Hi there - what a tough situation! In general, anything regarding the group as a whole -- like disbanding -- should be voted on by the whole group, not just the board. As far as a quorum, in general that refers to the number present at a properly called meeting -- again, not just the board.

So if you truly want to disband, I suggest you call a meeting and vote of the larger group.
Good luck. Liz from PTO Today
