Remember that any decision of the committee must be made at z committee meeting. None of this voting by email.
And all committee meetings and agendas need to be sent to Owners prior to the meetings.
Thirdly owners always override the decision of a committee with sufficient numbers.
So if you can organise enough owners they can overule the committee.
Failing getting the decision thrown out at the committee meetings, if you get 25% of lot ownersto petition the secretary, you can call a general meeting where you out your motion to reverse the committee decision.
