The U.S. Supreme Court on April 17 sided unanimously with oil company Chevron, ruling that a pollution lawsuit in Louisiana should be heard in federal court.

The court’s 8–0 opinion in Chevron USA Inc. v. Plaquemines Parish was authored by Justice Clarence Thomas. Justice Samuel Alito previously recused himself from the case, citing a financial conflict of interest.
