The Supreme Court ruled California lacked specific jurisdiction (authority over claims linked to a defendant’s state contacts), overturned the California Supreme Court’s decision, and sent the case back to that court (remanded).

The dispute asked whether claims by people who lived outside a state could be heard there based on the company's connections to that state.

— Justice Sotomayor(dissent)
