(1) is given an unconditional right to intervene by a 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) Procedure. 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.

On timely motion, the court must permit the attorney general to intervene on behalf of the state.
