"If there is a change, as has been suggested, from the current definition in the 2010 Act to a definition based on biological sex, that would create a blanket ban on trans people from services that they had previously enjoyed without concern or complaint, even when it cannot be said to be a proportionate means of achieving a legitimate aim. The change would remove the current protection from discrimination for people in possession of a gender recognition certificate and undermine the Gender Recognition Act, leading to people being treated as if they had not changed their sex.""
