GAO CAB's procedures closely track those of the CBCA and ASBCA — reflecting the CDA's intent to create a consistent dispute-resolution structure across the federal government — but its legislative branch jurisdiction makes it a specialized forum that sees fewer cases than the executive-branch boards. Contractors working on Capitol complex renovations, Congressional IT systems, Library of Congress digitization projects, and similar legislative-branch work should understand that disputes go to the GAO CAB rather than the CBCA.

• 39 CFR Part 955 — Rules of Practice Before the Postal Service Board of Contract Appeals (PSBCA) (30 sections — the procedural rulebook for the USPS-specific contract appeals board, which hears CDA appeals from contractors who performed contracts for the United States Postal Service). The PSBCA is one of the oldest agency boards of contract appeals, predating the CDA itself, and it has jurisdiction over all USPS construction, supplies, and services contracts — including delivery vehicle fleets, sortation facility construction, IT systems, and mail processing equipment. Its rules closely track the CBCA and ASBCA procedural framework. Key provisions:

  • Rule 1 (§ 955.1) — Jurisdiction and filing: the PSBCA has jurisdiction under the CDA over any appeal by a USPS contractor from a Contracting Officer's Final Decision (COFD); appeals must be filed in writing with the PSBCA within 90 days of receiving the COFD (or within 12 months to file in the Court of Federal Claims); the Board sits in Washington D.C. but may conduct hearings anywhere in the country; jurisdiction is established when the PSBCA receives the written appeal notice identifying the contract and the COFD being appealed
  • Rule 4 — Appeal file: after a notice of appeal is filed, the USPS Contracting Officer must submit the complete Rule 4 appeal file — the government's assembled record including the contract, modifications, correspondence, COFD, and supporting documents — within 30 days; the appeal file is the foundational record for all subsequent proceedings and is presumed complete unless a party demonstrates omissions
  • Rule 10 — Conferences: the Board may hold status conferences at any time to manage case progress, narrow issues, explore settlement, or discuss scheduling; the PSBCA actively manages its docket and will schedule conferences early in complex cases to identify the core disputed facts and legal theories before discovery begins
  • Rule 11 — Submission without hearing: either party may elect to submit the appeal on the written record without a live hearing; the Board sets a briefing schedule and decides the case on documents, declarations, and argument alone; most smaller or legal-question-only cases are resolved on the record
  • Rule 12 — Small Claims (Expedited) and Accelerated Procedures: tracking the CDA, for claims ≤ $50,000 (or ≤ $150,000 for small business concerns) the appellant may elect the expedited small claims track — the Board aims to decide within 120 days of election, discovery is limited, and the decision is final and non-precedential; for claims ≤ $100,000 (accelerated), the contractor may elect — the Board targets a 180-day decision timeline with focused discovery; both procedures preserve all appeal rights to the Court of Appeals for the Federal Circuit
  • Rule 14 — Discovery: the Board encourages voluntary discovery; either party may petition for depositions, interrogatories, requests for admission, and document production with Board approval; the Board issues protective orders to preserve confidentiality of proprietary information, pricing data, or trade secrets — critical given that USPS procurement data can reveal commercially sensitive supplier relationships
  • Rule 15 — Interrogatories, admissions, and document production: written discovery tools available post-docketing; the Board manages pace and scope to balance thorough fact-finding against efficiency; electronically stored information (ESI) is explicitly covered — parties must confer on ESI formats and preservation obligations early in the case
  • Rule 17 — Hearings: the Board sets time, place, and duration after consulting with parties; hearings may be held at PSBCA's hearing room or remotely; witnesses testify under oath and are subject to cross-examination; the hearing record is certified by the Board
  • Finality and appeal: PSBCA decisions are final on the merits subject to appeal to the Court of Appeals for the Federal Circuit on questions of law (de novo) and fact (substantial evidence); the PSBCA's decisions on common USPS contract types (vehicle fleet maintenance, mail processing equipment, sortation systems) constitute a body of specialized precedent that USPS contracting officers use in drafting and administering subsequent contracts

  The PSBCA handles a distinctive mix of disputes driven by USPS's unique procurement portfolio: billions in facility leases and construction (postal processing plants, delivery stations, the postal vehicle fleet); IT infrastructure for mail tracking and delivery confirmation; and specialized postal equipment that has no commercial equivalent. The PSBCA hears roughly 200-400 appeals annually. Unlike other agency boards, the PSBCA does not have jurisdiction over bid protests — USPS bid protests go to the USPS Judicial Officer or, if the contractor chooses, to the PSBCA only after a COFD. Contractors dealing with USPS disputes should note that USPS is not subject to the Competition in Contracting Act or the standard bid protest procedures applicable to other federal agencies; instead, USPS has its own procurement manual and protest procedures.

Recent Developments

The CDA dispute resolution system has adapted to modern contracting challenges. Cybersecurity contract disputes, software licensing disagreements, and performance-based contracting claims present novel issues for the boards. The CBCA and ASBCA have modernized their procedures, including electronic filing and virtual hearings. Claim volumes fluctuate with government spending cycles — large acquisition programs and disaster response contracts generate corresponding waves of disputes. The Federal Circuit continues to develop government contract law through its appellate decisions, maintaining its role as the specialized court for procurement disputes.
