Which type of jurisdiction allows Arizona courts to hear cases involving parties from different states?

Diversity jurisdiction is a specific type of authority that allows federal courts to hear cases involving parties from different states, as long as the amount in controversy exceeds a certain threshold. However, the context of the question refers to Arizona courts, which may not typically operate under the same jurisdictional rules as federal courts.

In the context of state courts, including those in Arizona, diversity jurisdiction can also be relevant as it permits state courts to adjudicate cases between parties from different states, particularly when there is a compelling interest in maintaining neutral ground for disputes that cross state lines.

This distinction is important, as original jurisdiction refers to a court's power to hear a case for the first time, appellate jurisdiction concerns the authority to review decisions made by lower courts, and concurrent jurisdiction means that more than one court can hear a case. Diversity jurisdiction specifically pertains to the ability of courts, including Arizona's, to decide cases involving litigants from different states, emphasizing the necessity of impartiality in cross-state legal matters.
