Which of the following is true regarding supplemental jurisdiction?

Supplemental jurisdiction is a legal doctrine that allows federal courts to hear additional claims that are not independently within their jurisdiction, provided those claims are related to the claims that do fall within federal jurisdiction. This is essential for promoting judicial efficiency and conserving resources by allowing related claims to be resolved in a single trial.

Choosing the option that states supplemental jurisdiction is used to manage related claims in the same trial accurately reflects its fundamental purpose. When a federal court has original jurisdiction over a claim, it can exercise supplemental jurisdiction over additional claims that arise from the same nucleus of operative fact, thus enabling the court to address multiple issues in a single proceeding rather than requiring separate lawsuits. This principle helps prevent the risk of inconsistent judgments that might arise if separate courts were to handle different parts of the same case.

For instance, saying it allows federal courts to hear state law claims without limits overlooks the fact that such claims must still be closely tied to the federal claims at hand. Likewise, stating that it permits incorporation of unrelated claims would mischaracterize the necessity for the claims to have a relatedness to the original federal claim. Lastly, the assertion that it only applies to cases with a federal defendant is incorrect; supplemental jurisdiction can also apply
