The best chance of a meaningful response is to pose a precise and clearly defined question.
As it stands, the only response possible is to point out that it doesn’t really matter what your clerk is “telling” Cllrs.
If the clerk is talking nonsense or, as you seem to intimate, seeks to impose unwelcome process upon a council, the council (or individual Cllrs) are perfectly at liberty to:
(a) ask the clerk to validate their advice with an authoritative reference
(b) acknowledge that the advice is received and understood - and then either adopted / implemented or that it is dismissed
(c) remind the clerk (via the appropriate channels) that they serve not direct the council.
