I am concerned that this is a law that was to be used to prosecute child sex offenders and is being used to prosecute a parent who allowed their daughter to have sexual relations with her boyfriend. My understanding is that this is the first time this particular law has been tried. I could be wrong on that.
Anyway, I find it a worrying precedent as the law could also be used for parent of a 16 year old having sex with their 18/19 year old partner/boyfriend/girlfriend. Here in Tas the legal age of consent is 17.
I think the law should be applied in the way it was intended, regardless of any personal feelings about this particular situation.
