For use in a WIP,
As I read the U.S. Constitution on the powers of the Supreme Court, it is, in general, a court that hears appeals from lower courts. But in some instances, the Supreme Court has "original jurisdicton," which I think means it's where the case is tried for the first time. One of those instances listed is "controversies between two or more states."
If the Supreme Court has held an actual trial of a controversy between states during my lifetime, I don't recall it. My search skills are insufficient to know what search terms I should use to find a record of such a trial.
Anybody here know of an actual instance of such a trial, or, if not, search terms that would help me find one or more?
