Section 20.
The council may adopt rules for the government of its members and its proceedings. It must keep a journal of its proceedings, and on the call of any two of its members, must cause the yeas and nays to be taken and entered upon its journal upon any question before it; but upon a question to adjourn, the yeas and nays shall not be taken, unless upon the call of a majority of the members present. The yeas and nays must always be taken upon a vote on the passage of an ordinance or resolution, and the names of the members voting for and against must be entered upon the journal. Its deliberations and proceedings must be public.
