What it's about

The Supreme Court held that the New York Convention does not bar that result, so nonsignatories may rely on those domestic doctrines when appropriate.

This case connects international arbitration under the New York Convention with state-law contract rules about when a company that did not sign an agreement may enforce it.

Question presented

Whether the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the "New York Convention") permits a non-signatory to an arbitration agreement to compel arbitration based on the doctrine of equitable estoppel.

What the Court decided

Holding

The New York Convention does not conflict with domestic equitable estoppel doctrines that permit the enforcement of arbitration agreements by nonsignatories. 902 F. 3d 1316, reversed and remanded.
