If the USSC protects abortion as a constitutionally privileged privacy interest in 1972, a differently constituted court in 2022 saying "that 1972 decision was total bullshit" amounts to the 2022 court removing constitutional protection from abortion rights, not extending them. Not that you or anyone else on the board needed that being explained to him.
I will preface this by saying I am pro-choice. I will also say I am anti-political and legal instability. By that I mean, I don't want the Supreme Court sending this shit back to fifty state legislatures to make their sausage on this matter. So hopefully we can have a nice civil discussion.
Unfortunately, I don't think the U.S. Constitution guarantees privacy in all matters. (I believe Canadian courts decided the matter as well long after Roe vs. Wade. Does the Canadian Constitution protect privacy rights in ALL matters?) Abortion is a far different matter than say contraceptives in Griswold vs. Connecticut.
What is of interest to me is I believe the U.S. and Canada have virtually no restrictions on abortion. This disregards States currently trying to regulate abortion. If you want an abortion, you can technically get one in the third trimester. In reality, I think this happens very rarely and it's a bit of a straw man for anti-abortion activists. Yet on the other hand, pro-abortion activists in the U.S. seem to cling to this unpopular aspect of abortion law. One side of the extreme desires an all-out prohibition and the other extreme wants unfettered access at anytime during pregnancy.
In Europe, there are restrictions and this has been done by passing laws not court decrees. The problem I see with the Courts protecting the right to an abortion is that courts can't really effectively rule on restrictions. Can the U.S. Supreme Court or any court for that matter say 15 weeks or even 20 weeks for that matter definitively say what is the right time limit for an abortion?
The best thing would be for the U.S. Congress to pass a national restriction. (It's not going to happen.) Perhaps Canada should have a restriction on abortions too. I don't know. Just thinking out loud.
Instead we are going to get 50 states passing legislation with almost as many variations on the matter. I'm not a big State's Rights guy. It seems to me to be an archaic Constitutional concept that made more sense in the days of horse travel and before the U.S. Federal government became the preeminent governing and taxing body in the country. In many privacy matters, the U.S. Federal Courts have simply taken the ball out of the States' hands. Think of it as your personal rights shouldn't be affected by who your neighbor is.
