I'm not sure the consultant should be struck off. It sounds perfectly plausible that she's not mentally ill. It's also possible that in this case, abortion won't fix what she's been sent to her/him about. It shows up the law on abortion as an ass.
However, for me living in England it does throw a light onto the law here. There is something similar about it - you have to have two doctors say your health is at risk, you can't just request an abortion and get one.
