I think it's astonishing that a 15 year old is not considered to have capacity to make choices about her own body tbh. It's very worrying what that teaches her about rights over her own body.
I hate the way so many people say both parents are at fault for it getting to court - just because something has ended up in court, doesn't mean it is because both parents are unreasonable, it could be because one of them is terribly unreasonable and insists on taking the other reasonable parent to court maliciously, or that the one who is taken to court is so unreasonable that the other parent feels they really have no option but to do that, or that both of them are perfectly reasonable people with very strongly held beliefs who find that there is no other way of settling it than court.
Unreasonable people exist. Sometimes reasonable people marry them and reproduce with them. When the shit hits the fan, it's not necessarily because one or both of them are unreasonable.
(Disclaimer: I've never been taken to court or taken anyone to court, so I don't have an axe to grind on this issue, I just can't stand the automatic assumption that court = loons.)
