MattB’s advice is right on the money. But the first thing you need to do, as he says, is make sure you have the numbers. You can’t be the only person who’s embarrassed and appalled by this person so check that you have the support and have a motion added to the agenda of the next EC meeting to vacate the Chair and elect a new chairperson. You would only do this, of course, if you knew who was going to fill the role and who was going to support the move.
By the way, it doesn’t matter how many owners and their proxy votes who got the Chairman elected, it’s one member, one vote on the EC and all it takes is a simple majority to remove the Chir form their office (but not from the committee).
