But clearly those who argued that the federal Defense of Marriage Act would stop the export of same-sex marriage were wrong, and that basis for opposing the Marriage Amendment revealed as threadbare.I wouldn't go that far yet. As far as I can tell, this is a bad legal ruling. Not bad as in "I disagree" but bad from a point of law. The July 6, 2006 ruling by the New York Court of Appeals did not establish a marriage prohibition in the state of New York. Instead it upheld an existing same-sex marriage prohibition which would indicate all prior same-sex marriages were illegal.
To say that DOMA has proven insufficient is inaccurate since we have yet to see same-sex marriage enter a federal court where DOMA would apply. This may be the case if New York refuses to recognize the Massachusetts decision.
