This is intentional, to secure leadership positions and prevent challenges from below. 

Our goals are to remove the members (already had one vote, which the two board members that needed to go somehow were reelected by 3 votes, and we have heard they paid off people to vote for them), prevent them from further unauthorized spending (we do have a big, reputable management company that handles the money), and press charges for the legal side.

Thanks for response but is there anything I can do to prevent the redemption or is it a done deal and I have to respond with a redemption amount
