Lesson 8: Diversity Jurisdiction

Diversity Jurisdiction is a form of subject matter jurisdiction in federal courts, allowing them to hear cases where the parties are from different states or countries, and the amount in controversy exceeds a specified threshold. This lesson explores the concept, requirements, and implications of diversity jurisdiction, making it both understandable and enjoyable for law students.

Understanding Diversity Jurisdiction

Under 28 U.S.C. ยง 1332, diversity jurisdiction applies when:

  • The parties are "citizens" of different states or one party is a foreign citizen.
  • The amount in controversy exceeds $75,000, exclusive of interest and costs.

Citizenship of the Parties

The concept of citizenship for diversity purposes involves the state of domicile of individuals and the state of incorporation for corporations. Here's a visual representation:

stateDiagram-v2 [*] --> "Parties from Different States" "Parties from Different States" --> "Individual Domicile" "Parties from Different States" --> "Corporate Citizenship" "Corporate Citizenship" --> "State of Incorporation" "Corporate Citizenship" --> "Principal Place of Business"

Amount in Controversy

The amount in controversy must exceed $75,000. This is an important threshold for the federal court to have jurisdiction:

Complete Diversity Requirement

Complete diversity means that no plaintiff shares a state of citizenship with any defendant. Here is a flowchart illustrating this concept:

Implications of Diversity Jurisdiction

Diversity jurisdiction serves to protect out-of-state defendants from potential home-court biases and ensures a neutral federal forum:

  • Neutral Forum: Helps avoid bias against out-of-state parties.
  • Uniformity: Ensures consistent application of federal procedural rules.
  • Strategic Considerations: Parties may prefer federal court for various strategic reasons.

Removal and Remand

In some cases, defendants may seek to remove a case from state court to federal court under diversity jurisdiction. Conversely, plaintiffs may seek remand back to state court:
