Should any member of the city council refuse or neglect to attend any meeting of the city council, when notified by the marshal or other proper officer that his attendance is necessary to form a quorum (unless he shall present an excuse satisfactory to the city council at its next regular meeting), or should any member leave the city council when in session, without the consent of the city council, when such leaving would break the quorum, he shall be guilty of a misdemeanor and, upon conviction thereof, he may be fined in any sum not exceeding fifty dollars ($50.00). (Prior code § 1-1-10)
