In Term-Opener, Justices Will Hear Mississippi’s Complaint that Tennessee Is Stealing Its Groundwater

Mississippi v. Tennessee is not only the Supreme Court’s first oral argument of the 2021-22 term, but it is also the first time that states have asked the court to weigh in on how they should share an interstate aquifer. The court’s decision could fundamentally restructure interstate groundwater law in the United States for decades -- or the case could be dismissed immediately on the grounds that Mississippi has failed to allege the proper cause of action.
