Legal in Mass. today by judicial fiat. Other states, even those with Defense of Marriage Acts, will soon have to recongnize these marriages by the Full Faith and Credit clause of the US Const.
Major campaign issue in 2004.
Edit: After further review, it appears that the court has punted the case back to the legislature. The representatives will have 180 days to further define marrigage, and then the court may revisit the issue. It seems to me that if the Mass. legislature reaffirms marriage as between a man and woman, than the court may defer to it.
