I coined the phrase 'professional objector' for an article on planning years ago when it occurred to me that there were a number of local busybodies who objected to everything. I could name them all.

On the matter of SAGs as mentioned by Adam the word authority in this context is not quite accurate - they have of themselves no actual powers but eh various members might. It's another example of a sensible idea gone wrong but what's worse is that there is a real post-code lottery about how officious they can be and even worse they are totally unaccountable to anybody as an entity.

The thing is. If a SAG advises against your event and something goes wrong, then you are really in the soup.

I believe they usually work fairly well with fairgrounds, though COVID has shown a real variance in competence and officiousness.

Rallys, with aging committees often appear at these meetings and get blown away with requirements.
