Supreme Court of the United States

Alabama v. California

March 10, 2025

Summary

Justice Thomas, joined by Justice Alito, dissents from the Supreme Court's denial of a motion for leave to file a bill of complaint in a multi‑state suit alleging that certain defendant states are using tort litigation to impose a de facto carbon tax on out‑of‑state energy companies. The dissent argues that the Constitution and 28 U.S.C. §1251 give the Court compulsory original jurisdiction over controversies between states and that the Court should not decline to exercise that jurisdiction.
