Earlier this year when Bob Correia joined this School Committee, the committee members had a discussion at their regular meeting about Robert's Rules of Order and agreed that they would use that source as guiding in their parliamentary procedures.
At a recent School Committee meeting, Kevin Aguiar tried to make an amendment to a motion using Robert's Rules of Order. Bob didn't appear to like this, as it would have delayed something he was trying to push through - this is when Bob decided to change the rules to use "tradition" rather than the previously agreed upon Robert's Rules of Order "because that is the prerogative of the chair." This is clear and egregious evidence that Bob changes the rules as he goes to favor his position.
