Wyo. R. Civ. P. 24 (2026)

Rule 24. Intervention. (a) Intervention of Right. — On timely motion, the court must permit anyone to intervene who: (1) is given an unconditional right to intervene by statute; or (2) claims an interest relating to the property or transaction that is the subject of the action, and is so situated that disposing of the action may as a practical matter impair or impede the movant’s ability to protect its interest, unless existing parties adequately represent that interest. (b) Permissive Intervention. — (1) In General. — On timely motion, the court may permit anyone to intervene who: (A) is given a conditional right to intervene by statute; or (B) has a claim or defense that shares with the main action a common question of law or fact. (2) By a Government Officer or Agency. — On timely motion, the court may permit a federal or state governmental officer or agency to intervene if a party’s claim or defense is based on: (A) a statute or executive order administered by the officer or agency; or (B) any regulation, order, requirement, or agreement issued or made under the statute or executive order. (3) Delay or Prejudice. — In exercising its discretion, the court must consider whether the intervention will unduly delay or prejudice the adjudication of the original parties’ rights. (c) Notice and Pleading Required. — A motion to intervene must be served on the parties as provided in Rule 5. The motion must state the grounds for intervention and be accompanied by a pleading that sets out the claim or defense for which intervention is sought.
