I have been trying to find an answer to this in Roberts rules, but I have yet to find a definitive path to the correct answer.
I have a Pro tem/ex officio member of my board (he has a voice but no vote outlined in our constitution and bylaws). He is an extremely combative and intimidating person who often turns the meeting upside down when he is there (he does not attend every meeting, nor is he always present for the entire meeting) The Board would like to go into executive session to discuss his behavior and all that surrounds that discussion. Although I do not know the exact numbers, I am confident that a majority of the board members would like to have the session without him in the room. Can we, through Roberts rules, force him to leave the room during the discussion and invite him back in following its completion?
