Became Public Law No: 113-134.

What it does
This law transfers approximately 20 acres of federal land in Arizona — in two roughly 10-acre parcels — into trust status for the Pascua Yaqui Tribe. The transfer of the second parcel takes effect only after the Tucson Unified School District gives up its interest in that land and the Secretary of the Interior approves a lease allowing a regional transportation facility to be built there. Gaming is explicitly prohibited on both parcels, and the Tribe's existing water rights attached to the land are preserved.
Who benefits
The Pascua Yaqui Tribe of Arizona gains formal federal trust title to approximately 20 acres, expanding its land base and the legal protections that come with trust status (e.g., exemption from state and local property taxes, stronger federal protections against alienation). The Tucson Unified School District benefits indirectly by securing a lease for a regional transportation facility on Tribe-restricted land, which it could not otherwise access. Tribal members who use or live near the parcels would benefit from the expanded land base.
Who is hurt
Arizona state and local governments would lose any potential property tax revenue from the parcels once they move into federal trust status, as trust land is generally exempt from state and local taxation. Neighboring landowners or businesses that might have preferred alternative uses for the parcels — including commercial or gaming development — are foreclosed by the gaming prohibition. Any parties who held competing claims or interests in the land would lose those claims upon conveyance.
Supporters argue
Supporters argue that placing this land into trust fulfills a longstanding federal obligation to the Pascua Yaqui Tribe, which was only formally recognized by Congress in 1978 and has a comparatively small land base relative to other federally recognized tribes. They contend that trust status provides the Tribe with the legal stability and economic foundation necessary for self-governance and self-sufficiency — core goals of federal Indian policy since the Indian Self-Determination and Education Assistance Act of 1975. Supporters also note that the conditions attached to Parcel B — requiring the School District's cooperation and a Secretary-approved lease — ensure the transfer serves a broader community purpose by enabling a regional transportation facility. The explicit gaming prohibition, they argue, addresses the most common local concern about trust land acquisitions, making this a narrowly tailored and community-supported measure.
Opponents argue
Opponents argue that transferring land into federal trust removes it permanently from state and local jurisdiction, depriving Arizona and Tucson-area governments of tax revenue and regulatory authority over the parcels with little opportunity for public input or recourse. They contend that the Indian Reorganization Act's trust acquisition process — and its application to tribes recognized after 1934, like the Pascua Yaqui — remains legally contested following the Supreme Court's decision in Carcieri v. Salazar (2009), raising questions about whether such transfers are on solid legal footing. Critics also argue that legislating individual land-into-trust transfers through standalone bills, rather than through the standard administrative process overseen by the Bureau of Indian Affairs, bypasses established regulatory review and sets a precedent that could be used to circumvent normal oversight for future, potentially larger or more controversial acquisitions.
Constitutional context
The primary constitutional authority for this legislation is the Indian Commerce Clause (Art. I, Sec. 8, Cl. 3), which grants Congress broad power to regulate affairs with Indian tribes. The trust land framework also draws on Congress's plenary power over Indian affairs, recognized in cases such as Morton v. Mancari (1974). The Equal Protection Clause (14th Amendment) is tangentially relevant, as federal Indian law classifications are generally reviewed under rational basis rather than strict scrutiny when tied to the political status of tribes (Morton v. Mancari). The Shelby County v. Holder (2013) and Carcieri v. Salazar (2009) lines of cases are relevant to the scope of federal authority and the definition of "Indian" under the Indian Reorganization Act of 1934.
Checks and balances
The Executive Branch (Secretary of the Interior) retains a conditional gatekeeping role: the Parcel B transfer cannot take effect until the Secretary approves and records the lease agreement with the Tucson Unified School District. This preserves some Executive oversight over the timing and terms of the conveyance. Congress exercises its plenary authority over Indian affairs directly through legislation, bypassing the standard administrative trust acquisition process (25 C.F.R. Part 151), which would normally involve Bureau of Indian Affairs review and state and local government comment periods.
Historical precedent
Numerous standalone trust land acts have been passed for specific tribes, including the Lytton Rancheria of California Land Act (2000) and various other tribe-specific land conveyances. The broader framework traces to the Indian Reorganization Act of 1934. The post-Carcieri v. Salazar (2009) environment has made legislative trust acquisitions more common as an alternative to the administrative process.
