Rule 24 – Intervention

May 13, 2021 | Civil Procedure, Mississippi

(a) Intervention of Right. Upon timely application, anyone shall be permitted to intervene in an action:

(1) when a statute confers an unconditional right to intervene; or
(2) when the applicant claims an interest relating to the property or transaction which is the subject of the action and he is so situated that the disposition of the action may as a practical matter impair or impede his ability to protect that interest, unless the applicant’s interest is adequately represented by existing parties.
(b) Permissive Intervention. Upon timely application anyone may be permitted to intervene in an action:

(1) when a statute confers a conditional right to intervene; or
(2) when an applicant’s claim or defense and the main action have a question of law or fact in common.

When a party to an action relies for ground of claim or defense upon any statute or executive order administered by a federal or state governmental officer or agency, or upon any regulation, order, requirement, or agreement issued or made pursuant to the statute or executive order, the officer or agency upon timely application may be permitted to intervene in the action. In exercising its discretion the court shall consider whether the intervention will unduly delay or prejudice the adjudication of the rights of the original parties.

(c) Procedure. A person desiring to intervene shall serve a motion to intervene upon the parties as provided in Rule 5. The motion shall state the grounds therefor and shall be accompanied by a pleading setting forth the claim or defense for which intervention is sought. The same procedure shall be followed when a statute gives a right to intervene.
(d) Intervention by the State. In any action (1) to restrain or enjoin the enforcement, operation, or execution of any statute of the State of Mississippi by restraining or enjoining the action of any officer of the State or any political subdivision thereof, or the action of any agency, board, or commission acting under state law, in which a claim is asserted that the statute under which the action sought to be restrained or enjoined is to be taken is unconstitutional, or (2) for declaratory relief brought pursuant to Rule 57 in which a declaration or adjudication of the unconstitutionality of any statute of the State of Mississippi is among the relief requested, the party asserting the unconstitutionality of the statute shall notify the Attorney General of the State of Mississippi within such time as to afford him an opportunity to intervene and argue the question of constitutionality.

Miss. R. Civ. P. 24

Advisory Committee Notes

Rule 24 requires the court to balance the interests of the would-be intervenor against the burdens such intervention might pose on those already parties or on the judicial system’s economic and efficient disposition of the case. If one of the criteria for intervention as a matter of right is met and the would-be intervenor files a timely application for intervention, intervention shall be allowed. See Dare v. Stoke, 62 So. 3d 958, 959 (Miss. 2011). A trial court has discretion when ruling on a timely motion to permissively intervene and “may permissively grant or deny a motion to intervene, provided there is a common question of law or fact and the motion was timely filed.” See Madison HMA, Inc. v. St. Dominic-Jackson Mem’l Hosp., 35 So. 3d 1209, 1215 (Miss. 2010).

Applications to intervene as of right pursuant to Rule 24(a) or to permissively intervene pursuant to Rule 24(b) must be timely. The rule does not set out any specific time limits. Instead, trial courts are to weigh the following four factors when determining timeliness: “(1) the length of time during which the would-be intervenor actually knew or should have known of his interest in the case before he petitioned for leave to intervene; (2) the extent of the prejudice that the existing parties to the litigation may suffer as a result of the would-be intervenor’s failure to apply for intervention as soon as he actually knew or reasonably should have known of his interest in the case; (3) the extent of the prejudice that the would-be intervenor may suffer if his petition for leave to intervene is denied; and (4) the existence of unusual circumstances mitigating either for or against a determination that the application is timely.” See Hood ex rel. State Tobacco Litigation, 958 So. 2d 790, 806 (Miss. 2007). The determination of whether an application to intervene is timely is committed to the discretion of the trial court and will not be overturned on appeal absent an abuse of discretion.
