What is Supplemental Jurisdiction? A Comprehensive Overview

Definition & Meaning

Supplemental jurisdiction refers to the ability of U.S. federal courts to hear additional claims that are closely related to an original claim, even if the court does not have the authority to hear those additional claims on their own. This legal principle allows courts to manage cases more efficiently by resolving interconnected issues in one proceeding. Supplemental jurisdiction has been part of federal law since 1990 and encompasses both ancillary claims (related to the original claim) and pendent claims (arising from the same set of facts as the original claim).

Real-world examples

Here are a couple of examples of abatement:

Example 1: A plaintiff files a lawsuit in federal court for breach of contract against a defendant. During the proceedings, the plaintiff realizes they also have a related claim for fraud based on the same facts. The court can hear both claims under supplemental jurisdiction.

Example 2: A person sues a company for personal injuries in federal court. They may also want to include claims for emotional distress that arise from the same incident. The court can consider these additional claims together. (hypothetical example)
