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 of 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.
Miss. R. Civ. P. 21
Advisory Committee Notes
Rule 21 applies, for example, when: (1) the joined parties do not meet the requisites of Rule 20; (2) no relief has been demanded from one or more of the parties joined as defendants; (3) no claim for relief is stated against one or more of the defendants; (4) one of several plaintiffs does not seek any relief against the defendant and is without any real interest in the controversy.
Rules 17 and 19 should be used as reference points for what is meant by nonjoinder in Rule 21. Thus, Rule 21 simply describes the procedural consequences of failing to join a party as required in Rules 17 and 19.
