technically, it was a crime for a minor to get pregnant in the first place. if the law is going to be rigidly interpreted and implemented, then she needs to be questioned about who impregnated her, so he can be charged, and she can technically be charged too, unless it was not consensual.

any laws will be irrelevant anyway unless they are absolutely rigidly enforced. in australia they are so vague, so open to interpretation, that every case is dealt with differently anyway, depending on the unique features of the girl involved and her circumstances. this probably works as well as any other system.

rigidly enforced laws will benefit some, but be harmful to others. better to allow a bit of flexibility in how it all happens, and who is involved.
