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.
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.
