The gang of three could just as easily say that they are keeping disruptive troublemakers away from the levers of power. In my experience at NCAT, I don’t think NCAT would buy such an argument, because it is subjective and cannot be proved.
That was intended as an example of a response to the excluded members saying – without evidence – that the committee members were being unreasonable. It’s the same argument, based on subjective opinions, not facts.
