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

Mass arbitration has reshaped the calculus for every consumer-facing platform with an arbitration clause. I cover the doctrinal landscape after Heckman, the 2024 AAA Mass Arbitration Supplementary Rules, the federal-preemption overlay, the CIPA-specific settlement trends, and the defense playbook that works in 2026.

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 several thousand individual arbitration filings, at the standard AAA Consumer Rules fee schedule, runs into the millions of dollars before any arbitrator is appointed. The defendant has not yet been heard on the merits. The settlement pressure is generated by the procedural mechanics alone.

Plaintiff-side firms (Keller Lenkner, Fairmark, Labaton Sucharow, and others) developed the playbook in matters against Uber, DoorDash, Postmates, Amazon, Hertz, Live Nation, 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). Each move has been litigated. The Ninth Circuit's 2024 decision in Heckman v. Live Nation Entertainment Inc. is the most consequential outcome.

I am Sergei Tokmakov, a California attorney (CA Bar #279869). I draft consumer-facing terms, arbitration clauses, and the documents that get challenged when a platform attracts a mass-arbitration filing. This memo is the long-form defense-side companion to the AAA consumer arbitration response roadmap and the CIPA / Meta Pixel defense hub. The audience is general counsel, founders, and outside counsel at California companies evaluating arbitration-clause exposure or responding to a current filing.

The case-law trajectory at a glance

Five California or Ninth Circuit decisions, plus the federal preemption overlay, define the current landscape. I treat each in turn below.

Postmates and DoorDash: the procedural foundation

The Postmates and DoorDash matters are where the mass-arbitration playbook was first stress-tested. In Adams v. Postmates Inc., the Ninth Circuit affirmed the district court's order compelling Postmates to pay AAA fees on thousands of individual driver demands. The decision rejected Postmates' argument that the aggregate fee exposure made the arbitration agreement unconscionable or unfair to enforce. The court reasoned that Postmates had drafted the arbitration clause precisely to require individual proceedings, and could not now complain that the plaintiffs had taken it at its word.

The DoorDash matters in the Northern District of California, beginning with Abernathy v. DoorDash Inc., reached the same result. Judge William Alsup's order in Abernathy framed the issue starkly: DoorDash had imposed a class-action waiver and individual arbitration on its drivers, and DoorDash now had to live with the consequences when the drivers' counsel filed five thousand individual demands. The court declined to halt the filings or to permit DoorDash to litigate the consolidated dispute in court instead.

The doctrinal lesson from Postmates and DoorDash is that a defendant who has drafted the class-action waiver and the individual arbitration requirement cannot then argue that the mass-arbitration consequence is procedurally unfair. The fee exposure is a feature of the contract the defendant drafted, not a bug. Defendants seeking to avoid mass-arbitration fee exposure must do so through prospective clause-drafting changes, not through retrospective procedural challenges.

MacClelland v. Cellco Partnership: telecom and fee enforcement

MacClelland v. Cellco Partnership extended the Postmates / DoorDash framework into the consumer telecommunications context. Verizon (operating as Cellco Partnership) faced a mass-arbitration filing by thousands of customers asserting telecommunications-related claims. The court's analysis followed the Postmates / DoorDash framework: Verizon had drafted the arbitration clause, the AAA fee allocation was a contractual choice, and the court would enforce the fee obligation as the plaintiffs filed.

The MacClelland holding is important for California consumer-facing platforms generally. The decision applies the mass-arbitration framework outside the gig-economy context, into the broader consumer-services category. The implication for SaaS, e-commerce, and direct-to-consumer companies is that the framework is not limited to the gig-economy cases. Any consumer-facing platform with an arbitration clause is subject to the same procedural exposure.

Heckman v. Live Nation: the limits of clause-drafting innovation

The Ninth Circuit's 2024 decision in Heckman v. Live Nation Entertainment Inc. is the most consequential recent development. Live Nation had redrafted its arbitration provisions to direct mass arbitration to New Era ADR, a smaller alternative provider with bespoke procedural rules. The redraft was designed to reduce Live Nation's exposure to mass-arbitration fees by routing the filings to a forum with different fee allocation, restricted discovery, and other procedural modifications.

The Ninth Circuit struck the provisions down. The court's analysis rested on three pillars. First, the procedural design (New Era's 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 Federal Arbitration Act's purpose of facilitating arbitration as an alternative to litigation.

The decisional reasoning 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 bespoke arbitration architectures in mass-arbitration contexts. The decisional trend through 2024 and into 2025 has been more skeptical of platform-favorable arbitration design than the 2018-2019 case law was.

The practical implication: a platform that has drafted a non-standard arbitration procedure (alternative provider, restricted discovery, modified fee mechanics, batch-resolution provisions, restricted public-injunctive-relief carve-outs) should reevaluate the clause in light of Heckman. The clause that survived a challenge in 2019 may not survive one today. Annual review is appropriate.

The 2024 AAA Mass Arbitration Supplementary Rules

AAA promulgated Mass Arbitration Supplementary Rules in 2024 in response to the mass-arbitration phenomenon. The Supplementary Rules apply when AAA receives twenty-five or more demands from the same counsel against the same respondent on similar claims (the precise threshold has been revised; verify against the current rules at adr.org).

The Supplementary Rules introduced four meaningful changes:

1. Process administrator role. A neutral process administrator manages the mass-arbitration cohort, including bellwether selection, sequencing, and information-sharing protocols. The process administrator is appointed early in the matter.
2. Bellwether process. A small set of representative cases is arbitrated first, and the results inform the resolution of the broader cohort. The bellwether selection methodology is structured to produce a representative sample rather than a cherry-picked one.
3. Modified fee mechanics. The Supplementary Rules adjust the fee allocation for mass-arbitration filings. The original 2024 per-claimant administrative fee was set at $325 (an oft-cited figure), but the schedule has been revised since the original promulgation. The general principle: the per-claimant fee on mass filings is lower than the per-claim fee under the standard Consumer Rules, but the aggregate exposure remains significant. Verify the current schedule against adr.org.
4. Sequencing protocols. The Supplementary Rules establish a timeline for the bellwether arbitrations, the global settlement window, and the resolution of the broader cohort. The sequencing limits the front-loaded fee exposure and provides a structured path to resolution.

The Supplementary Rules are a meaningful procedural tool for defendants facing mass-arbitration filings, but they are not a complete answer. The defendant still has to pay the per-claimant administrative fee, still has to participate in the bellwether process, and still has to manage the global settlement framework. The Supplementary Rules reduce, but do not eliminate, the mass-arbitration exposure.

The McGill, Iskanian, and Viking River overlay

Three overlay decisions structure how mass arbitration interacts with California public-policy and PAGA frameworks.

McGill v. Citibank: the public-injunctive-relief carve-out

McGill v. Citibank N.A., 2 Cal. 5th 945 (2017), held that a pre-dispute arbitration agreement cannot waive the consumer's right to seek public-injunctive relief under California's Unfair Competition Law, the False Advertising Law, or the Consumer Legal Remedies Act. An arbitration clause that purports to waive public-injunctive-relief claims is invalid as applied to those claims, though the rest of the clause may remain enforceable on standard severability principles.

McGill is a defense issue and a drafting issue. As a defense issue, plaintiff counsel frequently include public-injunctive-relief claims as part of the mass-arbitration filing. The defense should evaluate whether the company's arbitration clause includes a McGill-compliant carve-out, and if not, whether the public-injunctive-relief claims should be carved out for court adjudication while the individual claims proceed in arbitration. As a drafting issue, every California-facing arbitration clause should include an express McGill carve-out.

Iskanian and PAGA

Iskanian v. CLS Transportation Los Angeles LLC, 59 Cal. 4th 348 (2014), established that a representative Private Attorneys General Act action cannot be waived in a pre-dispute arbitration agreement. The doctrine survived for nearly a decade as the controlling California rule.

Viking River Cruises v. Moriana

The Supreme Court's decision in Viking River Cruises Inc. v. Moriana, 596 U.S. 639 (2022), held that the Federal Arbitration Act preempts Iskanian to the extent that Iskanian prevented division of PAGA actions between individual and representative components. After Viking River, the individual PAGA claim can be compelled to arbitration; the representative PAGA claim remains in court if the plaintiff retains standing.

Adolph v. Uber Technologies

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 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.

For mass-arbitration purposes, the Viking River / Adolph framework matters because some mass-arbitration filings include PAGA claims. The defendant should evaluate whether the PAGA claims belong in arbitration (individual) or in court (representative), and whether the bifurcation produces a defensible posture.

AB 1414 and section 1281.97 fee-payment forfeiture

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 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 proceed in court. The strictness of the rule was confirmed in Espinoza v. Superior Court, 83 Cal. App. 5th 761 (2022), and the cases following it.

Section 1281.97 cuts both ways in mass-arbitration matters. For a plaintiff firm facing a defendant slow-walking the fees, the section provides a path to court. For a defendant strategically choosing to forfeit (because the merits are strong in court and the AAA fee exposure is unacceptable), the section is the mechanism. The decision should be deliberate, not accidental.

CIPA-specific settlement trends

The mass-arbitration phenomenon has converged with the California Invasion of Privacy Act and the post-Javier wave of pixel and session-replay claims. The intersection produces a particular settlement dynamic.

Plaintiff firms have increasingly filed CIPA / pixel claims as AAA consumer arbitrations rather than as putative class actions in court. The choice is rational. The platform has typically drafted an arbitration clause that purports to require individual arbitration of consumer disputes. The platform pays the AAA fees per filing. The settlement pressure is generated by the aggregate fee exposure, not by the merits.

Publicly reported CIPA-specific mass-arbitration settlements have generally been structured at modest per-claimant amounts (typically in the low hundreds of dollars per named claimant) combined with injunctive commitments (the platform commits to consent-banner remediation, pixel-implementation changes, vendor-contract updates). The cash component is calibrated to make the matter resolvable; the injunctive component reflects the underlying remediation that the platform would have done anyway in response to litigation pressure.

The aggregate settlement amounts are large but the per-claimant figures are modest. The dynamic favors plaintiff firms that can aggregate large cohorts efficiently and platforms that can negotiate global settlements that resolve broad swaths of related claims simultaneously. Single-claimant CIPA arbitrations are a different category of matter and tend to settle at higher per-claimant amounts because the defendant is not facing the fee-aggregation pressure.

Counsel evaluating a CIPA settlement framework should distinguish the matter's aggregate exposure from its per-claimant exposure, and should structure the settlement to align with the underlying matter economics. A coupon-and-injunctive settlement that works for a thousand-claimant cohort may be the wrong structure for a ten-claimant matter.

The drafting options remaining

For a platform whose business model depends on bounded litigation exposure, the drafting options after Heckman, AB 1414, and the 2024 Supplementary Rules 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. This is the cleanest option for most platforms.
2. Standard AAA arbitration with the Mass Arbitration Supplementary Rules. The platform's arbitration clause expressly incorporates the Supplementary Rules procedural framework, including the bellwether process and the modified fee mechanics. This option preserves the arbitration architecture while reducing the front-loaded fee exposure.
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 carefully avoid one-sided fee provisions, restricted discovery, and impracticability arguments. Most platforms cannot defend a bespoke procedure under current law; the marginal cases that can are typically large platforms with bargaining power and counsel willing to defend the clause through appellate review.
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. For platforms with strong substantive defenses (party-to-the-communication, consent, statute-of-limitations), class litigation may be preferable because the merits get tested. For platforms with weak substantive defenses, arbitration with settlement is preferable because the merits do not get tested.
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. Impracticability arguments may apply if the procedure is too restrictive.
6. Public-injunctive-relief carve-out. The arbitration agreement preserves the right to seek public-injunctive relief in court, consistent with McGill v. Citibank. The carve-out preserves the McGill rule and reduces the risk of the entire clause being held invalid for failing to do so. Every California-facing arbitration clause should include this.

Defense playbook: positioning for early settlement versus fighting

The strategic question every mass-arbitration defendant faces: do I position for early settlement or do I fight?

Position for early settlement when

• The substantive merits are weak or unsettled (pixel cases under section 638.51 fall here for many defendants)
• The aggregate cohort size is large enough that fee exposure exceeds any plausible settlement
• The injunctive remediation is something the platform would do anyway
• The arbitration clause is solid (formation clean, scope clear, post-Heckman compliant)
• The insurance coverage supports defense-cost-only protection rather than indemnity

Fight when

• The substantive merits are strong (clean consent record, defensible vendor agreements, statute-of-limitations defense)
• The aggregate cohort size is small enough to absorb the fee exposure
• The arbitration clause has a vulnerable provision (post-Heckman risk, formation gap, scope dispute) and the company would benefit from gateway-jurisdiction adjudication
• Insurance coverage supports the merits defense, not just the procedural posture
• The settlement framework the plaintiff firm is offering would establish a problematic precedent for future matters

The standstill option

Between "settle early" and "fight" is the standstill agreement. A negotiated standstill suspends additional AAA filings (or suspends the fee clock on existing filings) for a defined period while the parties evaluate the matter. Most plaintiff firms will engage on a standstill if the defendant signals serious settlement intent. The standstill is useful when the company needs time to evaluate the merits, gather facts, or align internal stakeholders.

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. The platforms that have done well in this environment are the ones that (a) have current, defensible clauses, (b) have documented consent and vendor frameworks, (c) have a written incident-response playbook, and (d) have insurance coverage they have actually read.

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 additional legislative measures 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.

The Federal Arbitration Act remains the controlling federal framework. Significant federal preemption rulings (Viking River, Coinbase v. Suski) continue to shape the interaction with California's consumer-protective rules. Counsel should not assume that federal preemption will rescue an otherwise vulnerable clause; the Heckman court applied California unconscionability law within an FAA-aware framework and the clause did not survive.
