This Article focuses on an area of rapidly evolving jurisprudence—climate liability litigation. It examines in depth the state attorney general’s complaint filed in Rhode Island v. Chevron Corp. in 2018, alleging various state-law tort claims. It explores the intensely sustained legal battles taking place between states and fossil fuel companies over whether federal courts or state courts should have jurisdiction, which in many respects is the “ballgame issue” for both plaintiffs and defendants.
