OK, although there is nothing to stop the council from changing its standing orders. But if that is an obstacle, then Old Tom's answer is the way to go. Some clerks do tend to be obstinate, but as Old Tom says, the clerk is employed by the council. Although it would be right for a clerk to resist a council acting unlawfully or recklessly, there is no justification for being obstructive. As with any employment, there should be periodic reviews, and any problems should be raised and documented.
