It hasn't been mentioned I don't think, but the United States Supreme Court is set to hear two interesting cases revolving around same-sex marriage.
The first is United States vs Windsor It concerns a woman named Edie Windsor who lived with and was registered as domestic partners with another lady named Thea Spyer since 1993 (and they had actually been together more than 40 years.) In 2007, Spyer contracted MS. They went to Canada and got married that year, and later Spyer passed away in 2009. New York, where they live, recognized their marriage, but the US Federal Government did not. Because Windsor had no spousal rights, she ended up having to pay $363,053 in estate taxes. Had she been married to a man, her tax bill would have been $0!!
The second is Hollingsworth vs Perry which said it was unconstitutional for voters California to pass Prop 8 banning gay marriage after the state supreme court had legalized it. They won in lower courts, with the rulings being limited only to California, but Prop 8 supporters have made it bigger. They wrote in the petition to the high court, “The 9th Circuit’s sweeping dismissal of the important societal interests served the traditional definition of marriage is tantamount to a judicial death sentence for traditional marriage laws throughout this Circuit.”
The first (US v W) looks like a winner, and it's only fair that someone you've shared so much of your life with be granted full inheritance rights. It could be dealt with with other laws regarding inheritance though, and a win, while important, is really only a baby-step towards recognition of same-sex marriage.
The other (H v Perry) has the potential to make same-sex marriage legal throughout the whole United States in one fell swoop. The question is, are the justices prepared to make that giant step? Some advocates are nervous that this is too much too soon, and a defeat could set the movement back several years.
It's going to be an interesting year.
