Definition - What does Original Jurisdiction mean?
Original jurisdiction refers to the authority and power of a court to hear a lawsuit or hold a trial and pass on a judgment purely based on facts and law. The original jurisdiction depends on the location of the parties or the incident that the lawsuit covers. In essence, it is where a particular lawsuit is originally filed.
Justipedia explains Original Jurisdiction
Original jurisdiction differs from appellate jurisdiction because original jurisdiction is where a case starts. Appellate jurisdiction is where a case will go if there is an appeal made. When there is a dispute between the two courts on a judgment, the state or federal Supreme Court has a power to use original jurisdiction and can hear the case much like a trial court.
