She would not be suing him. In Australia, you get money, and some other benefits  (free counciling and healthcare) from the government if you are a victim of violent crime. In some cases it can be a substantial amount of money depending on how bad the assult is.   So she is upset that the government wont see her as a victim of violent crime. The people that work with this are working with people who are beaten, raped, and stabbed, or families of murder victims.  I think it is a bit of an insult to them to have to take her seriously.
