Rule 29 - Brief of an Amicus Curiae(a) When Permitted. The United States, the State of Nevada, a political subdivision thereof, or an officer or agency of the foregoing entities, or a state, territory, or commonwealth, or a federally recognized tribe may file an amicus brief without the consent of the parties or leave of court. Any other amicus curiae may file a brief only by leave of court granted on motion or at the court's request or if accompanied by written consent of all parties.(b) Motion for Leave to File. A motion for leave to file an amicus brief must be accompanied by the proposed brief and state: (1) the movant's interest; and(2) the reasons why an amicus brief is desirable and why the matters asserted are relevant to the disposition of the case.(c) Contents and Form. An amicus brief must comply with Rule 32. In addition to the requirements of Rule 32, the cover must identify the party or parties supported, if any, and indicate whether the brief supports affirmance, reversal, or extraordinary relief. An amicus brief need not comply with Rule 28, but must include the following:(1) If the amicus curiae is a corporation, a disclosure statement like that required of a party by Rule 26.1.(2) A table of contents, with page references.(3) A table of cases (alphabetically arranged), statutes, and other authorities cited, with references to the pages of the brief where they are cited.(4) A concise statement of the identity of the amicus curiae, its interest in the case, and the source of its authority to file, which does not count toward the type-volume limitation.(5) Unless the amicus curiae is one listed in the first sentence of Rule 29(a), a statement that indicates whether:(A) a party or a party's counsel authored the brief in whole or in part; and(B) any person-other than the amicus curiae, its members, or its counsel-contributed money or other consideration intended to fund preparing or submitting the brief and, if so, identifies each person.(6) An argument, which may be preceded by a summary.(7) An attorney's certificate that complies with the requirements contained in Rule 32(a)(9).(d) Length. Except by the court's permission or as provided in Rule 21(d) as to writ proceedings, an amicus brief may be no more than one-half the maximum length authorized by these Rules for a party's brief. If the court grants a party permission to file a longer brief, that extension does not affect the length of an amicus brief.(e) Time for Filing. An amicus curiae must file its brief, accompanied by a motion for filing when necessary, no later than 7 days after the brief, petition, or answer of the party being supported is filed. An amicus curiae that does not support either party must file its brief no later than 7 days after the appellant's opening brief or the writ petition is filed. The court may grant leave for later filing, specifying the time within which an opposing party may answer.(f) Reply Brief. An amicus curiae may not file a reply brief.(g) Oral Argument. An amicus curiae may file a motion to participate in oral argument, but the court will grant such motions only for extraordinary reasons.(h) During Rehearing, En Banc Reconsideration, and Review by the Supreme Court. The provisions of this Rule apply to amicus briefs submitted in connection with rehearing, en banc reconsideration, and review by the Supreme Court. Such briefs may be filed irrespective of whether an amicus brief was filed by that amicus curiae in the primary briefing. Except by the court's permission, the length of an amicus brief in these proceedings must not exceed 4,667 words.As amended effective 1/20/2015; amended effective 8/15/2024.
