Section 803.06 - Misjoinder and nonjoinder of parties(1) Misjoinder of parties is not ground for dismissal of an action. Parties may be dropped or added by order of the court on motion of any party or on its own initiative at any stage of the action and on such terms as are just. Any claim against a party may be severed and proceeded with separately. Oral argument permitted on motions under this subsection may be heard by telephone under s. 807.13(1).(2) When it comes to the attention of the court that the summons has not been served upon a named defendant, the court may enter an order on its own initiative, after notice to parties of record, dismissing the action as to that defendant without prejudice.Sup.
