Where it stands
Decided

Decided 9-0 · May 23, 2024 · Opinion by Justice Jackson

What it’s about
The Supreme Court unanimously ruled that when parties execute two conflicting contracts—one mandating arbitration and a later one sending disputes to court—a judge, rather than an arbitrator, must decide which agreement governs.
Who it affects
Businesses and consumers with multiple agreements may get a court decision on where their dispute belongs before arbitration begins. For example, a later contest agreement can affect whether an earlier arbitration clause controls.

The decision draws a line between disputes parties delegated to an arbitrator and disputes over whether a later contract changed that delegation.

What the Court decided

Holding
