What each side argues
Petitioner (Oxford Health Plans LLC)
Oxford argues that the arbitrator interpreted the contract, but did so incorrectly.
Oxford maintains that the class action should be resolved through arbitration.
Oxford says it has always maintained that the arbitrator’s decision is final and, after Stolt‑Nielsen, asked the arbitrator to reconsider his 2003 opinion.
Respondent (John Ivan Sutter)
Source-limited. The record does not yet support a complete account.
What happened at oral argument
Oral argument began at 10:04 a.m. before the Supreme Court.
Seth P. Waxman appeared for the petitioner; Eric D. Katz appeared for the respondent.
What the Court decided
Why it matters
The case raises important questions about the scope of arbitrators’ authority over class arbitration, which could affect how courts handle class‑action disputes.
The issue is significant because the AAA class‑arbitration rules were adopted after the Court’s decision in Bazzle, underscoring ongoing uncertainty about class arbitration.
