I have an important correction to make to my column on gay marriage politics today. Massachusetts, I’m told, is unusual in that it has a law that explicitly forbids marriages to be performed for out of state couples who could not legally marry in their own state. This means that the flood of legal complication coming out of Massachusetts will be significantly reduced. Of course, there will still be major issues when actual residents of Massachusetts move to other states and seek recognition of same-sex marriages. And it’s not impossible that out of sate same-sex couples will come into Massachusetts and at least try to get married. But there does in fact seem to be a law in Massachusetts that prohibits marrying out of state couples who could not legally wed in their own state. This is an important point, and I hope to have more detail on it tomorrow.
