For those who were wondering if a council member has to vote the answer is yes they do according to this section in the charter.
Section 6.9. Rules of Order.
The Council shall determine its own rules and order of business and shall keep a written or printed journal of all its proceedings in the English language which shall be signed by the Chairman of the Council and the City Clerk. The vote upon the passage of all ordinances, and upon the adoption of all resolutions shall be taken by “YES” and “NO” votes and entered upon the record except that where the vote is unanimous, it shall only be necessary to so state. An affirmative vote of the majority of the quorum of the Council is necessary to validate any resolution. Each member of the Council, who shall be recorded as present, shall vote on all questions decided by the Council unless excused by the unanimous consent of the members present, but no Councilman shall vote on any question in which he has any financial interest other than the common public interest.
State law references: Mandatory that Charter provide for keeping of a journal, MCL 117.3(m),; conflicts of interest as to contracts, MCL 15.321 et seq.; standards of conduct and ethics, MCL 15.341 et seq.; freedom of information act, MCL 15.231 et seq.
This was brought up at the last city council meeting when councilman Ned Apigian said that he was not going to vote for any of the candidates for the clerk’s position.
