Read the whole post. It's more than this though. It's utilizing any possible pretext to exert control, including that of the health of trees. I'd like to say "total prats", except that this was a quite cynical move on their part.
This tells me that English common law worked exactly as it is supposed to. What we have here is the law working as intended yet a quango wants to impose regulation and inspection to solve a problem that does not need solving because, frankly, it does not exist.
Pity the trees and pity us.
