As noted in the article "The Equal Rights Amendment May Pass Now. It’s Only Been 96 Years" there is at least a nonzero chance that the ERA could become part of the Constitution.
Putting aside the issues of the validity of the ERA, assuming it were to become part of the Constitution, what practical effects would it have today?
Its main clause reads,
“Equality of rights under the law shall not be denied or abridged by the United States or by any State on account of sex”
which I had thought was similar to various existing Federal laws regulating certain areas. Perhaps the ERA would cover a broader set of state & federal laws? Or given the existing laws on the books would it amount to mostly a 'ceremonial' change?
