In the event that parties or attorneys conduct themselves in a disrespectful, disorderly or contumacious manner at any hearing, the presiding officer may submit immediately to the commission his report thereon, together with a recommendation.
(2) The presiding officer may, at his discretion, recess or continue any hearing in case the conduct of witnesses, spectators, or other persons interferes with the proper and orderly holding of such hearing or for any other cause or circumstance which may prevent the proper conduct of such hearing.
