Bit early for panto season );0)
It may well say the PO has the final authority for an agenda but, as we all recognise, that choice (and it obviously is a conscious choice) of words is part of an inexorable creeping course of action by NALC, and readily embraced by empire building / power crazy clerks (others may differ, only applies if cap fits) which, as we so frequently see on these pages, as a consistent source of frustration.
I love it when people cling desperately to a portly or intentionally misinterpreted’regulation’ because it absolutely binds them to abide by ALL regs rather than just the ones they choose.
It may not immediately help if you have a clerk / chair combo that are making a combined fist of it. What you’ll need to do is understand exactly what the regs require, how your council wishes the clerk to perform their duties and then seek to propose suitable amendments - as resolution of the relevant committee or council.
There is plenty of open source guidance on agenda - I seem to recall a NALC document which recommends “consider” “discuss” “resolve” as specific agenda openers.
There is nothing in what NALC or a clerk ‘recommends’ which binds a council to adopt that course of action. The majority of recommendations are pretty logical and un controversial, that line about clerk having final say on agenda is not.
But of course a sensible chair would simply remove ridiculous items from an agenda at the meeting, which they are empowered to do and which pretty much makes a contradiction and a mockery of the misinterpretation that the clerk ‘owns’ the agenda. They don’t.
