"Six Louisiana coastal parishes sued Big Oil over the erosion of coastal wetlands a decade ago, but they’re still fighting over what court should hear the case.

A judge who called the fight over jurisdiction “shameful” has since died and the parishes’ counsel complain that delays have impacted their ability to use certain aging expert witnesses.

The case will reach the Supreme Court on Monday, where the justices will hear arguments over whether Chevron USA Inc. can move a pair of disputes from state to federal court.

It could directly affect about a dozen matters, including the one case that went to trial and ended with a jury verdict ordering Chevron to pay $745 million towards restoring wetlands whose deterioration has made the region more vulnerable to extreme weather."
