County of San Mateo v. Chevron Corp.
The 9th Circuit has held (attached and here) that climate related tort suits are a matter of state, not federal, law. The decision remands claims brought by several California jurisdictions against fossil fuel companies to state court, defeating the companies’ attempt to have the cases addressed in federal court.
