When I said that today's partial birth abortion opinion was "big," I meant it. I just read one commentator at Scotusblog talking about what, if anything, is left of Roe v. Wade. While I certainly don't go as far as that commentator, we will be talking about this decision for a long time. The landscape of abortion jurisprudence has changed.
But don't go too far. Today's opinion only addressed one abortion procedure--Roe addressed every abortion procedure before viability.
I think the most lasting effect of this decision will be that states and pro-life litigators will become more active in testing the foundation of Roe. There will be a lot of abortion cases for the next few years. What, if anything, comes of those cases is still up in the air.
