hrmm, first I heard and deal with a certifier a fair bit, but anything is possible.
I doubt they'll be able to make people with a cert change back though!
I also can't see why they would make it so you can't sort a cert for them, at least this way people are certing a safe change. People will just use dodgey suspension if what ever they have will get them stickerd, if there isnt a safe alternative that can make it legit they'll just go the cheaper/incorrect way..?
