As at any meeting, a good Chair has 1st and last say, and it is up to him/her to enforce strict adherence or not to rules. If things are flowing well, no-one dominating, each speaker courteous and making a sensible contribution to the matter being addressed, all should be happy without strict rule adherence. This includes the Chair ensuring each who wants to speak has a turn. Each and every situation must be judged on its own merits and handled appropriately. Unless something has been dealt with previously and a majority decision taken that does not warrant revisiting, I find it is often better to leave my speaking to last then summarise a motion for voting that can be my wording, not the pedant’s. That’s what then makes it into the minutes.
