Ultimately if the Supreme Court were to take up the issue and decide that there is no constitutional right to homosexual marriage, then all these marriages in all these states that have laws on the books prohibiting homosexual marriage (like California) would be void and the laws would be put into effect as if they were never overturned.
This is why these State Attorney Generals (like in Arizona) are not attempting to challenge these rulings. They are all either overtly or secretly opposed to the will of the people of their states.
The Supreme Court turning down the Homosexual Marriage cases was an act of Cowardice. They know they would probably have to rule that there is no such constitutional right and what they are doing as a group is to wait until it is “settled law” then they can rely on the fact that this is something that “The American People overwhelmingly support” even though they have never supported it at all.
