Arizona Revised Statutes Title 23. Labor § 23-1387. Powers and duties

A. By one or more of its members or by such agents or agencies as it may designate, the board may prosecute any inquiry necessary to its functions in any part of this state. A member of the board who participates in any such inquiry shall not be disqualified from subsequently participating in a decision of the board in the same case.

B. The board shall adopt rules pursuant to title 41, chapter 6  1 as may be necessary to carry out this article.

C. The board may also establish offices in such other cities as it deems necessary and shall determine the region to be served by such offices. The board may delegate to the heads of these offices as it deems appropriate its powers under § 23-1389 to determine the unit appropriate for the purpose of collective bargaining, to investigate and provide for hearings, to determine whether a question of representation exists and to direct an election by a secret ballot and to certify, within a reasonable period of time, the results of such election. The board may review any action taken pursuant to the authority delegated under this subsection by any regional officer on a request for a review of such action filed with the board by any interested party. Any such review made by the board, unless specifically ordered by the board, does not operate as a stay of any action taken by the regional officer. The entire record considered by the board in considering or acting on any such request or review shall be made available to all parties before the consideration or action, and the board's findings and action thereon shall be published as a decision of the board.
