Rule 320 - Permissive Joinder of Parties(a) Permissive Joinder. All persons may join in one action as plaintiffs if they assert any right to relief jointly, severally, or in the alternative in respect of or arising out of the same transaction, occurrence, or series of transactions or occurrences and if any question of law or fact common to all of them will arise in the action. All persons may be joined in one action as defendants if there is asserted against them jointly, severally, or in the alternative, any right to relief in respect of or arising out of the same transaction, occurrence, or series of transactions or occurrences and if any question of law or fact common to all of them will arise in the action. A plaintiff or defendant need not be interested in obtaining or defending against all the relief demanded. Judgment may be given for one or more of the plaintiffs according to their respective rights to relief, and against one or more defendants according to their respective liabilities. (b) Separate Trials. The court may make such orders as will prevent a party from being embarrassed, delayed, or put to expense by the inclusion of a party against whom the party asserts no claim and who asserts no claim against that party, and may order separate trials or make other orders to prevent delay or prejudice. (c) Parties Jointly or Severally Liable. Persons jointly or severally liable upon the same obligation or instrument, including the parties to negotiable instruments and sureties on the same or separate instruments, may all or any of them be sued in the same action, at the option of the plaintiff. (b) amended July 22, 1993, effective 1/1/1994.
