In #62, page 650, RONR 11th edition, the section is named: “Removal from Office and other remedies for Dereliction of Duty in Office or Misconduct,” there is a new section that shows the procedure of how to remove a presiding officer from the chair for all or part of a session. If the person presiding is an appointed or elected chairman pro tem, a member can make the motion to “declare the chair vacant and proceed to elect a new chairman.” RONR states this is a question of privilege and is an incidental main motion requiring a majority vote for its adoption. Once the motion is seconded the chairman is required to state the motion to the assembly, then step down from presiding. The secretary takes his place and takes the vote. If the motion is adopted, then the chairman steps down and the members elect another new chairman pro tem. The secretary presides until a new chairman is elected.
