MBE Civil Procedure: Subject Matter Jurisdiction

An essential overview of subject matter jurisdiction as tested on the MBE, focusing on key principles and application in civil procedure.

Overview

Subject matter jurisdiction refers to the authority of a court to hear a particular type of case. It is a critical aspect of civil procedure, as a court must possess subject matter jurisdiction to adjudicate a dispute. Generally, the two primary sources of subject matter jurisdiction are federal question jurisdiction, which arises from cases concerning federal law, and diversity jurisdiction, which requires parties to be citizens of different states and involves an amount in controversy exceeding $75,000. Understanding these distinctions and requirements is crucial for answering MBE questions accurately.

On the MBE, questions regarding subject matter jurisdiction may address which court has the authority to hear a case, how parties can establish or challenge jurisdiction, and implications of failing to meet jurisdictional requirements. The nuances of supplemental jurisdiction can also appear, as they affect a federal court’s ability to hear additional claims that do not independently satisfy jurisdictional criteria. Candidates must grasp not only the statutory bases for jurisdiction but also the practical consequences of lacking subject matter jurisdiction, as any ruling by a court without such authority is void.

Key Rules
  1. Federal courts have subject matter jurisdiction over federal questions under 28 U.S.C. § 1331.
  2. Diversity jurisdiction exists under 28 U.S.C. § 1332 when parties are from different states and the amount in controversy exceeds $75,000.
  3. Complete diversity is required for diversity jurisdiction; no plaintiff can be from the same state as any defendant.
  4. Supplemental jurisdiction allows federal courts to hear related claims that do not independently satisfy jurisdictional requirements under 28 U.S.C. § 1367.
  5. A plaintiff's claim must establish the existence of subject matter jurisdiction; failure to do so can lead to dismissal.
Common Question Patterns
  • Determining whether a case meets federal question jurisdiction.
  • Assessing whether diversity jurisdiction is satisfied, including citizenship and amount in controversy.
  • Exploring supplemental jurisdiction in multi-claim or multi-party scenarios.
