Nev. Rev. Stat. § 678A.530
Before a hearing before the Board, and during a hearing upon reasonable cause shown, the Board shall issue subpoenas and subpoenas duces tecum at the request of a party. All witnesses appearing pursuant to subpoena, other than parties, officers or employees of the State of Nevada or any political subdivision thereof, are entitled to receive fees and mileage in the same amounts and under the same circumstances as provided by law for witnesses in civil actions in the district courts. Witnesses entitled to fees or mileage who attend hearings at points so far removed from their residences as to prohibit return thereto from day to day are entitled, in addition to witness fees and in lieu of mileage, to the per diem compensation for subsistence and transportation authorized for state officers and employees for each day of actual attendance and for each day necessarily occupied in traveling to and from the hearings. Fees, subsistence and transportation expenses must be paid by the party at whose request the witness is subpoenaed. The Board may award as costs the amount of all such expenses to the prevailing party.
