Introduction: The Critical Significance of Arbitrator Challenges in Cross-Border Disputes
As the global marketplace evolves and the United Arab Emirates (UAE) deepens its trade and investment ties with the United States, arbitration has cemented its central role in resolving commercial disputes. However, the integrity of any arbitral proceeding hinges upon the impartiality and independence of its arbitrators. For UAE businesses, executives, and legal practitioners engaged in US-facing contracts, understanding the legal processes and grounds for challenging and removing arbitrators under US law is imperative—particularly as recent updates in UAE and international arbitration frameworks raise the bar for procedural rigor and party autonomy.
This article offers a comprehensive analysis of the mechanisms governing the challenge and removal of arbitrators under US law, with a focused lens on what this means for UAE companies, legal consultants, and HR managers handling cross-border agreements. Drawing on official sources and practical consultancy experience, we assess the rules, procedures, strategic considerations, and compliance perspectives that UAE stakeholders must master for effective dispute resolution in Emirati-American commercial dealings.

US Arbitration Law Foundations and Regulatory Sources
Federal Arbitration Act (FAA): The Cornerstone Framework
The Federal Arbitration Act (9 U.S.C. §§ 1-16, hereinafter “FAA”) governs the vast majority of commercial arbitrations in the United States. Passed in 1925 and amended occasionally, the FAA establishes both the enforceability of arbitration agreements and the limited grounds on which arbitral awards may be challenged or vacated. Crucially, the FAA sets boundaries on party autonomy vis-à-vis the challenge and removal of arbitrators, ensuring that due process and procedural fairness are safeguarded.
Major US Arbitration Rules
In addition to statutory baselines set by the FAA, leading US arbitral institutions—including the American Arbitration Association (AAA) and JAMS—publish institutional rules that prescribe additional processes for challenging and removing arbitrators. These rules often operate parallel to, but not in conflict with, federal law, affording parties more granular procedural controls.
Relevance for UAE Stakeholders
For UAE-based companies, it is common for cross-border agreements with US-based partners to incorporate either the FAA or rules of recognized US arbitral bodies by reference. Understanding both tiers of regulation is essential for risk mitigation when negotiating, drafting, and enforcing arbitration clauses.
Grounds for Challenging Arbitrators: Statutory and Practical Perspectives
Statutory Grounds Under the FAA
The FAA itself is relatively sparing in expressly enumerating grounds for challenging sitting arbitrators prior to a decision. However, Section 10 of the FAA (9 U.S.C. § 10) identifies situations where a court may vacate an arbitral award on the following bases:
- Evident partiality or corruption in the arbitrators: If there is clear evidence that an arbitrator harbored bias or accepted improper inducements.
- Misconduct prejudicing parties’ rights: If the arbitrator engages in misconduct—such as refusing to hear pertinent evidence—that undermines the fairness of proceedings.
- Exceeding powers: Where arbitrators act outside the scope of their authority as agreed in the arbitration clause.
It is notable that the FAA prescribes primarily post-award (after the decision) relief; however, these standards inform the procedures for pre-decision challenges under institutional rules and state law.
Institutional Rules: AAA and JAMS
| Rule | AAA Commercial Rules | JAMS Comprehensive Arbitration Rules |
|---|---|---|
| Disclosure | Rule 17(a): Arbitrators must disclose potential conflicts or circumstances raising doubts as to impartiality/independence. | Rule 15: Similar standard—disclosure of relationships, interests, or circumstances causing potential bias. |
| Challenge Grounds | Challenge allowed where impartiality/independence is justifiably doubted. | Grounds include lack of neutrality, undisclosed conflicts, or incapacity. |
| Decision Maker | The AAA administers the challenge; in some rules, chair of the tribunal may rule. | JAMS decides administratively unless parties agree otherwise. |
Both sets of rules align with the central tenets of the FAA, but afford parties more tangible ways to address concerns over arbitrator neutrality during the life of the proceeding.
Practical Interpretation: What Constitutes Evident Partiality?
US courts have interpreted “evident partiality” broadly in certain contexts, setting the bar at whether a reasonable person would conclude that an arbitrator was biased or failed to disclose material information. Instances that commonly trigger successful challenges include undisclosed financial interests, pre-existing relationships with a party or counsel, or repeat arbitrator appointments by one party.
UAE Legal Perspective: Recent Developments and Their Interface with US Law
With the introduction of the UAE Federal Law No. 6 of 2018 on Arbitration, modern best practices for arbitrator independence and challenge mechanisms have been enshrined. Article 15 of this law mirrors much of what is seen in leading international rules and mandates prompt disclosure of conflicts—and provides administrative mechanisms for challenge and removal by institutional bodies or courts. This convergence between US and UAE standards is significant for clients engaging in dual-jurisdiction dispute resolution frameworks.
Procedures for Challenge and Removal of Arbitrators
Stepwise Challenge Process Under US Law
1. Grounds Identification: The challenging party must articulate specific facts suggesting bias, impartiality, or incapacity, and typically must do so promptly after such facts become known.
2. Submission of Challenge: Under AAA or JAMS rules, parties file a challenge in writing to the administering institution, stating the grounds and supporting evidence (e.g., emails, prior relationships, financial disclosures).
3. Institutional Review: The institution or, in some cases, the other arbitrators in the panel, review the submission, often inviting submissions from the challenged arbitrator and opposing party.
4. Decision and Substitution: If the challenge is upheld, the arbitrator is removed and a replacement appointed per the agreed procedures. If denied, the challenger may proceed—with limited recourse until post-award review in court.
5. Court Intervention: Outside of institutional review, only in rare cases (e.g., clear statutory defects, bad faith) will courts intervene mid-proceedings. More commonly, any failure to remove a biased arbitrator is raised after the final award is issued, seeking to vacate the award under the FAA.
Practical Consultancy Guidance for UAE Businesses
- Timeliness: Delays in raising challenges may be interpreted as waiver of rights—immediate action upon discovery is essential.
- Documented Evidence: Successful challenges demand cogent, well-documented factual assertions, not speculative or tactical objections.
- Contractual Provisions: Parties should negotiate arbitration clauses carefully—explicitly providing challenge/recusal mechanisms aligned to best practices increases enforceability and clarity in cross-border settings.
Comparative Table: Evolving Standards in UAE and US Arbitration Law
| Aspect | Previous UAE Law (Pre-2018) | UAE Arbitration Law No. 6 of 2018 | US Federal Arbitration Act | Typical Institutional Rules (AAA/JAMS) |
|---|---|---|---|---|
| Disclosure Requirements | Limited, broad discretion | Mandatory; Article 15 requires proactive disclosure | No express statutory disclosure, but required by case law | Detailed, with ongoing updates expected |
| Challenge Mechanism | Court-driven, lengthy | Expedited; can be resolved by institution/courts | Primarily post-award court challenge | Administrative process during proceedings |
| Timing for Challenge | Not clearly set | Within 15 days of knowledge | Pre-award challenges rare; post-award within 3 months | Promptly upon awareness of grounds |
| Court Intervention | Frequent, broad grounds | Slimmer, only for extraordinary cases | Restrictive, only post-award or exceptional | Institutional, courts rarely involved pre-award |

Case Studies and Hypotheticals
Case Study 1: Undisclosed Relationship in a Technology JV Dispute
A UAE-based technology start-up entered arbitration with a US partner under AAA rules. During proceedings, evidence surfaced of the arbitrator’s significant past consultancy engagement with the US party’s parent company, not disclosed upon appointment. The UAE party filed a documented challenge. The AAA found that, even if not malicious, the lack of initial disclosure raised doubts as to impartiality. The arbitrator was replaced, enabling the parties to continue the proceedings with renewed confidence and preserving enforceability of any eventual award.
Case Study 2: Repetitive Arbitrator Appointments in Construction Contracts
In a series of construction disputes between a UAE developer and a US contractor, the same arbitrator was repeatedly appointed by the US contractor, raising questions of potential bias. The UAE party challenged the appointment under JAMS rules, arguing that the arbitrator’s ongoing engagements gave rise to reasonable apprehension of partiality. JAMS reviewed the matter and, upon substantiating a pattern, appointed an alternative neutral from its roster—a testament to the practical value of institutional safeguards.
Hypothetical 1: Inadequate Challenge Documentation
If, instead, a UAE company were to file a challenge lacking concrete evidence (e.g., based solely on nationality or conjecture), it is highly likely the challenge would be dismissed, underlining the importance of substance over speculation in US proceedings.
Risks, Compliance Strategies, and Best Practices
Risks of Failing to Assert or Properly Handle Challenges
- Loss of Enforceability: If bias is not raised properly or challenges are mishandled, parties may lose the ability to set aside an unfair award—a risk for UAE businesses seeking recognition of awards in US or third-country courts.
- Procedural Delays and Costs: Frivolous or belated challenges can extend proceedings, escalate costs, and damage business relationships.
- Reputational Impact: Repeated challenges without merit may harm a party’s standing before arbitral institutions and future panels.
Compliance Strategies for UAE Stakeholders
- Audit and Due Diligence: Proactively vet proposed arbitrator candidates for conflicts or relationships—use procedural checklists and demand written disclosures.
- Embed Best Practices in Contracts: Incorporate model challenge and disclosure clauses referencing AAA/JAMS rules or UAE Arbitration Law No. 6 of 2018.
- Timely Legal Consultation: Engage with qualified legal consultants in both the UAE and US to support and guide challenge procedures, ensuring compliance with all deadlines and evidentiary requirements.
- Documentation of Proceedings: Maintain an audit trail of all disclosures, communications, and challenge submissions for potential post-award proceedings.

| Challenge Submission | Prepare evidence-supported filings promptly | External Legal Advisor |
Conclusion: Outlook on Arbitrator Challenge Mechanisms
As UAE companies elevate their international profile and the volume of US-linked arbitration matters grows, mastery over the challenge and removal of arbitrators is a non-negotiable business competency. Legal and HR managers must ensure not only contractual alignment but also procedural fluency—backed by documentary diligence and cross-border legal consultation.
Anticipated trends for 2025 and beyond suggest further harmonization of UAE and US arbitration best practices, with digital disclosures, transparency mandates, and innovative recusal protocols providing increased clarity. Practically, clients are advised to:
- Regularly update arbitration policies and training to reflect latest US and UAE legal updates.
- Maintain a proactive, facts-based posture on arbitrator neutrality issues.
- Consult with specialist legal advisors to pre-empt challenges and safeguard enforceability in global transactions.
Proactive compliance is no longer merely advisable—it is critical to preserving the integrity, predictability, and enforceability of arbitral outcomes spanning UAE and US jurisdictions.
