Glover's Taxonomy: Why Mass Arbitration Is Not a Variation on Anything

Every account of mass arbitration written since has been, to some degree, a response to this one. J. Maria Glover's article in the Stanford Law Review supplied the first case study and taxonomy of the practice, and framed the questions the field has been arguing about ever since.

The starting condition

The article begins with what the arbitration revolution accomplished. After two decades of successful defence-side campaigning — culminating in the enforceability of class waivers in consumer contracts and then in employment agreements — vast categories of claim were effectively removed from adjudication.

Glover is specific about which categories: civil rights claims, wage theft, sexual harassment, consumer fraud. And specific about the distributional consequence, which is that foreclosure fell disproportionately on minorities, women, wage workers, and low-income individuals. These were not claims that lost. They were claims that were never brought, because the forum in which they had to be brought made bringing them irrational.

That framing is essential to reading the rest. Mass arbitration is not, on this account, an abuse of a functioning system. It is a response to a system that had stopped functioning for a very large class of claimants.

The reversal

The article's central empirical observation is the one that gave it immediate purchase: prominent defendants began abandoning the arbitration clauses they had spent years securing, and seeking the protection of class actions instead.

The irony is close to complete. Class waivers were designed to prevent aggregate exposure. They produced a form of aggregate exposure that some defendants found worse than the class actions they had been avoiding — because a class action resolves ten thousand claims in one proceeding with one set of costs, while ten thousand individual arbitrations generate ten thousand sets of administrative fees before anyone reaches the merits.

Companies that reached that conclusion did not merely amend their protocols. They removed the arbitration requirement altogether, accepting class exposure as the cheaper risk.

Why "new model" is the load-bearing claim

Glover's structural argument is that mass arbitration is not a variation on class actions, not a variation on MDL, and not simply arbitration at scale. It is a distinct model of dispute resolution with its own logic.

The distinction is real and worth stating precisely. In a class action, aggregation is a procedural device: a court certifies a class, and absent members are bound by a judgment they took no part in. In an MDL, aggregation is administrative: cases are consolidated for pretrial purposes but remain individually owned, and bellwether verdicts inform valuation without binding anyone else.

In mass arbitration, aggregation is neither. Every claim is formally individual, each with its own demand, its own fee, and its own arbitrator. No procedural rule aggregates them. What aggregates them is counsel and cost structure — the fact that one firm holds all of them, and that the respondent's per-claim administrative liability accrues in parallel.

That is genuinely a different mechanism, and it is why doctrine developed for class actions and MDLs maps onto it so poorly. It also explains why the contest has migrated into contract law: with no procedural rule to attack, the fight is over the enforceability of the terms that constitute the process.

The theoretical consequence

The article's final move is to unsettle a settled proposition. Conventional litigation theory held that negative-value claims — claims worth less than the cost of pursuing them individually — cannot be litigated without a procedural aggregation device. That premise underwrote the case for class actions and, in the arbitration cases, underwrote the conclusion that individual arbitration was an adequate substitute forum.

Mass arbitration falsified it. A portfolio of negative-value claims turned out to be economically viable without any aggregation device at all, provided the cost structure of the forum runs against the respondent. The theory had described a constraint that was contingent on institutional design rather than intrinsic to small claims.

Four years on, that observation has aged well. Everything the provider rules and the redrafting wave have done since is an effort to restore the constraint by changing the cost structure — flattening initiation fees, interposing gatekeepers, requiring vetting, staging the queue. The fight over mass arbitration is, at bottom, a fight over whether small claims are economically viable, conducted through fee schedules and procedural preconditions.
