The Process Arbitrator: An Essential Role in Mass Arbitration

In the world of arbitration, where efficiency, fairness, and structure are prized, the American Arbitration Association’s introduction of the Process Arbitrator role under its Mass Arbitration Rules has created a useful new dynamic — one that deserves close attention by advocates handling high-volume or multi-party arbitration cases.

Implemented approximately a year ago, the AAA’s Mass Arbitration Supplementary Rules are designed to bring order and predictability to a notoriously chaotic corner of dispute resolution. One of the most consequential aspects of these rules is the formalization of the Process Arbitrator—a neutral charged with overseeing and resolving procedural disputes before they ever reach the Merits Arbitrator.

Understanding this role is more than just procedural housekeeping. For advocates, especially those navigating the surge in mass filings, the Process Arbitrator can significantly influence the flow, fairness, and even the outcome of a case—without ever touching the underlying claims.

What Is a Process Arbitrator?

Under Rule MA-6 of the AAA’s Mass Arbitration Rules, the Process Arbitrator is a separate neutral assigned specifically to address procedural disputes. These include matters related to:

• Filing sufficiency and compliance with conditions precedent

• Payment or disputes over administrative and arbitrator fees

• Selection and appointment of Merits Arbitrators

• Determination of hearing locale

• Discovery disputes and non-dispositive motions

• Any “non-merit issues affecting case administration” (Rule MA-6(c)(xi))

The goal is straightforward: to streamline the arbitration process by creating a separate lane for procedural issues, allowing the Merits Arbitrator to remain focused on the substance of the dispute — and to remain insulated from procedural friction.

Why the Role Matters: Efficiency, Neutrality, and Fairness

For parties and counsel alike, the creation of a Process Arbitrator introduces significant advantages:

1. Reduces Procedural Gridlock

Mass arbitration filings often involve dozens, hundreds, or even thousands of similar claims, sometimes orchestrated as part of coordinated legal campaigns. Without a mechanism to resolve threshold procedural issues efficiently, the entire process can grind to a halt before any party even gets close to a merits hearing.

By assigning one neutral to handle issues such as whether the parties have satisfied pre-filing obligations or whether fees have been correctly paid, the AAA reduces unnecessary delay. The Process Arbitrator’s sole focus is to keep the wheels turning — ensuring that logistics don’t overshadow substance.

2. Protects the Merits Arbitrator’s Neutrality

In traditional one-arbitrator proceedings, the arbitrator is often asked to decide pre-hearing procedural motions, discovery disputes, and other hotly contested issues long before evaluating the case itself. This can create the risk — or at least the appearance — of bias or pre-judgment.

By segregating roles, the Mass Arbitration Rules ensure that the Merits Arbitrator remains removed from early procedural tension. This preserves neutrality, enhances the credibility of the final award, and builds trust among the parties that the hearing on the merits is truly impartial.

3. Adds Predictability to Complex Arbitration

When multiple cases are filed simultaneously — each at a different stage, with different claimants, and potentially different factual wrinkles — consistency becomes a challenge. Having a dedicated Process Arbitrator helps promote procedural consistency across the docket. Whether it’s a common dispute over whether filing conditions have been met or repeated issues around scheduling or document exchange, a single process-focused neutral brings coherence to the overall structure.

How Rule MA-6 Defines the Scope of the Process Arbitrator’s Powers

Rule MA-6 of the AAA’s Supplementary Rules lays out both the authority and responsibilities of the Process Arbitrator. While the rule provides a concrete list of powers, subsection (c)(xi) functions as a catch-all: empowering the Process Arbitrator to resolve “any other non-merit issues affecting case administration.”

This language is especially significant.

In practice, this means the Process Arbitrator may rule on:

• ESI and document production disputes

• Scheduling disagreements and motion timetables

• Objections to arbitrator appointments

• Challenges to compliance with pre-arbitration notice or cooling-off provisions

• Disputes over bellwether selection or batching

• Confidentiality concerns in high-volume proceedings

Moreover, Rule MA-6(d) affirms that the Process Arbitrator has the authority to rule on their own jurisdiction. That clause echoes the well-known Kompetenz-Kompetenz principle and may become pivotal in cases where one party challenges the scope of the Process Arbitrator’s authority.

Given this range of responsibilities, selecting an experienced and even-handed Process Arbitrator is as critical as selecting the Merits Arbitrator.

Strategic Considerations for Counsel

Counsel in mass arbitration matters must rethink how to approach pre-merits advocacy. Success at the process stage can significantly impact both timing and leverage. A few key considerations:

✅ Anticipate Procedural Disputes

Before the arbitration begins, assess where friction may arise — whether in the form of pre-conditions to filing (like negotiated “cooling-off” periods), fee allocations, or batch processing of claims. Developing a procedural strategy early can allow for more effective presentation before the Process Arbitrator.

✅ Craft Procedural Arguments Thoughtfully

Because the Process Arbitrator is not evaluating the case’s factual merits, submissions should be laser-focused on rule compliance, fairness, and efficiency. Arguments rooted in administrative burden, inconsistency, or gaming of the rules are especially relevant in this context.

✅ Preserve the Narrative Without Overshadowing It

Although procedural arguments should be tightly framed, they can still lay the groundwork for later claims or defenses. Subtle context can help the Process Arbitrator understand the broader dynamics without straying into merits territory.

✅ Select Your Arbitrators with Intent

While some Process Arbitrators are assigned, others may be agreed upon by the parties. Choose someone who is not only efficient and detail-oriented, but also familiar with mass arbitration practice and the unique dynamics of coordinated filings. A Process Arbitrator who understands both the letter and spirit of Rule MA-6 can shape a smoother, more principled path to resolution.

A Role That’s Growing in Importance

As mass arbitration continues to evolve — particularly in response to corporate arbitration clauses and new litigation strategies — the Process Arbitrator’s role is likely to grow in significance. For neutrals, this development offers an opportunity to specialize in a niche that demands procedural fluency, decisiveness, and fairness.

For advocates, this role introduces a new tactical dimension to arbitration: one where a well-argued procedural point can shift momentum long before the first witness is called.

In this landscape, arbitrators who bring both substantive insight and procedural discipline are best positioned to support efficient and equitable outcomes.
