I may have missed an explanation somewhere on the thread, but I wonder if people are missing the difference between decriminalisation and legalisation?
Decriminalisation means (I think - not a lawyer) that any offences or breaches of the existing law stop being criminal offences. That doesn't mean they're not offences, and that other sanctions or measures can't be used.
So, for example, lying about your dates to get access to early medical abortion will not be a criminal offence. But systems could still be put in place to prevent this happening and midwives who colluded with it (it is usually midwives dealing with early medical abortion) would be in very serious trouble (which they couldn't be if women were legally entitled to do it).
Look, we're only a few years in to telemedicine for very early abortions, and we don't know how many (if any) women are deliberately lying about it to get later abortions. We do need to know, but women aren't going to be honest after the event if they're going to get arrested.
It may be (I hope not) that we'll find that remote access to abortion pills is not working well because too many women can't or won't give accurate information. If that were the case, we could do things to control the risks (like insisting on a scan before every termination). If it is hardly ever happening then there is no ethical or financial justification for insisting on scans for all.
So the proposers of these amendments are saying that civil measures, such as regulation, professional standards, control of the supply mechanism etc, are a far better way to control abortion services than putting women in prison.
But that is NOT legalisation. Also worth pointing out that many people are calling this a bill but it is in fact two amendments to a bill on something else, so very limited scope to do much. If an abortion bill was being introduced it would have much more detail and we'd be able to get the big picture.
A pp said this is a stupid time to be messing around with legislative change on abortion and I don't disagree with that. I just think this recent rash of women being arrested for abortion offences has forced the hand of pro-choicers. We have to protect those women - it could be any of us, or our daughters.
