Heckman Set the Ceiling on Protocol Design — and the Supreme Court Left It There

There is a version of mass arbitration defence that treats the problem as an engineering exercise: if per-claim fees are the vulnerability, design a protocol that never lets per-claim fees accrue. Route disputes to a provider whose rules compress thousands of claims into a handful of proceedings. Make a small number of outcomes binding on everyone. Solve the arithmetic.

Heckman v. Live Nation Entertainment is the decision that established where that engineering stops.

What the protocol did

Consumers purchasing tickets agreed to terms naming a newer arbitration provider as the exclusive forum, and adopting that provider's mass arbitration rules. Those rules could be triggered once the provider had received as few as five cases involving common issues of law or fact.

Once triggered, the protocol contemplated three confidential bellwether proceedings whose outcomes would bind all remaining claimants — claimants who had no right to participate in those proceedings, no access to what happened in them, and in many cases no way to know they had occurred at all.

The underlying claims were antitrust claims brought as a putative class action in the Central District of California. The defendants moved to compel arbitration. The district court refused, and the Ninth Circuit affirmed.

What the court held

Three holdings, each independently significant.

The delegation clause fell. Ordinarily a clear and unmistakable delegation sends even a challenge to the agreement's validity to the arbitrator. The exception is a challenge aimed specifically at the delegation clause itself — and the court found that exception satisfied. A delegation clause that routes arbitrability questions into a regime whose own procedures are unconscionable cannot survive on the strength of the delegation language alone.

The agreement as a whole fell. The court found procedural unconscionability in how the terms were presented and substantive unconscionability in what they did — describing the provider's rules in terms that have since been quoted in every practitioner note on the subject, as internally inconsistent and poorly drafted, and as stacking the deck in the drafter's favour.

Preemption did not save it. The application of California unconscionability law was not preempted by the Federal Arbitration Act. Unconscionability is a generally applicable contract defence; the FAA's saving clause preserves it; and a protocol does not acquire immunity from ordinary contract doctrine merely by being an arbitration protocol.

The doctrinal move that matters most

The durable lesson of Heckman is not any single finding of one-sidedness. It is the court's willingness to evaluate the regime as it would actually operate rather than as it read on the page.

That orientation has consequences well beyond the parties. A protocol that is facially symmetrical — both sides bound by bellwether outcomes, both sides subject to the same confidentiality — can still be substantively unconscionable if, in operation, only one side ever benefits from the symmetry. A respondent that will see every bellwether proceeding and every outcome is not similarly situated to a claimant who will see none of them, no matter how even-handed the text.

For drafters, that means facial neutrality is not a defence. For claimants' counsel, it means the strongest arguments are operational: model the queue, model the information asymmetry, and show the court what the clause does rather than what it says.

Certiorari denied

Live Nation petitioned for certiorari, framing the decision as a departure from the Supreme Court's arbitration jurisprudence and as an invitation for state courts to dismantle arbitration programmes under the banner of unconscionability. The petition drew significant attention across the defence bar.

The Court denied the petition on 6 October 2025, without comment. The Ninth Circuit's decision stands.

That denial is doing real work in the market. It is not a merits endorsement, and it establishes nothing beyond the Court's discretionary choice not to hear the case. But it removed the possibility, live for most of a year, that the whole line of unconscionability decisions would be swept aside — and it left drafters with no realistic prospect of a Supreme Court rescue for aggressive protocol design.

What survives

Heckman does not hold that bellwether structures are unlawful. It holds that this one, administered this way, by this provider, was unconscionable.

The space that remains is narrower but real: protocols with genuine outer time limits, effective and symmetrical tolling, bellwether outcomes that inform valuation rather than bind absent claimants, provider selection that a court would recognise as neutral, and information rights that let a queued claimant see what is happening to their claim. Drafting into that space is harder and less protective than what came before. It is also, after October 2025, the only space there is.
