Not that I’m an expert, but Plessy v Ferguson is the last time I can think of that a fundamental right was rescinded by the Court. Fucking Reconstruction. That’s what we’re talking here. It’s really astounding, even not considering abortion per se. Dred Scot: you’re not free, and you’re not actually a human. The Civil War: actually yeah you are. Plessy: not so fast.
Interesting note is that the Equal Rights Amendment never got all the votes it needed to be passed, but there are only 3 states who have not signed it yet... and it has never been rescinded. So, at any point, those three states could ratify the ERA and it would become a Constitutional Amendment. I've seen some scholars talking about IF that could happen, and what would happen if it did... but there simply isn't an expiration date on Constitutional Amendments. So ... it could happen. (But Democrats would have to Do Something, and you know that's out of the question.)
I believe Tennessee and maybe one or two other states passed resolutions disavowing their ratification, but some scholars seem to think there’s not actually a legal mechanism to do that. Whatever the case, it would be fascinating to watch. Some amendments have taken many years to ratify, so there is precedent for that.
