But regarding the car accident scenario, it's too arbitrary and bizarre an example. A woman in a state of mind of intentionally wanting to fatally injure her unborn in a car accident would surely qualify for abortion (even in qld) on mental health grounds.
The crux of the issue lies with choice, a woman's right to choice. There is choice on one hand, and crime on the other. A car accident in any situation is deemed either an accident or criminal negligence (drunk driver, speeding..) if its found to be criminal negligence by a third party and one of the victims is an unborn baby then this law would apply. I would assume this also would apply if the mother is the one who causes the accident criminally? Or is it only a thirds party law??
