Question

can town clerk overturn a decision taken at a full council meeting when all councillors have agreed that decision?

Answer 1

If your clerk has discovered the decision is not legal, or not possible, or has other problems, then they should bring it back to council to be reconsidered.  I don't think they can overturn it - they need another decision by council.  If there is nothing wrong other than the fact that the clerk does not to want to do it, then you may discover that the clerk is more powerful than the council.  A decision that is not liked can very easily be never implemented. Clawing back power to the council requires a robust HR committee and regular appraisals with clear objectives for the clerk. Minutes should record the exact wording of every decision rather than the clerk's interpretation of it. All decisions should state who is to action it and by when and include a process for regular reporting back on progress. To achieve this requires a majority of councilors to recognise the problem and want to do something about it.
