2. Federal Question Suits
A federal question suit is one arising under the Constitution, laws, or treaties of the United States. In general, the reason there is a federal question is that federal law is the source of the plaintiff’s claim.
3. Supplemental Jurisdiction
Under the doctrine of supplemental jurisdiction, if a basic controversy satisfies federal subject matter jurisdictional requirements, additional claims and additional parties may be brought into the litigation.
Under the doctrine of removal, any action brought in state court which the plaintiff could have brought in federal court may be transferred, or removed by the defendant to federal district court. But, it is important to note in diversity suits that the action may be removed only if no defendant is a citizen of the state in which the action is pending.
