I enjoy our disagreements about processes but now you're just being silly. So, lets break it down a bit. No councillor, chair or otherwise, has the power to overturn the majority decision of the council. So, if council has resolved to accept the minutes as accurate, so be it. The physical signature simply confirms that at the meeting at which those minutes were accepted, there was a resolution to do so. As it happens, there is, in most standing orders, a mechanism for the chair to indicate concern over the minutes but the original post implies that this is not being used. In any event does it matter? Probably not as the minutes of the later meeting will reflect the decision of the council to accept the minutes whether or not the chair has thrown his or her toys out of the pram and refused to put pen to paper. No doubt, the recording you are fond of advocating will also reflect this.
