Plaquemines Parish case against Chevron centers on federal court jurisdiction and state judgmentNEW ORLEANS — Louisiana Attorney General Liz Murrill says the first day of oral arguments in Plaquemine Parish’s case against Chevron centered on whether the case could stay in federal court and what would happen if it does. Backed by the Trump administration, Chevron and others had asked that the lawsuits be considered in the federal court system. In April, the U.S. Supreme Court ruled the case should be heard in federal court. "Chevron obviously wants to wipe out the judgment we obtained in state court and we think whether we're in federal court or not, that judgment still survives," Murrill said. Murrill said the state already proved its case at trial and Chevron has not been able to explain its position.
