If a bishop ordained a man without getting the proper approval, that would be an illicit ordaination. Some people have said this is an invalid ordaination, but I would go a step further and say it isn't even that. If a bishop did an ordaination, without following the requisite form to make it valid, that would be invalid. In this case, someone (I don't think it mentions who) pretended to ordain this woman. Since it's not clear whether the person was a bishop, who knows if it would have been valid, even if it was a man. This is no more an ordaination than if a lay person had attempted to perform the ordaination. (BTW, it wouldn't be valid if a nonbishop priest had done it, except that some people mught dispute that. Luwig Ott cites cases where a priest ordains another priest, but in those cases the priest is likely a bishop as well. There doesn't seem to be any reliable evidence for ordainations done by priests)
