[JURIST] The US Supreme Court [official website; JURIST news archive] agreed [order list, PDF] Monday to hear oral arguments in the case of South Carolina v. North Carolina to decide whether additional parties may intervene in a lawsuit between two states, over which the Court has original jurisdiction. A special master recommended [report, PDF] that three parties - the city of Charlotte, North Carolina, the Catawba River Water Supply Project, and Duke Energy Carolinas - be allowed to intervene in the lawsuit brought by South Carolina over water flows from the Catawba River. The state of South Carolina and the US government both dispute that recommendation, arguing that the states should speak for the interests of all their citizens.
