Civil Procedure · Diversity
Clear answer to: What Is Diversity in Civil Procedure? with key cases, examples, and exam tips for law students.
Diversity in civil procedure refers to the jurisdictional principle that allows federal courts to hear cases where the parties are from different states, aiming to prevent local bias. It requires complete diversity and an amount in controversy exceeding $75,000.
Diversity jurisdiction, rooted in Article III, Section 2 of the U.S. Constitution, aims to provide neutral ground in litigation involving parties from different states. The primary purpose is to minimize the risk of bias that might occur in state courts, where local prejudices could influence juries. Under 28 U.S.C. § 1332, federal courts can gain jurisdiction in diversity cases if the parties are citizens of different states and the amount in controversy exceeds $75,000.
Complete diversity means that no plaintiff can be from the same state as any defendant. If even one plaintiff shares a state of citizenship with any defendant, the federal court lacks jurisdiction based on diversity. For corporations, citizenship is more complex, as they are considered citizens of not only the state in which they are incorporated but also the state where their principal place of business is located.
In addition to the requirements of diversity and amount in controversy, courts also apply the forum defendant rule, which states that a case cannot be removed from state court to federal court based solely on diversity if any of the defendants are citizens of the state in which the action was brought. This rule aims to preserve the plaintiffs' choice of forum when they sue a local defendant.
Jurisdiction can be complicated with additional considerations involving the timing of removal to federal court and the application of supplemental jurisdiction if there are related claims involving parties from the same state. Courts often take a factual and substantive approach to ascertaining jurisdiction, ensuring that the intent of the diversity statute is upheld while allowing for fairness in judicial proceedings.
A resident of California sues a corporation incorporated in Delaware and having its principal place of business in New York for $100,000 in damages. Due to the differing state citizenships and the amount at stake, the federal courts would have diversity jurisdiction to hear the case.
Diversity jurisdiction is frequently tested on law school exams, particularly in issues of jurisdictional specificity, the application of the complete diversity rule, and interpretation of statutory requirements.
