My point was about rescinding a previous resolution and this, as you agree, is correct. It is also very clear to me that there is "new" information - a previously undisclosed alternative budget The precept issue is a can of worms and I agree, I see great problems in changing the precept charged with the billing authority once set.
To the OP: The council appears to have other problems which need addressing. I would suggest they could reverse the pay award subject to it not being against employment rules/policies - however another potential minefield. Furthermore, are the clerk's actions in this case correct? Remember you are responsible for the decisions taken, even if you acted in good faith. Also, even if you get the numbers to bring a motion, you need the numbers to carry it. Generally, if you are united as a council such issues can be sorted out going forward, if not be prepared for much frustration!
