Chapter 2 provides a comprehensive overview of the different types of jurisdiction that determine which court system—federal or state—can hear and decide a case. Understanding these types of jurisdiction is crucial for ensuring that cases are filed in the appropriate court.

Federal Question Jurisdiction: Federal question jurisdiction, under 28 U.S.C. § 1331, allows federal courts to hear cases "arising under" federal law, including constitutional issues, federal statutes, and treaties. The "well-pleaded complaint rule" ensures that the federal question is evident from the plaintiff's initial complaint.

Diversity Jurisdiction: Diversity jurisdiction, provided under 28 U.S.C. § 1332, enables federal courts to hear cases where the parties are citizens of different states or countries and the amount in controversy exceeds $75,000. This type of jurisdiction offers a neutral federal forum to mitigate potential state court biases.

Supplemental Jurisdiction: Supplemental jurisdiction, under 28 U.S.C. § 1367, allows federal courts to hear additional claims closely related to those over which they have original jurisdiction. This includes pendent jurisdiction for state law claims related to federal claims and ancillary jurisdiction for necessary claims involving additional parties or issues.

Exclusive vs. Concurrent Jurisdiction:

Removal and Remand:

In this chapter, we delved into the concept of subject matter jurisdiction, exploring the criteria for federal question and diversity jurisdiction, the scope of supplemental jurisdiction, and the principles of exclusive and concurrent jurisdiction. We also covered the procedural aspects of removal and remand, crucial for understanding how cases transition between state and federal courts. These fundamentals of SMJ ensure that cases are heard in the appropriate legal forum, setting the stage for the efficient administration of justice.

This chapter emphasizes the importance of understanding the different types of jurisdiction to ensure that cases are heard in the correct court system, facilitating efficient and fair legal proceedings.
