Answer:
Original jurisdiction refers to the Supreme Court's authority to hear a case for the first time.
Step-by-step explanation:
Original jurisdiction is the Courts' authority to hear a case in the first instance, that is to say, before any appellate review hears it. In the United States, there are few cases in which the Supreme Court has original jurisdictions, some of them include all cases affecting Ambassadors, public Ministers and Consuls, controversies between the United States and a State, and inter-state conflicts.
