(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 the applicant is so situated that the disposition of the action may as a practical matter impair or impede the applicant's 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 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 or, if the motion is filed through electronic filing as defined in Rule 2 of the Maine Rules of Electronic Court Systems, as provided in Rule 36 of the of the Maine Rules of Electronic Court Systems. 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. (d) Intervention by the State. When the constitutionality of an act of the legislature affecting the public interest is drawn in question in any action to which the State of Maine or an officer, agency, or employee thereof is not a party, the plaintiff shall notify the Attorney General, and the court shall permit the State of Maine to intervene for presentation of evidence, if evidence is otherwise admissible in the case, and for argument on the question of constitutionality.
