One wonders whether the person concerned has legal capacity to, in the first instance nominate herself to stand, and in the second instance if she were to be nominated by someone else whether she would have capacity to accept the nomination. If she attends and votes at meetings and she is the person that makes quorum but due to the dementia is subsequently found not to have legal capacity at the time of the meeting it raises a point as to whether any of the motions or resolutions of the committee are valid.
