I quite agree that solicitors should never have been allowed to advertise, and indeed the 20 partner limit should still be in place and it should be illegal to form professions into limited companies so that professionals can try to escape their own negligence. Additionally, solicitors' insurance should only kick in to protect the client if the solicitor goes bankrupt on the claim. Same should apply to accountants and auditors too.

If your reference to restrictive clauses means you like will writers and licensed conveyancers, I will repeat what I've said before that I've never picked up a piece of work by either that did not contain at least one egregious goof.
