The commission shall hold regular public meetings at a regular hour to be fixed by ordinance of said commission. It may hold such adjourned, called, special, or other meetings as the business of the city may require. The mayor when present, shall preside at all meetings of said commission. A majority of the commission members elected shall constitute a quorum for the transaction of any and every power conferred upon said commission, and affirmative vote of a majority of those members present shall be sufficient for the passage of any resolution, bylaw, or ordinance, or the transaction of any business of any sort by the said commission or the exercise of any of the powers conferred upon it by the terms of this chapter or by law, or which may hereafter be conferred upon it. No resolution, bylaw, or ordinance granting any franchise, appropriating any money for any purpose, providing for any public improvements, any regulation concerning the public health, or of any other general or permanent nature, except the proclamation of quarantine, shall be enacted except at a regular public meeting of said commission or an adjournment thereof. Every ordinance introduced at any and every such meeting shall be in writing before any vote thereon shall be taken, and the yeas and nays thereon shall be recorded; provided that if the vote of all commissioners present be unanimous, it may be so stated in the journal without recording the yeas and nays. A record of the proceedings of every meeting of the commission shall be kept, and every resolution or ordinance passed by the commission must be recorded and the record of the proceedings of the meeting shall, when approved by the commission be signed by the mayor and the city clerk. Such record shall be kept available for inspection by all citizens of such city at reasonable times. No ordinance of permanent operation shall be passed at the meeting at which it was introduced except by unanimous consent of all members of the commission present, and such unanimous consent shall be shown by the yea and nay votes entered upon the minutes of said meeting, provided, however, that if all members of the commission present vote for the passage of the ordinance and their names are so entered of record as voting in favor thereof, it shall be construed as giving unanimous consent to the action upon such ordinance at the meeting at which it is introduced. Publication of ordinances shall be governed by Section 11-45-8, as amended, Act No. 87-668.
