How later courts describe this case

  • holding that diversity jurisdiction is assessed as of the time at which the suit is filed
  • holding that later addition of nondiverse plaintiff did not destroy diversity jurisdiction if it was present when action was commenced
  • holding that substitution of non-diverse defendant under Rule 25 did not destroy diversity jurisdiction
  • noting that “[w]e have consistently held that if jurisdiction exists at the time an action is commenced, such jurisdiction may not be divested by subsequent events”
  • stating that in a removed case, “it is clear the relevant time period for determining the existence of complete diversity is the time of the filing of the complaint” in state court
  • using this reasoning to support the rule that diversity jurisdiction, once established, is not defeated by the addition of a non-diverse party
  • “[N]othing in Carden suggests any change in the well-established rule that diversity of citizenship is assessed at the time the action is filed.”
  • noting the Supreme Court has “consistently held that if jurisdiction exists at the time an action is commenced, such jurisdiction may not be divested by subsequent events”
