SECTION 2.11 PROCEDURE.
   a.   Meetings: The Council shall meet regularly at such times and places as the Council may prescribe by Ordinance. Special meetings may be held on the call of the Mayor or of 3 or more members and, whenever practicable, upon no less than twenty-four (24) hours notice to each member. Except as allowed by state law, all meetings shall be public; however, the Council may recess for the purpose of discussing in a closed or executive session limited to its own membership, legal counsel and other persons invited by the Council, any matter which would tend to defame or prejudice the character or reputation of any person, any matter concerning personnel or collective bargaining matters or any threatened or pending litigation, if the general subject matter for consideration is expressed in the motion calling for such session and final action on such motion is not taken by the Council until the matter is placed on the agenda.
   b.   Rules and Journal: The City Council shall determine its own rules and order of business and shall provide for keeping a journal of its proceedings. This journal shall be a public record.
   c.   Voting: Voting, except on procedural motions, shall be by roll call and the ayes and nays shall be recorded in the journal. Four members of the Council shall constitute a quorum, but a smaller number may adjourn from time to time and may compel the attendance of absent members in the manner and subject to the penalties prescribed by the rules of the Council. No action of the Council, except as otherwise provided in the preceding sentence and in § 2.06, shall be valid or binding unless adopted by the affirmative vote of 4 or more members of the Council.
