What is the primary role of federal courts in the context of exclusive jurisdiction?

The primary role of federal courts, particularly concerning exclusive jurisdiction, is to resolve issues involving federal law and interests. Exclusive jurisdiction means that only federal courts have the authority to hear certain types of cases that fall under federal statutes or constitutional matters. This includes cases involving federal laws, disputes between states, matters involving ambassadors and public ministers, and cases where the United States is a party. By design, this ensures that federal legal issues are decided consistently and uniformly across the country, upholding the integrity of federal law.

In contrast, local disputes would generally fall under the jurisdiction of state courts, as they are often governed by state law. Minor criminal cases, especially those that do not involve significant federal interests, are typically handled in state courts. The issuance of state licenses is another matter that resides with state authorities and not federal courts, further demonstrating the boundaries of federal jurisdiction.
