Diversity cases require an amount in controversy of more than $75,000.
Federal courts hear cases with federal jurisdiction. Such jurisdiction comes if the case hears a question of federal law or if the case has diversity jurisdiction (parties are citizens of different states and minimum dollar amount is in dispute.)
Federal cases involving citizens of different states are called "diversity" cases if that is the claimed basis for Federal court jurisdiction.
Sometimes either. A civil case may be tried in the state of the party filing suit, or a party can invoke federal diversity jurisdiction and remove the case to federal court if the amount of the claim is in excess of $75,000.
Federal diversity jurisdiction may be invoked in a civil action between citizens of different states if the amount of the claim is in excess of $75,000.
The authority of a court to rule on certain cases is known as the jurisdiction of the court. State courts have jurisdiction over matters within that state, and different levels of courts have jurisdiction over lawsuits involving different amounts of money. Federal courts have jurisdiction over lawsuits between citizens of different states, or cases based on federal statutes.
Federal court jurisdiction depends on the nature of the controversy, not upon who the parties are.
No. A federal court would have no jurisdiction over disputes between individuals that would be considered "small claims." If the dispute were between residents of the same state over a debt, for example, there would be no federal question, therefore no federal jurisdiction. If the dispute were between residents of different states, the federal courts would have diversity of citizenship jurisdiction only if the amount in controversy exceeded $75,000.
Diversity jurisdiction is a basis for federal courts to exercise jurisdiction if the parties to a civil cause of action are residents of different states and the amount in controversy is large enough to make use of federal resources practical. A state may legitimately exercise jurisdiction either if it has in rem jurisdiction over the property or in personam jurisdiction over all parties to the dispute.
Chapter 85 of the Judicial Code, Title 28, United States Code, section 1330, et seq., defines the jurisdiction of the federal courts. The primary types of jurisdiction are: (1) federal-question jurisdiction, 28 U.S.C. §1331, which provides that "[t]he district courts shall have original jurisdiction of all civil actions arising under the Constitution, laws, or treaties of the United States"; and, (2) diversity jurisdiction, 28 U.S.C. §1332, which sets forth generally that citizens of two different U.S. States, as defined in the Judicial Code, who have an amount in controversy exceeding $75,000, can go to federal court. Also read the rest of the Judicial Code, particularly but not limited to removal jurisdiction and supplementary jurisdiction.
Federal diversity jurisdiction (diversity of citizenship) allows citizens of different states to file civil action against each other in federal court (instead of state court) under certain circumstances. Diversity jurisdiction may be invoked for civil cases involving claims in excess of $75,000.
They do not have jurisdiction.
The cases that the federal judiciary have jurisdiction over were disagreements between two or more states and citizens rights to trial by jury.
