Witnesses and testimony
(1)The director or any agent, deputy, or administrative law judge may issue subpoenas to compel the attendance of witnesses or parties and the production of books, papers, or records and to administer oaths. Any person who serves a subpoena shall receive the same fee as the sheriff. Each witness who is subpoenaed on behalf of the director and who appears in obedience thereto shall receive for attendance the fees and mileage provided for witnesses in civil cases in the district court, which are audited and paid from the state treasury in the same manner as other expenses are audited and paid, upon the presentation of a proper voucher approved by the director. The director has the discretion to assess the cost of attendance and mileage of witnesses subpoenaed by either party to any proceeding against another party to the proceeding when, in the director’s judgment, the necessity of subpoenaing the witnesses arises out of the raising of any incompetent, irrelevant, or sham issues by the other party.
(2)The director, an agent, deputy, or administrative law judge of the division, or an administrative law judge from the office of administrative courts, may, upon a showing of good cause, order the attendance at a hearing or deposition of any party, or of an officer, director, employee, or agent of any party, who is located in another state. A witness so ordered shall appear as indicated in the order or shall be available by telephone at the time and place set forth in the order.
(3)If a party or an officer, director, employee, or agent of a party fails, in the absence of a reasonable excuse, to obey an order issued pursuant to subsection (2) of this section, the party, officer, director, employee, or agent is liable for penalties as specified in section 8-43-304 (1).
