Pulse Analysis

The United States’ pivot away from class actions began with Supreme Court rulings such as *Stolt‑Nielsen* and *AT&T Mobility v. Concepcion*, which fortified arbitration clauses while eroding collective litigation. DoorDash’s 2020 showdown, where drivers collectively pursued arbitration and the court compelled the company to participate, exemplifies how individual arbitration demands can coalesce into a de‑facto class action. By 2022, mass‑arbitration filings comprised over 80% of the docket at the nation’s two largest arbitration providers, straining systems designed for one‑on‑one disputes and prompting fee‑schedule overhauls and bellwether processes.

Corporations have reacted by embedding mass‑arbitration waivers in contracts or, paradoxically, reinstating class‑action options to sidestep the front‑loaded costs of coordinated arbitrations. Uber, Amazon and others now face logistical burdens and settlement pressures that bilateral arbitration was never meant to absorb. Legal pushback has followed, as seen in *Heckman v. Live Nation*, where a Ninth Circuit panel deemed a mass‑arbitration scheme unconscionable under California law due to its bellwether precedent‑setting and limited discovery. These developments underscore the volatility of relying on a single procedural tool; when economic incentives remain unaddressed, claimants will regroup in the next viable forum.

Brazil presents a pre‑crisis mirror. Mandatory arbitration clauses are embedded in corporate bylaws, yet the country lacks a statutory regime for collective arbitration, leaving a legislative gap that could explode if a market‑wide event triggers thousands of similar claims. The Brazilian model also features “extraordinary” representatives—public prosecutors and qualified associations—who can act outside individual arbitration agreements, creating potential parallel proceedings. To avoid the reactive scramble seen in the U.S., Brazil must pursue a two‑track strategy: institutional reforms within its arbitration bodies and clear legislative guidance on representation and binding effect. The broader lesson is clear—systems that suppress aggregation merely relocate it, and proactive design is essential to maintain legitimacy and efficiency in dispute resolution.
