Marriage? Montana Money
The Montana State Supreme Court has just ruled that, irrespective of issues of marriage, denying spousal benefits to the domestic partners of homosexual employees is a denial of their economic rights. Montana is, apparently, a common-law-marriage state, but allowing only heterosexuals to claim the benefits of marriage by simple affidavit was seen as a violation of equal protection.
It's kind of surprising, really, that common-law marriage hadn't entered the debate before now.
Update: Ralph's comment reminded me that I meant to post a link to this discussion of contemporary marriage which has nice demographic discussions. One of the interesting things it points out which I hadn't really considered was the way in which the liberalization of adoption and foster parenting rules has broadened the definition of"family" in ways that reflect on our definition of"marriage." In related news, as the NYTimes article cited above notes, an Arkansas judge struck down that state's ban on gay foster parents, but strictly on procedural grounds.
