Supreme Court Hands Win to Tennessee in Water Resource Fight

The U.S. Supreme Court found that Tennessee didn’t steal groundwater from Mississippi, in a dispute with wide-ranging implications for how states manage natural resources.

The justices in Mississippi v. Tennessee said in a unanimous decision that interstate groundwater is covered by equitable apportionment, which is the standard process by which water resources are shared.

It’s the high court’s first use of the equitable apportionment doctrine related to interstate groundwater.
