On November 22, 2021, the United States Supreme Court issued a ruling on whether Tennessee is liable for damages and other relief related to the pumping of groundwater by the City of Memphis from the Middle Claiborne Aquifer which lies beneath eight states. The Supreme Court ruled in a precedent setting opinion that the waters of the Middle Claiborne Aquifer are subject to the judicial remedy of equitable apportionment and that Mississippi’s complaint is dismissed without leave to amend.
