another jurisdiction is valid in this Court only if the marriage is not prohibited or made unlawful under this section." Lummi Nation In the Code of Laws of the Lummi Nation of Washington, Title 11 (amended on April 7, 2008) provides under section 11.01.010 "Who May Marry" that "marriage is a civil contract which may be entered into by persons of the opposite sex." Prohibited marriages per section 11.01.020 are those that would be bigamous, involve prohibited degrees of consanguinity, or when either party is mentally incompetent. Licenses may be issued per section 11.01.030 by the Lummi Tribal Court or from the county auditor of any county in the State of Washington, but no mention is made of recognizing marriages performed in other jurisdictions. On March 3, 2004, a same-sex marriage between a member of the Lummi Nation occurred in Oregon. Muscogee (Creek) Nation Same-sex marriage is banned by the Muscogee (Creek) Nation, even when legally performed elsewhere in the state of Oklahoma. Title 6, Chapter 2, section 104-G of the Tribal Code states, "same gender marriage prohibited. A marriage between persons of the same gender performed in another Indian Nation or state shall not be recognized as valid and binding in the Muscogee (Creek) Nation." This was passed and approved on September 7, 2001. However, many Tribal services are accorded to the household, rather than specifically to a married couple, so in many situations the lack of recognition of a marriage has little effect. As in the other Oklahoma Tribal Statistical Areas governed by one of the "Five Civilized Tribes", all of which are inhabited by a majority non-native population, Muscogee (Creek) authority only extends to Tribal members and property. Non-members, who do not receive services from the Tribal Government and are not subject to the Tribal Code, are unaffected by the ban on same-sex marriage. Navajo Nation Same-sex marriage is not valid under Navajo law. It was explicitly prohibited by the Diné Marriage Act, an amendment to the Tribal Code enacted on April 22, 2005. The act was vetoed by Navajo President Joe Shirley, Jr., but the veto was overridden by the Navajo Nation Council. In the run-up to the 2018 elections, both Shirley and his opponent, Jonathan Nez, said they strongly supported a repeal of the act, and Shirley said they had 14 of the 16 votes needed on the Council for repeal, but after few months
