Lesson 6: Subject Matter Jurisdiction

Welcome to Lesson 6 of our jurisdiction series. In this lesson, we will delve into the concept of Subject Matter Jurisdiction—a critical element in civil procedure.

Subject Matter Jurisdiction refers to the court's authority to hear a particular type of case. This jurisdiction is granted by the constitution or statute and is essential for a court to have the power to adjudicate the matter. Without it, any decision made by the court is invalid.

Here's a simple representation of the types of jurisdiction:

Key Principles of Subject Matter Jurisdiction

Subject Matter Jurisdiction is guided by certain fundamental principles:

  • Exclusivity: Some matters can only be heard in federal courts, while others are reserved for state courts. For example, bankruptcy cases are exclusively federal.
  • Concurrent Jurisdiction: Some cases can be heard in both federal and state courts. An example is cases involving federal questions and diversity jurisdiction.

For a deeper understanding, refer to Wikipedia's entry on Subject Matter Jurisdiction.

Federal vs. State Subject Matter Jurisdiction

Federal courts have limited jurisdiction, meaning they can only hear cases authorized by the U.S. Constitution or federal statutes. State courts, on the other hand, have general jurisdiction and can hear a broader range of cases.

For practical applications, consider exploring the differences between Federal vs. State Jurisdiction.

Case Examples

Let's look at some examples to illustrate subject matter jurisdiction:

  • A case involving a federal statute such as the Americans with Disabilities Act (ADA) falls under federal question jurisdiction.
  • A case where the parties are from different states and the amount in controversy exceeds $75,000 falls under diversity jurisdiction.
  • A case involving state law, such as a contract dispute between residents of the same state, is typically heard in state courts.

Mathematical Representation of Diversity Jurisdiction

In the context of Diversity Jurisdiction, mathematically it can be represented as:

AIC > 75000

Challenging Subject Matter Jurisdiction

If a party believes that the court lacks subject matter jurisdiction, they can file a motion to dismiss the case. This challenge can be raised at any time during the proceedings.
