Supreme Court of the United States

Florida v. California

May 26, 2026

Summary

Justice Thomas, joined by Justice Alito, dissents from the Court's denial of Florida's motion for leave to file a complaint against Washington and California. The dissent argues that the Supreme Court has no discretion to refuse original jurisdiction over disputes between states and that Florida's claim meets the two‑factor test for exercising that jurisdiction. Accordingly, Thomas would have granted leave.
