(1) The commission shall determine its own rules and order of business and shall keep a journal of its proceedings. It may compel the attendance of absent members, may punish its members for disorderly behavior, and, by a vote of not less than two-thirds of its members, may expel a member for disorderly conduct or the repeated violation of its rules. However, a member may not be expelled unless notified of the charge against the member and given an opportunity to be heard.
(2) A majority of the members elected to the commission constitute a quorum to do business, but a less number may adjourn from time to time and compel the attendance of absent members in the manner and under the penalties prescribed by ordinance. The affirmative vote of a majority of the members elected to the commission is necessary to adopt any ordinance, resolution, order, or vote. However, a vote to adjourn or regarding the attendance of absent members may be adopted by a majority of the members present.
