U.S. Supreme Court Weighs Louisiana Coastal Lawsuits as Business Leaders Warn of Economic Fallout

As the U.S. Supreme Court turns its attention to Louisiana, Will Green, president and CEO of the Louisiana Association of Business and Industry, outlined what’s at stake in the long-running coastal lawsuits against oil and gas companies. At the center of the hearing is a key legal question: should the Plaquemines Parish case against Chevron—and similar lawsuits—have been heard in state court, or should they be moved to federal court because the alleged activity occurred under federal permits, some dating back to World War II.Green emphasized the economic significance of the energy sector, which supports roughly 350,000 jobs and contributes about $54 billion annually to Louisiana’s economy. He argued that more than 40 coastal lawsuits filed since 2013 have created uncertainty, discouraged investment, and pushed jobs and capital to competing states like Texas. The Supreme Court’s decision, he said, is not about assigning blame for coastal erosion but about determining the proper venue for these cases.If the court rules that the Chevron case belongs in federal court, the state-court verdict could be nullified and set precedent for moving all similar lawsuits to federal jurisdiction. Green said such a ruling would bring greater predictability and clarity for businesses operating in Louisiana, potentially reshaping the future of the state’s energy industry and its broader economy.
