The Supreme Court appointed a Special Master in 2015 to hear the case and take evidence on the facts at issue. After discovery, motion practice, an evidentiary hearing, briefing on the issues and closing arguments, the Special Master issued a report agreeing with MLGW and Tennessee that the water at issue is an interstate resource. In addition, under well-settled Supreme Court precedents, the appropriate remedy for a dispute between states over interstate resources is an equitable apportionment action, which is a remedy that does not involve any money damages but seeks to allocate use of an interstate natural resource based on facts and circumstances including historical use and needs. Based on his analysis, the Special Master recommended dismissal of the case, with leave to Mississippi to seek an equitable apportionment, a remedy that Mississippi has so far disclaimed any interest in pursuing. This significant ruling is a wonderful tribute to Leo's extraordinary career.
