Coinbase v. Suski

Summary

The Supreme Court affirmed the Ninth Circuit, holding that when parties have entered into two contracts—one containing an arbitration delegation clause and another containing a forum‑selection clause—a court, not an arbitrator, must decide which contract governs the arbitrability question. The Court reasoned that the existence of a valid arbitration agreement is a matter of contract consent and therefore must be determined by the court before any delegation provision can be enforced.
