Are you talking about the US? I though the Equal Rights Amendment was not yet ratified, and that equal rights are thus not actually 'constitutionally enshrined'?
The ERA is not the only way or attempt in the Constitution at enshrining equal rights. The ERA is about sex specifically, which is arguably already covered by the text of the 14th Amendment (some may disagree about the 14th Amendment in practice, but it's hard to argue that the text doesn't cover sex).
