This Supreme Court ‘victory’ for oil giants is not what it seems

For millions of years, the Mississippi River flowed unchecked, carrying roughly 400 million metric tons of sediment down to Louisiana, where it spilled into the Gulf of Mexico to create new land. But in the early 20th century, a series of dams and river-training structures were built to prevent flooding — leaving the river tamed and unable to produce new terrain at anywhere near its previous pace. Oil and gas development, which ripped broad canals through vulnerable marshland, made matters worse. As sea levels rose, existing land subsided, and more brutal storms battered the coast. Louisiana lost more than 2,000 square miles of wetlands over the last century, a slow dismantling exacerbated by climate change. About a football field or more land disappears every 100 minutes, and the state’s southern parishes are expected to lose another 3,000 square miles by 2050 unless drastic action is taken. After years of devastating hurricanes, many of Louisiana’s southernmost towns have been emptying out. Complex restoration efforts remain the state’s best hope, but the Supreme Court hampered these initiatives earlier this month when it unanimously ruled that a lawsuit filed by Plaquemines Parish against Chevron — accusing the company of damaging coastal wetlands and accelerating land loss — should be moved to federal court, rather than the state court in which it was filed. The ruling effectively cancels a $745 million judgment against Chevron, decided before its appeal landed in front of the Supreme Court, and sets up a rematch of a decade-long legal fight. “Frankly, it’s a ridiculous situation,” said Patrick Parenteau, emeritus professor at the Vermont Law and Graduate School. “All this time and effort has gone into litigating these issues before a jury in Louisiana. Now you have to do it all over again, but you’re doing it sort of up the street in the federal courthouse.” Federal courts are generally seen as more industry friendly, and the Supreme Court’s ruling
