Subject-matter jurisdiction
Subject-matter jurisdiction: A court's power to hear a particular type of case. Federal courts can hear only the kinds of cases the Constitution and Congress allow.

What subject-matter jurisdiction means
In short, subject-matter jurisdiction is a term you will meet in court papers, rules and legal research. The definition above gives its usual meaning in American civil practice. However, the exact meaning can depend on the rule, statute or court decision that uses it. So it helps to read the term in context.
Where subject-matter jurisdiction comes up
For example, the term appears in these procedures:
- Motion to Dismiss for Lack of Subject-Matter Jurisdiction (Fed. R. Civ. P. 12(b)(1)): a motion arguing the court has no power to hear this type of case.
How to research the term
Start with the primary source. For example, if subject-matter jurisdiction appears in a federal rule, read the rule itself and its official notes. After that, check your court’s local rules and any standing orders from the judge. In addition, search recent decisions from your own state or federal district. They show how courts read subject-matter jurisdiction in practice. Because state rules often differ, our state procedures guide links to each state’s official rules. Above all, make sure the version you read is still in force.
