AAA Mass-Arbitration Tactics and the 2023-2025 California Case Law Response

Mass arbitration has reshaped the calculus for any consumer-facing platform with an arbitration clause. I will walk through the doctrinal landscape after Heckman, the legislative response, and the limited drafting options remaining.

The mass-arbitration phenomenon emerged when plaintiffs' counsel realized that consumer arbitration agreements with class-action waivers could be activated, in aggregate, by filing thousands of individual demands simultaneously. Each individual demand triggers AAA filing fees that the business is contractually obligated to pay. The aggregate fee exposure for ten thousand individual arbitration filings, at the standard AAA Consumer Rules fee schedule, runs into the millions of dollars before any arbitrator is appointed.

Plaintiff-side firms (Keller Lenkner, others) developed the mass-arbitration playbook in matters against Uber, DoorDash, Postmates, Amazon, and other consumer-facing platforms. The platforms' response, through the 2020-2024 period, was to renegotiate fee arrangements with AAA, to draft alternative arbitration procedures, and in some cases to redirect arbitration to alternative providers (New Era ADR, FairClaims, or other forums). Each of these moves has been litigated, and the Ninth Circuit's 2024 decision in Heckman v. Live Nation Entertainment Inc. is the most consequential outcome.

What Heckman decided

The Ninth Circuit in Heckman v. Live Nation (2024) struck down Live Nation's arbitration provisions, which had been redrafted to direct mass arbitration to New Era ADR. The court held that the provisions, which the court characterized as designed to discourage and impede individual and collective claims, were unconscionable under California law and unenforceable under the Federal Arbitration Act.

The decision's reasoning rested on three pillars. First, the procedural design (New Era's procedural rules, including limited discovery, restricted hearing rights, and certain fee allocations) was substantively unconscionable. Second, the bilateral fee-shifting provisions were one-sided in operation. Third, the practical effect of the provisions was to make individual arbitration impracticable, which the court treated as inconsistent with the FAA's purpose of facilitating arbitration as an alternative to litigation.

The Ninth Circuit's analysis explicitly addressed AAA's complicity in similar protocols, though the court did not strike down AAA's standard procedures. The case has been cited by lower courts evaluating arbitration provisions in mass-arbitration contexts. The decisional trend through 2024 and into 2025 has been more skeptical of bespoke arbitration architectures than the 2018-2019 case law was.

The AB 1414 response

California's AB 1414, signed in 2023, modified the section 1281.97 framework to clarify the procedural mechanics for arbitration fee non-payment. The amendment reinforced the rule that a business that drafts an arbitration clause and fails to pay arbitration fees within thirty days of their due date waives the right to compel arbitration. The amendment also addressed certain procedural details and clarified ambiguities in the prior text.

The combined effect of AB 1414 and the Heckman line is to give plaintiffs' counsel real procedural leverage in mass-arbitration contexts. The business cannot use procedural delay to bleed plaintiffs' counsel; if the business fails to pay timely, the contractual right to arbitration is forfeited and the plaintiffs can proceed in court.

The drafting options remaining

For a platform whose business model depends on bounded litigation exposure, the drafting options after Heckman and AB 1414 are constrained:

  1. Standard AAA Consumer Rules arbitration with class waiver. The platform pays the fees, accepts the mass-arbitration exposure, and responds with settlement or arbitration on the merits. The exposure is real but the procedure is unchallenged.
  2. Standard AAA arbitration with batching protocols. The platform negotiates with AAA for batching procedures (test cases, sequenced filings, fee adjustments) that limit the front-loaded fee exposure. AAA has adopted some mass-arbitration protocols. The batching is subject to challenge if it materially impedes individual rights.
  3. Bespoke arbitration procedure. The Heckman line makes this approach high-risk. Drafting an arbitration procedure that materially differs from AAA's standard rules invites the Heckman analysis. The drafting must be careful to avoid one-sided fee provisions, restricted discovery, or impracticability arguments.
  4. Mass-action permitted. Some platforms have moved to permit class actions in court rather than maintain the arbitration architecture. The exposure is to class litigation rather than individual arbitration. Whether this is preferable depends on the substantive merits and the platform's posture.
  5. Mediation-first procedure. The platform requires informal dispute resolution (negotiation, mediation) before any arbitration filing. The procedure can delay mass filings but cannot eliminate them, and impracticability arguments may apply.
  6. Public-injunctive-relief carve-out. The arbitration agreement preserves the right to seek public-injunctive relief in court, consistent with McGill v. Citibank N.A., 2 Cal. 5th 945 (2017). The carve-out preserves the McGill rule and reduces the risk of the entire clause being held invalid for failing to do so.

The Viking River and Adolph overlay

The Supreme Court's decision in Viking River Cruises Inc. v. Moriana, 596 U.S. 639 (2022), held that the Federal Arbitration Act preempts California's prior Iskanian rule to the extent that Iskanian prevented division of PAGA actions between individual and representative components. The California Supreme Court's response in Adolph v. Uber Technologies Inc., 14 Cal. 5th 1104 (2023), held that a PAGA plaintiff retains standing to pursue the representative PAGA claim in court even after the individual claim is compelled to arbitration.

The combined Viking River/Adolph framework reshapes the PAGA landscape for platforms with employee misclassification or wage-and-hour exposure. The individual PAGA claim goes to arbitration. The representative PAGA claim, if the plaintiff has standing, proceeds in court. The platform faces a bifurcated proceeding with arbitration on the individual claim and court litigation on the representative claim. Strategically, the platform may prefer to keep the individual claim in court rather than splitting the proceeding, depending on its assessment of the representative claim's merits.

The settlement economics

The economics of mass arbitration favor settlement in most matters. The platform's exposure to AAA fees, arbitrator fees, and the time and cost of individual arbitrations is meaningful even when the underlying merits are weak. Plaintiffs' counsel's economics rely on the aggregate value of the settled mass-arbitration matters. The negotiated settlement, often structured as a coupon or partial-refund program, can resolve the matter at lower aggregate cost than running thousands of individual arbitrations.

The drafting move that supports this dynamic: include in the arbitration agreement a clause that permits the parties to negotiate group settlements, with the platform's commitment that any group settlement will be presented to AAA for review under its consumer-protocol guidelines. The clause does not bind the plaintiffs but signals the platform's willingness to engage in good faith.

The legislative future

California legislative attention to consumer arbitration has been sustained. SB 707, AB 1414, and related measures have tightened the procedural framework. Counsel should expect that additional legislative measures will appear in the 2026-2028 cycle, particularly addressing platform-specific arbitration practices, mass arbitration economics, and consumer protection in digital-economy contexts. The federal landscape is less active but the FAIR Act and similar federal proposals remain on the agenda.

What I would not assume

The arbitration landscape in 2026 is meaningfully different from the landscape in 2020. The doctrinal trajectory is toward more skepticism of platform-favorable arbitration architectures and more procedural tools for plaintiffs' counsel. Counsel advising platforms on arbitration clauses should not assume that prior practice is current. The clause that worked in 2018 may now create more exposure than it limits. The drafting review should be annual, and the response to a mass-arbitration filing should be developed in advance rather than improvised. Outcomes in specific matters depend on the clause, the platform, the plaintiffs, and the procedural posture. The aggregate trajectory is what counsel should plan against.
