Summary

Federal district courts must also hear other claims that are closely related to a case they already have. If the extra claims are part of the same dispute, the court can decide them too. That includes claims that add new parties or let people join or intervene. But when a case is based only on diversity under section 1332, the court cannot use this rule to allow certain new plaintiff claims or claims against new parties added under Rules 14, 19, 20, or 24 if doing so would break the rules of section 1332. The court can also refuse to hear an extra claim if it raises a new or hard state-law issue, if it mostly replaces the federal claim, if the federal claims are gone, or for other rare strong reasons. The time limit for a claim covered this way is paused while the claim is pending and for 30 days after it is dismissed, unless the state law gives a longer pause. The word “State” here includes the District of Columbia, the Commonwealth of Puerto Rico, and any U.S. territory or possession.

Title 28, §1367

Judiciary and Judicial Procedure, Source: USLM XML via OLRC

(a)Except as provided in subsections (b) and (c) or as expressly provided otherwise by Federal statute, in any civil action of which the district courts have original jurisdiction, the district courts shall have supplemental jurisdiction over all other claims that are so related to claims in the action within such original jurisdiction that they form part of the same case or controversy under Article III of the United States Constitution. Such supplemental jurisdiction shall include claims that involve the joinder or intervention of additional parties.
(b)In any civil action of which the district courts have original jurisdiction founded solely on section 1332 of this title, the district courts shall not have supplemental jurisdiction under subsection (a) over claims by plaintiffs against persons made parties under Rule 14, 19, 20, or 24 of the Federal Rules of Civil Procedure, or over claims by persons proposed to be joined as plaintiffs under Rule 19 of such rules, or seeking to intervene as plaintiffs under Rule 24 of such rules, when exercising supplemental jurisdiction over such claims would be inconsistent with the jurisdictional requirements of section 1332.
(c)The district courts may decline to exercise supplemental jurisdiction over a claim under subsection (a) if—
(1)the claim raises a novel or complex issue of State law,
(2)the claim substantially predominates over the claim or claims over which the district court has original jurisdiction,
(3)the district court has dismissed all claims over which it has original jurisdiction, or
(4)in exceptional circumstances, there are other compelling reasons for declining jurisdiction.
(d)The period of limitations for any claim asserted under subsection (a), and for any other claim in the same action that is voluntarily dismissed at the same time as or after the dismissal of the claim under subsection (a), shall be tolled while the claim is pending and for a period of 30 days after it is dismissed unless State law provides for a longer tolling period.
(e)As used in this section, the term “State” includes the District of Columbia, the Commonwealth of Puerto Rico, and any territory or possession of the United States.
