[JURIST] The Navajo Nation's Tribal Council voted Friday to override Navajo President Joe Shirley Jr.'s [Navajo Nation profile] veto of a same-sex marriage ban [JURIST report] it approved last month for the UnitedS States' largest Indian reservation. The Dine Marriage Act of 2005 defined marriage as a relationship between a man and a woman. The vote on the veto override was 62-14 with one delegate explaining why gay marriage is forbidden by the Navajo ways: "It all boils down to the circle of life. We were put on this earth to produce offspring." The Navajo Nation [official website] has over 180,000 residents in areas of New Mexico, Arizona and Utah. Navajo President Shirley recently discussed gay marriage in Native America on Democracy Now [transcript and audio]. AP has more.
