Which type of jurisdiction requires the amount in controversy to exceed a specific threshold?

Diversity jurisdiction is a type of subject matter jurisdiction that allows a federal court to hear a case when the parties are citizens of different states, and the amount in controversy exceeds a specific threshold, which is currently set at $75,000. This requirement is established by 28 U.S.C. § 1332. The purpose of this threshold is to prevent federal courts from being burdened with cases that do not involve significant amounts of money, ensuring that only those disputes with a substantial economic stake or broader implications are heard at the federal level.

In contrast, personal jurisdiction relates to the court's authority over the parties involved based on their connections to the forum state, rather than the specifics of the case's value. Subject matter jurisdiction as a broader category includes both diversity jurisdiction and federal question jurisdiction, but the specific monetary threshold applies distinctly to diversity jurisdiction. Long-arm jurisdiction refers to a state's ability to assert personal jurisdiction over out-of-state defendants based on their actions that connect them to the state, which does not involve a monetary threshold.
