Summary: written with AI from the case record.

What it's about
The Supreme Court agreed with the lower court that the arbitrator did not exceed his authority by interpreting the contract to allow it; the Court’s review did not decide whether that interpretation was correct.
The contract broadly required arbitration but did not expressly say whether a dispute could be arbitrated on behalf of a group.
Question presented
Does an arbitrator exceed his authority when he determines that parties agreed to class arbitration based only on broad contractual language precluding litigation and requiring arbitration of any dispute arising under their contract?
What the Court decided
Holding
The arbitrator’s decision survives the limited judicial review allowed by §10(a)(4). Pp. 4 − 9. 675 F. 3d 215, affirmed.
- Result
- Affirmed
The Court's reasoning
The Court said federal law permits only limited court review of an arbitrator’s authority, and the decision survived that review. It did not decide whether the arbitrator had read the contract correctly.
The vote
What's next
The Supreme Court’s review is complete, and the arbitrator’s decision remains in place.
