Nev. Rev. Stat. § 6.140

In any county, if the district judge for any reason fails or refuses to select a grand jury when required, any interested person resident of the county may apply to the appellate court of competent jurisdiction pursuant to the rules fixed by the Supreme Court pursuant to Section 4 of Article 6 of the Nevada Constitution for an order directing the selection of a grand jury. The application must be supported by affidavits setting forth the true facts as known to the applicant, and the certificate of the county clerk that a grand jury has not been selected within the time fixed or otherwise as the facts may be. The appellate court of competent jurisdiction pursuant to the rules fixed by the Supreme Court shall issue its order, if satisfied that a grand jury should be called, directing the county clerk to select and impanel a grand jury, according to the provisions of NRS 6.110 to 6.132 , inclusive.
