Did I miss something here?

It appears that the CA Supreme Court is going to hear some complaints about Prop 8. Now I thought the whole purpose of a constitutional amendment, was that it creates the highest law in the land (other than the US Constitution) and so becomes the standard by which judges should make their rulings. In fact the whole issue in CA was that the voters had already passed a law affirming marriage between a man and woman, but the CA Supreme Court had shot it down as unconstitutional.

Doesn't the amendment MAKE it constitutional?

Ugh.
