Summary: written with AI from the case record.
What it's about
The petition was distributed for a Supreme Court conference, but that does not mean the Court agreed to hear the case.
The agreement is covered by an international treaty on arbitration, and equitable estoppel is the fairness rule at the center of the dispute.
Question presented
Does federal common law or state law determine whether a nonsignatory to an arbitration agreement governed by the Convention on the Recognition and Enforcement of Foreign Arbitral Awards can use equitable estoppel principles to enforce the agreement?
What happens next
The next step is for the Court to decide whether to hear the case. The petition was distributed for the Nov. 6, 2026, conference, but that date does not guarantee an order.
