However, it is the the perogative of the states to define who may enter the marriage contract, not the perogative of the federal government. Do you have some examples of the case law? I would like to look them up and study them, so I learn a little more about this issue.
Defense of marriage may not be sufficient to exempt Florida from recognizing the California marriage.
But it has never been challenged (to my knowledge), so no one really knows what it may, or may not do.
