It doesn't really matter, because it will be an adjudicator who decides what statutory ground applies if accepting your case. Essentially the council have, in their stupidity, made it dangerous to carry our a U-turn that avoids passing prohibition signs. Cardiff now, is a complete Dog's Breakfast, but the problem is the more incompetent and stupid the council are, the more money they make ! Stuff like this surely goes a long way to explaining why more and more people are voting for a "certain party" !
