Powers and duties of examiner

The commission by motion may limit the powers and duties of an examiner in a particular case to the issues or performance of acts the commission deems expedient. However, subject only to a limitation ordered by the commission, the examiner to whom a matter or proceeding is referred under this chapter may hold hearings on the matter or proceeding in accordance with and pursuant to this chapter. The examiner shall have the power to regulate proceedings before the examiner and to perform acts and take measures necessary or proper for the efficient and orderly conduct of the hearing, including ruling on prehearing motions, the swearing of witnesses, and receiving of testimony and exhibits offered in evidence, subject to any objections imposed, and shall cause a complete record of the proceedings to be made and retained.
