Without getting into the Constitutional technicalities of the issue (at least not just yet), I suspect this ruling probably reflects the general will of most people. Most of us - myself included - have very little trouble with abortion in the earliest stages of pregnancy. But I think most people also regard killing a healthy, nine-month term fetus as morally indistinguishable from murder, acceptable only when it's the baby's life or the mother's.
Of course, all the news coverage will have extensive sound bites from everyone at the extreme ends of the spectrum on the issue: the religious zealot pro-lifers opposed to abortion at any time, for any reason, and the pro-choicers untroubled by the killing of a baby in the womb while premature babies at earlier stages of development are being saved in the same hospital.
Because screaming and shouting idealogues make for the best TV, don't you know?
