; Executive order of January 8, 1900; Public Law 72–403 , 47 Stat. 1418 (1933); and Public Law 73–352 , 48 Stat. 960 (1934). (4) The Navajo Indian Reservation presently encompasses lands of the San Juan Southern Paiute Tribe as described in the Treaty between the Navajo Nation and the San Juan Southern Paiute Tribe. (5) While the Diné people of the Navajo Nation and the Paiute people of the San Juan Southern Paiute Tribe have a long history as neighboring communities, the San Juan Southern Paiute people are a separate and culturally distinct Tribe residing within their ancestral lands. (6) The existence of the San Juan Southern Paiute Tribe within the exterior boundaries of the Navajo Indian Reservation and the lack of an exclusive reservation land base causes particular hardship for the people of the San Juan Southern Paiute Tribe, preventing the Tribe from providing adequate housing, infrastructure, healthcare, community services, and public safety for its people. (7) The San Juan Southern Paiute Tribe and the Navajo Nation entered into a Treaty on March 18, 2000, to resolve and clarify the sovereign authority of both Tribal nations, to provide a permanent homeland for the San Juan Southern Paiute Tribe, and to resolve other matters of mutual concern. (8) Ratification and approval of the Treaty by Congress and the execution of the Treaty by the Secretary is necessary for the Treaty to become effective under its terms. (9) The establishment and proclamation of the San Juan Southern Paiute Reservation as authorized in this Act only includes lands within the existing boundaries of the Navajo Indian Reservation. (10) Once effective, the Treaty will— (A) resolve and cause the dismissal of long-running litigation concerning certain land rights of the Navajo Nation and San Juan Southern Paiute Tribe currently pending before the United States Court of Appeals for the Ninth Circuit (Masayesva v. Zah et al., No. 93–15216 (9th Cir.)
