The Equal Rights Amendment had passed both houses of Congress by the required 2/3 vote, then was submitted to the states for ratification.
The legal problems as I recall are:
The time limits set for passing the amendment have long passed, decades ago.
A few states which had ratified the amendment later rescinded their ratifications. Legally, nobody knows the status of those states actions.
It’s clear that the liberal view will be, that time limits for ratification can be ignored, and that states which rescinded ratification of the amendment can also be ignored.
I predict a Supreme Court ruling will eventually happen, if indeed the liberals claim that Virginia would put the amendment over the top for ratification.
The Supreme Court declined to hear the case in 1982. They won’t take the case again.
