The Coquille Indian Tribe has adopted a law that recognizes same-sex marriage.

Oregon voters amended the state constitution in 2004 to prohibit gay marriage. But as a federally recognized sovereign nation, the tribe is not bound by the Oregon Constitution.

The Coquilles are believed to be first tribe in the nation to legalize same-sex marriage. It's unclear if the federal government could challenge the Coquille law as a way of testing the limits of tribal independence.
