I did pick up on that, and that also is not proper here either as board members are generally selected by the membership, unless it is a nonprofit without members in which case this is open season for a cat-fight of enormous magnitude.
OTOH, if they had breached their fiduciary duties and she therefore told them their presence was no longer welcome, they have an option. They can go to court for an order invalidating corporate actions in their absence and restoring their positions on the board. But their improper actions would come to light in court.
Sounds like a mess to me.
Is the chairman/president himself capable of unilaterally telling members that they have breached their fiduciary duties? Up here, I am fairly sure that it would have to be a majority of the board itself.
BTW—I appreciate your post. For the most part, this thread has become a catfight of enormous magnitude. I wish it would get pulled from breaking.
