No action may be taken by the commission unless a quorum is present. A quorum shall consist of five members. Five affirmative votes shall be necessary to adopt, amend or repeal any rule and regulation of the commission; terminate appointment of an at-large member; and to change the assessment rate. On any other motion before the commission, the concurrence of a majority of those present shall be sufficient.
