An appeals court in New York has ruled that the survivor of a same-sex marriage is entitled to inheritance, even if the couple was married in another state. That's "survivor" in the probate court sense, not in the "bigamy is having one wife too many, monogamy is the same thing" sense.
New York State has a tradition of recognizing out-of-state marriages, so long as they do not "violate natural law." The court found that the only two instances in violation of natural law are incest and polygamy (despite the occurrence of both being quite common in nature). Homosexuality (also quite common in nature), the court ruled, not in violation.
We would have liked the court to rule that if Mila Kunis and Macauly Kulkin had gotten married, that also would have been a violation of natural law.
So, congratulations to what Lady Gaga describes as "all of my gays" (fka: gays), if your partner, I mean spouse dies, you can inherit all their awful CDs and ugly furniture. It does not appear this ruling would affect people who have only a civil union. If your state doesn't call your union a marriage, neither does NY.
