Diversity jurisdiction is a legal concept in the United States that allows federal courts to hear cases involving parties from different states. This is intended to provide a neutral forum and reduce potential bias that might occur in state courts. For a case to qualify, the parties must be citizens of different states, and the amount in controversy must exceed a specified threshold, typically $75,000. This type of jurisdiction is outlined in 28 U.S.C. § 1332, which governs the conditions under which federal courts can take on these cases. Diversity jurisdiction helps ensure fairness in legal proceedings, especially in disputes involving individuals or entities from different regions.
