Powers and duties of examiner

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