The feds stuck their noses into marriage ages ago & there is a lot of case-law in all 50 states to show that all 50 have allowed them to do it.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.
I don't know any of the case-law, but I know it's there. Some states were allowing marriages of 12, 13 year olds, while others had an older age requirement. After the couples moved to a state that had an older requirement, they were discovering their marriages were no longer being recognized & I'm sure statatory rape laws were getting triggered.
