This is not a popular view and I'll probably be roasted for saying it here (I have before), but the difficulty with the case of Savita Halappanavar is that, no matter how many times people say it, and how many people believe it, it wasn't Irish law that caused her to die, it was (a) the (wrong) interpretation of that law and (b) utterly appalling and neglectful medical treatment.
The hospital completely missed the symptoms of sepsis, there were unacceptable delays with her test results, and as a patient she was ignored. I suspect she was ignored by medical staff because she was pregnant, but that is no excuse for the lack of medical care. Since she died the entire protocol around sepsis has been changed, in every hospital in the country.
She should have been treated earlier. Under Irish law she could have, and indeed should have, received appropriate treatment for her illness (sepsis) - including removal of foetal tissue as the source of the infection - and that treatment would most likely have saved her life.
Under Irish law women have frequently been treated even if that treatment caused the incidental death of the foetus. What hasn't been legal is the deliberate "killing" of the foetus. To many Irish doctors there is a massive difference, even if the end result (death of the foetus) is the same.
There are doctors here concerned that if this referendum goes through they and other medical staff will be forced to carry out abortions against their wishes. Many of them want some sort of protection for staff who don't want to be involved on conscientious grounds.
I don't happen to agree with many of their statements, but I do believe they have some valid concerns and should, like everyone else, be listened to. I hate the fact that this debate is so polarised. I am pro-choice, absolutely, but I also believe that forcing medical staff to perform treatments that they believe is morally wrong isn't an acceptable way to do this.
For this referendum to go through, I think it's important that the "yes" side don't dismiss concerns that are relevant; again the need is to appeal to the middle-ground undecided. They were the ones blocking change in the past, they are the ones who will decide the outcome on Friday.
