Title 28 › PART IV — JURISDICTION AND VENUE › CHAPTER 85 — DISTRICT COURTS; JURISDICTION › § 1367
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.
