Introduction to the Hanna v. Plumer Two-Part Test
The Hanna v. Plumer two-part test is a legal precedent established by the Supreme Court to determine whether a federal court has jurisdiction over a state law claim. This test is crucial in civil procedure, as it helps to clarify the boundaries between federal and state courts.
The two-part test was first introduced in the 1965 case of Hanna v. Plumer, where the Supreme Court ruled that a federal court may exercise jurisdiction over a state law claim if the claim arises under federal law or if the court has diversity jurisdiction.
The First Part of the Test: Federal Question Jurisdiction
The first part of the Hanna v. Plumer test examines whether the state law claim arises under federal law. This means that the claim must be based on a federal statute or the Constitution, and the federal issue must be substantial and actually disputed.
If the claim meets this criteria, the federal court may exercise jurisdiction over the claim, even if the claim is based on state law. This is because federal courts have the authority to interpret and apply federal law, and the claim is therefore within their jurisdiction.
The Second Part of the Test: Diversity Jurisdiction
The second part of the test considers whether the court has diversity jurisdiction over the claim. Diversity jurisdiction allows a federal court to hear a case between citizens of different states, as long as the amount in controversy exceeds a certain threshold.
In the context of the Hanna v. Plumer test, diversity jurisdiction is relevant because it provides an alternative basis for federal jurisdiction, even if the claim does not arise under federal law. If the court has diversity jurisdiction, it may exercise jurisdiction over the claim, regardless of whether it arises under federal law.
