576: Law Every 1L Should Know -- Subject Matter Jurisdiction (Civil Procedure)

So let's orient first.

You already have the civil procedure map from the personal jurisdiction episode, so this is short.

A court needs power over two different things.

Personal jurisdiction is the court's power over the defendant.

Subject matter jurisdiction is the court's power over the type of case.

Is this the kind of dispute this court is allowed to decide at all? State courts can hear almost anything.

Federal courts are courts of limited jurisdiction.

They hear only the categories the Constitution and Congress have handed them.

And here is the single most important difference between the two kinds of jurisdiction.

Personal jurisdiction is the defendant's right, so the defendant can waive it.

Subject matter jurisdiction is a limit on the court's own power, so nobody can waive it.

The parties can't consent to it, and a lack of it can be raised by anyone, including the judge, at any time, even on appeal.

So hold on to that, because it matters for the fact pattern.

So let's talk about the two doors into federal court.

The first door is federal question jurisdiction under 28 U.S.C.

Section 1331.

Jurisdiction over all civil actions arising under the Constitution, laws, or treaties of the United States.

The core idea, if federal law creates the plaintiff's claim, the claim arises under federal law.

A suit under a federal civil rights statute is the classic example, and the vast majority of federal question cases look like that.

The rule that does the real work is the well-pleaded complaint rule.

The federal question has to appear on the face of the plaintiff's own properly pleaded complaint in the plaintiff's statement of the plaintiff's own claim, not in a defense, not in a counterclaim.

So if a plaintiff sues on a state law claim and the defendant plans to argue that federal law preempts it, meaning federal law overrides the state law and knocks the claim out, that federal defense does not create federal question jurisdiction.

However, obviously the case will turn on federal law.

Same for a federal counterclaim.

The court looks only at what the plaintiff is suing on.
