The commission in all cases may conduct its proceedings, when not otherwise particularly prescribed by law, in a manner most conducive to the proper dispatch of business and to the ends of justice. A majority of the commission shall constitute a quorum for the transaction of business, but a commissioner shall not participate in any hearing or proceeding in which that commissioner has any direct personal pecuniary interest. The commission from time to time may make or amend such general rules or orders as may be requisite for the orderly regulation of proceedings before it, including forms of notice and the service thereof, which shall conform as nearly as possible to those in use in the courts of this state. Any party may appear before the commission and may be heard in person or by attorney. Every vote and official action of the commission shall be entered of record and its proceedings shall be public upon the request of any person interested. The commission shall have an official seal, which shall be judicially noticed, and every commissioner shall have the right to administer oaths and affirmations in any proceeding pending before the commission. At the beginning of each regularly scheduled meeting of the commission, members must be given the opportunity to participate in a voluntary recitation of the pledge of allegiance.
