Arizona Revised Statutes Title 12. Courts and Civil Proceedings § 12-1841. Parties; notice of claim of unconstitutionality

A. When declaratory relief is sought, all persons shall be made parties who have or claim any interest which would be affected by the declaration, and no declaration shall prejudice the rights of persons not parties to the proceeding. In any proceeding that involves the validity of a municipal ordinance or franchise, such municipality shall be made a party and shall be entitled to be heard. In any proceeding in which a state statute, ordinance, franchise or rule is alleged to be unconstitutional, the attorney general and the speaker of the house of representatives and the president of the senate shall be served with a copy of the pleading, motion or document containing the allegation at the same time the other parties in the action are served and shall be entitled to be heard.

B. If a pleading, motion or document containing the allegation is served on the attorney general and the speaker of the house of representatives and the president of the senate pursuant to subsection A, a notice of claim of unconstitutionality shall be attached to the pleading, motion or document as the cover page and shall state the following information:

C. If the attorney general or the speaker of the house of representatives and the president of the senate are not served in a timely manner with notice pursuant to subsection A, on motion by the attorney general, the speaker of the house of representatives or the president of the senate the court shall vacate any finding of unconstitutionality and shall give the attorney general, the speaker of the house of representatives or the president of the senate a reasonable opportunity to prepare and be heard.

D. This section shall not be construed to compel the attorney general, the speaker of the house of representatives or the president of the senate to intervene as a party in any proceeding or to permit them to be named as defendants in a proceeding. The attorney general, the speaker of the house of representatives or the president of the senate, in the party's discretion, may intervene as a party, may file briefs in the matter or may choose not to participate in a proceeding that is subject to the notice requirements of this section.
