I have always taken the same view, but I wonder whether Model Standing Order 4d viii is intended to give the council the power to determine who should be included in the quorum (as opposed to a simple number) according to local circumstance? I am unable to find a legislative reference to this at present, but in the case of an advisory committee of all (or all but one or two) non-councillors, it would be necessary to count the non-councillors in the quorum, even if they do not have the right to vote.
