Chevron Corp. v. County of San Mateo

In the cases brought by County of San Mateo, two other California counties, and three California cities, the Supreme Court granted the fossil fuel companies' petition for writ of certiorari seeking review of the Ninth Circuit's decision affirming the district court's remand order. The Court vacated the Ninth Circuit's judgment in the case and remanded for further consideration in light of its decision in BP p.l.c. v. Mayor & City Council of Baltimore holding that the Fourth Circuit should have reviewed grounds for removal other than the federal officer removal statute. Justice Alito did not take part in the consideration of the case.

In December 2020, the fossil fuel companies filed a petition for writ of certiorari seeking review of the Ninth Circuit decision affirming remand orders in cases brought by the County of San Mateo and other California local governments. The companies requested that the petition be held pending the outcome of the Baltimore case since their petition raises the same jurisdictional issue.
