The Equal Rights Amendment died in 1982, lacking state ratification before the deadline expired. Phyllis Schlafly, among many successfully argued that the ERA amendment was designed to allow activist judges to create law that the legislative process rejected. Four states that had ratified the ERA amendment later rescinded their approval (Idaho, S. Dakota, Tennessee and Kentucky). The supreme court has left it up to congress whether to allow states to back out of an amendment they had approved earlier.
Despite missing the deadline by decades, Nevada passed the amendment last year, followed yesterday by Illinois. That leaves them one state short of the 38 needed, assuming congress won’t allow individual states to rescind their approval. More
The left hasn’t given up on the ERA though, the amendment keeps getting reintroduced to congress at the beginning of every session (Ted Kennedy kept it up until his death) and there continues to be efforts by congressional democrats to lift the deadline, which would give them an indefinite date to finally get that last state to approve the amendment.
