Yes, but only in very limited circumstances. Arbitration decisions are designed to be final and binding. The Federal Arbitration Act (FAA) under Section 10 provides only four narrow grounds for a court to vacate (overturn) an arbitration award—and none of them allow you to challenge the arbitrator’s reasoning, interpretation of evidence, or application of the law simply because you disagree with the outcome.
According to research from the Virginia Journal of International Law, U.S. federal courts vacate or deny confirmation of only 3.3% to 5.7% of arbitration awards that are challenged. This statistic reveals a hard truth: the deck is stacked against parties seeking to overturn an arbitration decision.

Understanding the Federal Arbitration Act’s Limited Grounds for Vacatur
The Federal Arbitration Act governs most arbitration agreements in the United States. When you sign an arbitration agreement—whether for a credit card, employment contract, or business deal—you are agreeing to resolve disputes outside the court system. You also give up most of your appeal rights in exchange for a faster, private resolution.
Section 10 of the FAA lists the only four grounds a federal court may use to vacate an arbitration award:
| Ground for Vacatur | What It Means | Example |
|---|---|---|
| Corruption, fraud, or undue means | A party cheated during the arbitration process | A witness committed perjury that wasn’t discovered until after the award |
| Evident partiality or corruption in the arbitrator | The arbitrator was biased or had an undisclosed conflict of interest | Arbitrator failed to disclose a prior attorney-client relationship with opposing counsel |
| Arbitrator misconduct | The arbitrator refused to postpone a hearing for good cause or refused to hear material evidence | Arbitrator denied a request for continuance when a key witness was hospitalized |
| Arbitrator exceeded powers | The arbitrator went beyond the scope of the arbitration agreement or failed to render a definite award | Arbitrator awarded damages not permitted under the contract |
The U.S. Supreme Court made clear in Hall Street Associates v. Mattel (2008) that these four grounds are exclusive—parties cannot expand judicial review by contract agreement. This landmark decision shut the door on parties who hoped to include provisions in their arbitration agreements allowing courts to review the arbitrator’s legal conclusions.
The Three-Month Deadline: Miss It and Lose Your Right to Challenge
Under 9 U.S.C. § 12, you must serve notice of a motion to vacate on the opposing party within three months after the award is filed or delivered. This deadline is strictly enforced. Courts have repeatedly denied motions to vacate that were filed even one day late.
Consider this scenario: Maria receives an unfavorable arbitration award on January 15. She believes the arbitrator misapplied the law but wants to consult with several attorneys before deciding whether to challenge it. By the time she retains counsel and files her motion on April 20, she has missed the deadline. The court must deny her motion—regardless of how strong her arguments might have been.
The “Manifest Disregard of the Law” Doctrine: A Fading Lifeline
Before Hall Street, federal courts recognized an additional ground for vacatur called “manifest disregard of the law.” This allowed courts to overturn awards when an arbitrator knew about a governing legal principle but willfully ignored it.
After Hall Street, the federal circuits have split on whether this doctrine survives:
| Circuit | Position on Manifest Disregard |
|---|---|
| Second Circuit | Recognizes it as a “gloss” on Section 10(a)(4) |
| Fifth Circuit | Explicitly rejected manifest disregard as a valid ground |
| Ninth Circuit | Recognizes limited form for manifest disregard of facts |
| Eleventh Circuit | Rejected judicially-created grounds after Hall Street |
To succeed on a manifest disregard claim where it is still recognized, you must prove that the arbitrator: (1) knew of a governing legal principle, (2) understood it controlled the disputed issue, and (3) “willfully flouted” the law by refusing to apply it. The law you claim was ignored must be “well defined, explicit, and clearly applicable.”
This is an extremely high burden to meet. Courts will not vacate an award simply because the arbitrator made an error—even a serious error. The arbitrator must have essentially thumbed their nose at clearly established law.
Ground #1: Fraud, Corruption, or Undue Means
The first ground for vacatur focuses on party misconduct rather than arbitrator misconduct. To succeed, you must prove three elements:
- The fraud was material to the arbitration outcome
- The fraud was not discoverable through reasonable diligence before or during the arbitration
- Clear and convincing evidence establishes the fraud
Real Example: In Bernstein v. France, an NFL agent named Todd France committed fraud during arbitration by denying possession of documents and involvement in a disputed autograph event. His lies were not discovered until after the arbitrator ruled in his favor. The Third Circuit vacated the award because France’s fraud “procured” the decision—the lies directly impacted the case’s outcome and could not have been discovered earlier.
Scenario: When Fraud Claims Fail
| Situation | Outcome |
|---|---|
| Witness commits perjury, but arbitrator’s decision explicitly states witness testimony was not considered | Vacatur denied—no material connection between fraud and award |
| Party discovers opposing party made misrepresentations, but this was known during the arbitration | Vacatur denied—fraud was discoverable with due diligence |
| Party suspects fraud but offers only speculation without documentary evidence | Vacatur denied—must prove fraud by clear and convincing evidence |
Ground #2: Evident Partiality or Corruption of the Arbitrator
This ground addresses situations where the arbitrator had a conflict of interest or bias that was not properly disclosed. The focus is on protecting the integrity of the arbitrator selection process—parties must be able to choose their arbitrators intelligently.
Federal courts distinguish between two types of evident partiality cases:
Nondisclosure Cases: The arbitrator failed to reveal a fact that might indicate bias. You do not need to prove actual bias—only that the nondisclosure created a reasonable impression of partiality.
Actual Bias Cases: You are claiming the arbitrator was actually biased in decision-making. This requires a much higher showing—the “appearance of impropriety” alone is not enough.
Real Example: In Equicare Health Inc. v. Varian Medical Systems, an arbitrator named Mark Dosker answered “NO” to all conflict-of-interest questions—including whether he had any prior attorney-client relationship with a lawyer in the case. In fact, opposing counsel had represented Dosker’s law firm in a malpractice suit five years earlier. The court vacated the award because Dosker’s failure to disclose this relationship—and his failure to investigate—created a “reasonable impression of partiality.”
What Arbitrators Must Disclose
Arbitrators have an independent duty to investigate potential conflicts before accepting an appointment. Under most arbitration rules (including AAA and JAMS), arbitrators must disclose:
- Prior relationships with parties or their attorneys
- Financial interests in the outcome
- Other pending cases involving the same parties
- Personal relationships that might affect impartiality
Ground #3: Arbitrator Misconduct
Section 10(a)(3) allows vacatur when the arbitrator was guilty of misconduct that prejudiced a party’s rights. This includes:
- Refusing to postpone a hearing when good cause is shown
- Refusing to hear evidence that is pertinent and material
- Other “misbehavior” that prejudices a party
Critical Point: Unlike evident partiality, misconduct requires proof of prejudice. You must show the arbitrator’s actions actually harmed your case—not merely that the arbitrator made procedural errors.
Scenario: Medical Emergency Continuance
David requests a two-week continuance because his key expert witness had emergency surgery. The arbitrator denies the request, and David loses. Can he vacate the award?
| Factor | Analysis |
|---|---|
| Was the request for good cause? | Yes—medical emergency is valid cause |
| Did David provide documentation? | If yes, stronger case for vacatur |
| Was the evidence “pertinent and material”? | Expert testimony may be critical |
| Was David prejudiced? | Must show outcome would likely differ |
Courts rarely vacate awards for refusing to hear evidence because parties struggle to prove prejudice. Arbitrators have broad discretion over evidentiary matters, and courts defer to that discretion.
Ground #4: Arbitrator Exceeded Powers
This ground applies when the arbitrator went beyond the scope of authority granted by the arbitration agreement or failed to render a final, definite award. Courts analyze whether the arbitrator “strayed from interpretation and application of the agreement” and substituted their “own brand of industrial justice.”
Ways an Arbitrator Can Exceed Powers:
- Awarding relief not permitted under the contract
- Deciding issues not submitted for arbitration
- Failing to provide a “reasoned award” when the agreement required one
- Adding new contract terms not agreed to by the parties
Real Example: In a Florida maritime dispute, parties agreed in their contract that the arbitration panel would issue a “reasoned award“—one that explained the basis for its decision. Instead, the panel issued a two-page document that “simply announced the winners and losers” without any explanation. The court vacated the award because the arbitrators exceeded their powers by not complying with contractual requirements.
State Law Variations: California, New York, Texas, and Florida
State arbitration laws often mirror the FAA but contain important differences. The applicable law depends on whether your arbitration agreement is governed by state or federal law—and whether it involves interstate commerce.
California
The California Arbitration Act (CAA) under Code of Civil Procedure § 1286.2 provides grounds for vacatur similar to the FAA but adds important nuances:
California-Specific Ground: An award must be vacated if the arbitrator failed to disclose a ground for disqualification of which they were aware within the required time. California has strict arbitrator disclosure requirements under its Ethics Standards for Neutral Arbitrators.
Expanded Judicial Review: Unlike federal courts after Hall Street, California courts have held that parties can contractually agree to expand judicial review of arbitration awards under the CAA. This option is not available under the FAA.
Timeline: Petitions to vacate must be filed between 10 and 100 days after service of the award.
New York
New York’s arbitration law under CPLR Article 75 provides similar grounds for vacatur. Under CPLR 7511(b), awards may be vacated for:
- Corruption, fraud, or misconduct in procuring the award
- Partiality of an arbitrator appointed as neutral
- Arbitrator exceeding power or imperfectly executing it
- Failure to follow statutory arbitration procedures
New York Courts: Have interpreted the “irrational” or “completely irrational” standard as an additional basis for vacatur—when an award makes no sense whatsoever.
Timeline: Applications to vacate must be filed within 90 days of delivery of the award.
Texas
The Texas Arbitration Act (TAA) provides grounds similar to the FAA under Texas Civil Practice & Remedies Code § 171.088. The Texas Supreme Court has definitively ruled that:
Manifest disregard is NOT a valid ground for vacatur under the TAA. In Hoskins v. Hoskins, the court held that the TAA’s enumerated grounds are exclusive—courts cannot add common-law grounds.
Expanded Review by Agreement: Unlike federal law, Texas allows parties to contractually agree to expand judicial review. In Nafta Traders v. Quinn, the Texas Supreme Court held that parties can limit arbitrator authority by prohibiting “reversible error.”
Timeline: Motions to vacate must be filed within 90 days of delivery of the award.
Florida
The Florida Arbitration Code under F.S. § 682.13 provides grounds for vacatur and adds one unique provision not found in the FAA:
Florida-Specific Ground: An award may be vacated if the challenging party was not properly notified of the arbitration’s initiation and suffered substantial prejudice from lack of notice.
No Expanded Review: Florida courts have held that the FAC’s grounds cannot be supplemented judicially or contractually.
Special Context: FINRA Securities Arbitration
Financial Industry Regulatory Authority (FINRA) arbitration handles disputes between investors and brokerage firms. FINRA does not have an internal appeals process—you cannot appeal a FINRA award to FINRA itself.
However, you can challenge a FINRA award in federal or state court using the same FAA grounds discussed above. The challenge must be filed within three months of receiving the award.
Why FINRA Awards Are Difficult to Overturn:
FINRA arbitrators often do not issue “reasoned awards” explaining their decisions unless specifically requested. Without knowing the arbitrator’s reasoning, it is nearly impossible to prove “manifest disregard of the law” or that the arbitrator exceeded powers.
| FINRA Award Type | Typical Content | Challenge Difficulty |
|---|---|---|
| Standard Award | Lists parties, claims, and damages awarded—no reasoning | Very difficult to challenge |
| Reasoned Award | Includes explanation of how damages were calculated | Somewhat easier to identify errors |
| Explained Decision | Detailed factual findings and legal conclusions | Best chance to identify grounds for vacatur |
Tip: If you are initiating FINRA arbitration, request an explained decision from the outset. This costs more but creates a record that might support a later challenge if needed.
Private Appellate Arbitration: AAA and JAMS Options
The American Arbitration Association (AAA) and JAMS offer Optional Appellate Arbitration Rules that provide a true appeal within the arbitration system—not just the limited judicial review available in courts.
AAA Optional Appellate Rules
Under AAA’s rules, parties who agree to appellate review can appeal on grounds that the underlying award:
- Contains errors of law that are material and prejudicial
- Is based on factual determinations that are “clearly erroneous”
Key Features:
| Feature | AAA Appellate Rules |
|---|---|
| Time to Appeal | 30 days from receipt of underlying award |
| Appeal Panel | Typically three arbitrators with appellate experience |
| Briefing | Opening briefs limited to encourage conciseness |
| Decision Timeline | Approximately 3 months |
| Standard of Review | Broader than courts—reviews for legal and factual error |
Critical Requirement: Parties must agree in advance to use the appellate rules—either in the original arbitration agreement or by stipulation during arbitration. A losing party cannot unilaterally invoke these rules after receiving an unfavorable award.
JAMS Optional Appeal Procedure
JAMS has offered appellate procedures since 2003. The JAMS appeal panel applies the same standard of review that a first-level appellate court would apply to a trial court decision—meaning it can reverse for legal error or clearly erroneous factual findings.
| Feature | JAMS Appeal Procedure |
|---|---|
| Time to Appeal | 14 calendar days after award becomes final |
| Appeal Panel | Three JAMS neutrals (or one by agreement) |
| Oral Argument | Available if all parties request it |
| Decision Timeline | 21-30 days after final submissions |
| Final Award | Panel decision becomes final award for judicial confirmation |
When to Consider Private Appeals:
Private appellate arbitration makes sense for:
- High-stakes commercial disputes where the accuracy of legal conclusions is critical
- Complex cases involving contested issues of law or fact
- Situations where both parties want finality but also want protection against serious error
Employment Arbitration Challenges
Employment arbitration presents unique challenges for workers. Many employees are required to sign arbitration agreements as a condition of employment, often without understanding they are waiving their right to a jury trial and meaningful appellate review.
Key Concerns in Employment Arbitration
Limited Appeals: Arbitrator decisions are final with few options for appeal, even if the ruling appears flawed.
Potential Bias: Employers may repeatedly use the same arbitrators, creating a perception (or reality) of pro-employer bias.
Class Action Waivers: Many employment arbitration agreements prohibit class or collective actions, making it economically impractical to pursue small individual claims.
Scenario: Sarah’s Overtime Claim
Sarah believes her employer owes her $3,000 in unpaid overtime. Her employment agreement requires individual arbitration. The arbitration filing fee is $300, and she must share the arbitrator’s hourly rate. Even if she wins, the award may not cover her costs—and she has no practical right to appeal an adverse decision.
| Factor | Impact |
|---|---|
| Individual claim value | $3,000 |
| Arbitration costs | $300+ filing fee, shared arbitrator fees |
| Attorney fees | Often exceeds claim value |
| Appeal rights | Limited to FAA grounds (nearly impossible to meet) |
| Practical outcome | Many claims are never pursued |
Three Common Scenarios: When Challenges Succeed and Fail
Scenario 1: The Biased Arbitrator (Success)
Facts: A homeowner named Patricia goes through arbitration with a major bank over a credit card dispute. After losing, she discovers that the arbitrator had served as a “dispute resolution neutral” in four other matters involving the bank’s law firm—and received offers to serve as a neutral in additional matters. The arbitrator did not disclose these ongoing relationships.
| Action | Consequence |
|---|---|
| Arbitrator fails to disclose prior relationships with counsel | Creates reasonable impression of partiality |
| Patricia files motion to vacate within deadline | Court considers the petition |
| Patricia proves arbitrator’s disclosure obligations were violated | Award vacated under “evident partiality” |
| Case remanded for new arbitration before different arbitrator | Patricia gets second chance |
Scenario 2: Disagreement with Outcome (Failure)
Facts: Tom arbitrates a business dispute and receives an award requiring him to pay $500,000. He believes the arbitrator misinterpreted the contract and applied the wrong legal standard. He files a motion to vacate, arguing the arbitrator made legal errors.
| Action | Consequence |
|---|---|
| Tom disagrees with arbitrator’s legal reasoning | Not a valid ground for vacatur |
| Tom argues arbitrator “got it wrong” | Courts do not review merits of arbitration |
| Motion to vacate denied | Tom must pay the $500,000 award |
| Tom learns arbitration awards are essentially unreviewable | Lesson: litigation may be preferable for some disputes |
Scenario 3: Missed Deadline (Failure)
Facts: Jennifer receives an arbitration award on March 1. She consults three attorneys, debates whether to challenge it, and finally files a motion to vacate on June 5—four days past the three-month deadline under the FAA.
| Action | Consequence |
|---|---|
| Award delivered March 1 | Three-month deadline begins running |
| Jennifer delays filing until June 5 | Deadline expired June 1 |
| Court dismisses motion as untimely | No exceptions for “good reasons” to delay |
| Jennifer loses right to challenge award | Even potentially valid grounds are barred |
Mistakes to Avoid When Challenging an Arbitration Award
1. Missing the Deadline
The three-month (federal) or 90-day (most states) deadline is strictly enforced. Courts do not make exceptions for good faith delays, complexity of the case, or difficulty finding an attorney. Calendar the deadline immediately upon receiving the award.
2. Failing to Preserve Objections During Arbitration
If you fail to object to arbitrator misconduct, bias, or procedural errors during the arbitration, you may waive your right to raise those issues later. Document all objections on the record.
3. Challenging the Merits Instead of the Process
Courts will not vacate an award because the arbitrator “got it wrong” on the facts or law. Focus your challenge on process failures—fraud, arbitrator bias, misconduct, or exceeding powers—not on why you should have won.
4. Failing to Research the Arbitrator
Before agreeing to an arbitrator, conduct thorough research on their background, prior awards, and potential conflicts. Challenging bias after losing is much harder than preventing it.
5. Assuming “Manifest Disregard” Still Works
In many federal circuits, manifest disregard of the law is no longer a valid ground for vacatur. Research your circuit’s position before relying on this argument.
Do’s and Don’ts for Challenging Arbitration Awards
Do’s
| Do | Why |
|---|---|
| File your motion to vacate immediately after deciding to challenge | Protects against missing the strict deadline |
| Hire an attorney experienced in arbitration appeals | These cases require specialized knowledge of limited grounds |
| Preserve objections during the arbitration itself | Waiver is a common defense against challenges |
| Request a “reasoned” or “explained” award | Creates record that might reveal grounds for vacatur |
| Investigate arbitrator background before appointment | Prevents bias issues from arising |
Don’ts
| Don’t | Why |
|---|---|
| Wait to see if the other side will “work something out” | Deadline runs regardless of negotiations |
| File a motion based solely on disagreement with outcome | Courts will deny it and you may face sanctions |
| Assume you can expand judicial review by contract | Under the FAA, you cannot (state law may differ) |
| Ignore disclosure deficiencies during arbitration | Failure to object may constitute waiver |
| Represent yourself in complex vacatur motions | The legal standards are highly technical |
Pros and Cons of Arbitration’s Limited Appeal Rights
Pros of Limited Appeals
| Pro | Explanation |
|---|---|
| Finality | Disputes end quickly without years of appellate litigation |
| Lower costs | Avoiding appeals reduces total legal expenses |
| Efficiency | Resources are not consumed by multiple levels of review |
| Certainty | Parties can plan based on a final decision |
| Confidentiality preserved | Appeals would create public court records |
Cons of Limited Appeals
| Con | Explanation |
|---|---|
| Uncorrectable errors | Even serious mistakes go unremedied |
| Arbitrator accountability | Little consequence for poor decisions |
| Power imbalance | Repeat players (corporations) may benefit from familiarity with arbitrators |
| Loss of legal development | No precedent created to guide future cases |
| Unpredictability | Arbitrators not bound by rules of evidence or procedure |
The Confirmation Process: What Happens If You Don’t Challenge
If you do not file a motion to vacate within the deadline, the winning party will likely file a petition to confirm the arbitration award. Once confirmed, the award becomes a court judgment that can be enforced through:
- Wage garnishment
- Bank account levies
- Property liens
- Contempt proceedings
Under the FAA, petitions to confirm must be filed within one year after the award is made. Courts are required to confirm awards unless a valid ground for vacatur is established—which happens in only a small percentage of cases.

FAQs
Can I appeal an arbitration decision if I think the arbitrator made a legal mistake?
No. Legal error alone is not a ground for vacatur under the FAA. You must prove the arbitrator exceeded powers, was biased, committed misconduct, or the award was procured by fraud.
How long do I have to challenge an arbitration award?
Three months under federal law (9 U.S.C. § 12) or 90-100 days under most state laws. Missing this deadline bars your challenge entirely.
Can I agree in my contract to have broader court review of arbitration awards?
No under the FAA, but yes in some states. Texas and California allow contractual expansion of judicial review under state arbitration acts.
Does FINRA have an appeals process for arbitration awards?
No. FINRA does not hear appeals. However, you can challenge FINRA awards in federal or state court using FAA grounds.
What percentage of arbitration awards are successfully vacated?
Very few. Studies show courts vacate only 3-10% of challenged awards, depending on the jurisdiction and type of arbitration.
Can I appeal through AAA or JAMS instead of going to court?
Yes, but only if both parties agreed to appellate rules. AAA and JAMS offer optional appellate procedures with broader standards of review than courts provide.
What is “evident partiality” and how do I prove it?
Evident partiality occurs when an arbitrator has an undisclosed conflict of interest. You must prove the nondisclosure created a “reasonable impression of partiality“—you do not need to prove actual bias.
Is “manifest disregard of the law” still a valid ground to challenge an award?
It depends on your circuit. The Fifth Circuit explicitly rejected it, while the Second Circuit still recognizes it in limited form.
Can I challenge an arbitration award if the arbitrator refused to postpone a hearing?
Possibly. You must prove the refusal was misconduct, you had sufficient cause for postponement, and the refusal prejudiced your rights. Courts rarely grant vacatur on this ground.
What happens if I don’t challenge the award within the deadline?
You lose your right to challenge it. The winning party will petition to confirm the award, which becomes an enforceable court judgment.
Can I sue the arbitrator for making a bad decision?
No. Arbitrators have quasi-judicial immunity and cannot be sued for their decisions, even if those decisions were wrong.
Should I request a “reasoned award” in arbitration?
Yes. A reasoned award explains the arbitrator’s decision-making process, which helps you evaluate whether grounds for vacatur exist and supports any challenge you file.
