What can be done?
There is no obligation upon a council to subscribe to an under or inappropriately performing ALC.
Present your well constructed and empirical argument for un subscribing or non renewal and let the vote prevail.
It is the weakness, apathy or lack of understanding of Cllrs that has allowed the situation where the misinterpretation of intent allows the situation where it is believed that clerks set agenda.
I’ll say it without any reservation - if a PC believes the clerk sets, controls, dictates the agenda, anyone that doesn’t absolutely object to that situation is unfit for the office they hold.
