The Defense Of Marriage Act (DOMA), which prevented the Social Security Administration and other agencies from recognizing same sex marriages, has been found
unconstitutional by the Supreme Court.
Unfortunately, this leaves open the question of whether Social Security can recognize same sex marriages when the married person has moved to a state that refuses to recognize same sex marriages since the Social Security Act relies upon the law of the state in which the person is domiciled. Apparently, the ruling is so broad that it is likely that the Court will rule that state laws that refuse to recognize same sex marriages solemnized in other states are also unconstitutional. However, it will probably be at least a year before the Supreme Court rules on that issue. In the meantime, my
bet is that Social Security will, at the least, recognize the same sex marriages of those who have moved to a state that refuses to recognize same sex marriages as
deemed marriages.
Update: On second thought, I can't bet on deemed marriage being the solution because the statute says that the only sort of legal impediment that qualifies one for a deemed marriage is "an impediment (I) resulting from the lack of
dissolution of a previous marriage or otherwise arising out of such
previous marriage or its dissolution, or (II) resulting from a defect
in the procedure followed in connection with such purported marriage." Neither of these applies to a situation where a person duly married in one state moves to another state which refuses to give full faith and credit to the marriage.
Update: It's not particularly relevant to Social Security but you ought to read some of
what Justice Scalia said in dissent. Let's just say, he really disagreed with the majority opinion which he categorized as "black-robed supremacy." He had a few other things to say as well. As we say in the South, bless his heart.
