Supplemental Jurisdiction Study Outline

A comprehensive outline detailing the principles and rules governing supplemental jurisdiction in federal court, including statutory provisions and key case law.

Overview of Supplemental Jurisdiction

Supplemental jurisdiction is governed by 28 U.S.C. § 1367, which allows federal courts to hear additional claims that are not independently within their original jurisdiction. This provision aims to promote judicial efficiency by allowing related claims to be resolved in one proceeding, rather than fragmenting litigation across different courts. The fundamental requirement is that the supplemental claim must have a common nucleus of operative fact with the original claims that invoke federal jurisdiction.

There are two types of supplemental jurisdiction: (1) claims that are joined as part of the original action under § 1367(a) and (2) claims that arise from the same transaction or occurrence but involve parties who were not originally part of the suit. Common examples include counterclaims, cross-claims, and third-party claims. The court has discretion in exercising supplemental jurisdiction and may decline to hear such claims under specific circumstances outlined in § 1367(c).

Key Rules

  • 28 U.S.C. § 1367(a) - grants supplemental jurisdiction over claims related to the original action.
  • 28 U.S.C. § 1367(b) - limits supplemental jurisdiction in diversity cases to prevent circumventing the amount in controversy requirement.
Limitations and Discretionary Factors

Despite the broad grant of supplemental jurisdiction under § 1367, certain limitations exist. According to § 1367(b), when supplemental jurisdiction is asserted in cases based on diversity of citizenship, courts may not exercise jurisdiction over claims by plaintiffs against parties joined under Rule 14, 19, 20, or 24, if doing so would violate the requirements for diversity jurisdiction. This provision prevents a plaintiff from defeating diversity through the addition of parties which would destroy diversity.

Additionally, § 1367(c) outlines factors under which a court may decline to exercise supplemental jurisdiction, including (1) the claim raising a novel or complex issue of state law, (2) the claim substantially predominating over the claims that invoked original jurisdiction, (3) the district court has dismissed all claims over which it had original jurisdiction, or (4) in exceptional circumstances, there are other compelling reasons for declining jurisdiction. Courts employ a balancing test when determining whether to decline jurisdiction, considering factors such as judicial economy, convenience, and fairness to the parties.

Key Rules

  • 28 U.S.C. § 1367(c) - provides courts with discretion to decline supplemental jurisdiction.
  • 28 U.S.C. § 1367(b) - restricts supplemental jurisdiction in diversity cases.
